Defendants Robinhood Markets, Inc., Robinhood Financial LLC and Robinhood Securities, LLC's Memorandum of Points and Authorities in Opposition to Plaintiffs' Motion for Class Certification — In re January 2021 Short Squeeze Trading Litigation (Dkt. 567, S.D. Fla.)

Summary

Defendants Robinhood Markets, Inc., Robinhood Financial LLC and Robinhood Securities, LLC's Memorandum of Points and Authorities in Opposition to Plaintiffs' Motion for Class Certification in In re: January 2021 Short Squeeze Trading Litigation, Case 1:21-md-02989-CMA (Case No. 21-MD-2989-ALTONAGA/DAMIAN, Document 567, 45 pages), in the Southern District of Florida, entered June 7, 2023. Robinhood argues that retail investors drove up the meme stocks in a social media frenzy and that reliance and damages would be individualized, with neither the Basic nor the Affiliated Ute presumption available, precluding certification under Rule 23(b)(3). The memorandum also argues that the Named Plaintiffs fail Rules 23(a)(3) and 23(a)(4) and asks for a hearing joined with any Daubert hearing, over the /s/ signature of Samuel A. Danon of Hunton Andrews Kurth LLP.

                                            INTRODUCTION
          Plaintiffs accuse Robinhood of manipulating the markets for certain “meme stocks.” In
   reality, it was retail investors like the Named Plaintiffs who drove up the price of the specified
   stocks in a social media frenzy that created a bubble doomed to burst. During that frenzy, the
   prices for those stocks were completely untethered from the actual value of the underlying
   companies. This inescapable fact makes this case unsuitable for resolution as a class action.
   Unlike in a typical securities fraud case for exchange-traded stocks, in which a defendant makes
   a common misrepresentation and the court can presume class members relied on it, Plaintiffs
   here cannot show that members of the putative class, including investors who did not trade on
   (and may never have heard of) Robinhood, relied on any statement Robinhood made regarding
   the reasons for its trading restrictions in deciding whether to hold or sell their shares of other
   companies’ stock. Nor can Plaintiffs establish that they relied on the integrity of the market.
          Instead, the evidence—including the sworn testimony of numerous Named Plaintiffs—
   establishes that many of the putative class members traded with full knowledge of black swan
   market events, attempting to take advantage of real or perceived short squeezes driving these
   stocks to their breathtaking prices. Predictably, the bubble burst and the stocks returned to their
   true prices. This coincided with Robinhood’s imposition of the purchasing restrictions, which all
   but one Named Plaintiff admit they knew about when they sold their shares. As with any bubble,
   some people made money and, depending on timing, others lost money. Plaintiffs now seek to
   certify a class of individuals who purportedly lost on their trades when the bubble burst. (Dkt.
   No. 559 (the “Mot.”).) Their motion should be rejected on four independent grounds.
          First, Plaintiffs cannot satisfy the predominance requirement of Federal Rule of Civil
   Procedure 23(b)(3) because reliance—an element of each of their claims—cannot be presumed
   classwide. As a result, each putative class member’s reliance (or lack thereof) will be an
   individualized inquiry. That is because the markets for the Affected Stocks were not efficient
   during the Class Period (or the immediate run-up to the Class Period), precluding Plaintiffs from
   invoking the presumption of reliance set forth in Basic Inc. v. Levinson, 485 U.S. 224 (1988) that
   plaintiffs in securities fraud class actions can typically satisfy. In addition to the fact discovery
   from Named Plaintiffs and other investors, the accompanying reports of Robinhood’s experts,
   Prof. Steven Grenadier and Prof. Daniel Fischel, set out evidence that the markets for the
   Affected Stocks were not efficient during this unusual time period and explain why the efficient
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 9 of 45




   market theory does not apply. Plaintiffs’ attempts to avoid the Basic requirement to show
   efficient markets fail, as neither the “common scheme” doctrine nor the presumption of reliance
   under Affiliated Ute v. United States, 406 U.S. 128 (1972), applies. (See Part I.)
          Second, Plaintiffs cannot satisfy the predominance requirement of Rule 23(b)(3) for the
   separate reason that they cannot establish that their damages are measurable on a classwide basis
   using a common methodology that is consistent with their theory of liability, as required under
   Comcast Corp. v. Behrend, 569 U.S. 27 (2013). A reliable damages model must account for the
   fact that the prices of the Affected Stocks in the pre-Class Period were artificially inflated, and
   Plaintiffs have not put forward a reliable methodology to determine the but-for price had
   Robinhood never put the purchase restrictions in place. Plaintiffs’ failure to establish that the
   markets for the Affected Stocks were efficient on January 27, the day before the Class Period, is
   fatal to their damages methodology. (See Part II.)
          Third, Named Plaintiffs lack standing to bring certain claims and are subject to unique
   defenses that preclude certification under the typicality requirement of Rule 23(a)(4). Discovery
   has shown that the proposed lead plaintiff, Blue Laine-Beveridge, is not a class member at all or
   at a minimum, he is atypical because he profited on his trades. Without a lead plaintiff, the class
   cannot be certified. Moreover, all of the Named Plaintiffs testified that they did not rely on the
   integrity of the market and instead engaged in unusual trading practices—such as not conducting
   research, trading based on price movements, buying and selling the same security in a single
   trading day and investing at the recommendation of social media influencers. These haphazard
   trading practices, which are not typical of all traders, give rise to unique defenses. Further, none
   of the Named Plaintiffs suffered losses from transactions in four of the Affected Stocks (BBBY,
   KOSS, TR and TRVG), so they lack standing to sue regarding those stocks. (See Part III.)
          Fourth, the Named Plaintiffs will not adequately prosecute the action as required by Rule
   23(a)(4). Named Plaintiffs’ deposition testimony demonstrates that they have failed to take an
   active role in overseeing the case and do not even understand the substance of the action. In the
   most egregious display of a named plaintiff’s disregard of his obligations, one Named Plaintiff
   sat for his entire four-hour deposition while he was driving his car. (See Part IV.)

                                         STATEMENT OF FACTS
    I.        ROBINHOOD AND RETAIL TRADING
              Robinhood has democratized finance by providing access to financial markets with its
    zero-commission trades, no account minimums, and a platform available on a computer or
    mobile device. Customer trading on Robinhood is largely self-directed. (Ex. 58, Robinhood
    2021 10-K at 6.) When a Robinhood customer initiates a trade, Robinhood Financial—the
    introducing broker—decides whether to accept the order. If it does, Robinhood Financial sends
    the order to Robinhood Securities, the clearing broker, which routes the order to a market maker
    for execution. (Ex. 60, Robinhood Blog Post, “What happened this week” (Jan. 29, 2021).)
              After the trade is executed, Robinhood Securities submits it to a clearinghouse for
    clearance and settlement. (Id.) The main clearinghouse for equities traded in the U.S. is the
    National Securities Clearing Corporation (“NSCC”). (Ex. 20, Grenadier Report ¶ 53.) To
    mitigate the risk that market participants will be unable to satisfy their obligations, clearing
    brokers, including Robinhood Securities, must post collateral (also referred to as deposit
    requirements) with NSCC to cover the risk until the trade settles. These deposit requirements
    fluctuate day to day, and depending on NSCC’s calculations, Robinhood may be required to
    deposit additional funds to meet its obligations. (Id. ¶¶ 53-54.) In setting deposit requirements,
    NSCC considers market volatility generally as well as the volatility in specific securities, and, in
    its discretion, may also apply an excess capital premium (“ECP”). (Id. ¶ 54 & n.101.) If a
    clearing broker does not meet its deposit requirements, NSCC could liquidate the broker’s entire
    portfolio, inclusive of its customers’ positions. (Ex. 63, HFSC Report at 64.)
    II.       MEME STOCKS, RETAIL INVESTORS COORDINATING ON SOCIAL MEDIA
              AND SHORT SQUEEZES
              In late January 2021, leading up to the proposed Class Period, retail investors banded
    together through online forums to drive a massive short squeeze involving certain stocks
    (referred to as “meme stocks”) they perceived to be heavily shorted by hedge funds. (Ex. 18,
    Fischel Report ¶ 8; Ex. 20, Grenadier Report ¶¶ 113-114.) 1 While retail investors had various

          1
           Plaintiffs claim an SEC Staff Report “cast[s] doubt on the short squeeze at the center of
    Robinhood’s experts’ narrative” (Mot. at 6), but they ignore that the very paragraph they cite
    states: “[t]he price surge in GME [] raises questions of market efficiency that relate to short
    selling.” (Dkt No. 559-12 at 30.) Indeed, the report observed that it was “unusually costly to
    borrow shares in GME,” and that “constraints on short selling” can contribute to “bubbles where



                                                       3
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 11 of 45




    motivations for trading, with some seeking to harm hedge funds with short positions, others
    seeking to profit from possible squeezes and still others seeking entertainment, this spike in retail
    investor trading activity resulted in extreme market volatility and dramatic run-ups of the nine
    stocks at issue in this case. (Ex. 18, Fischel Report ¶ 9; Ex. 20, Grenadier Report ¶¶ 114-118.)
            One social media forum that retail investors used to gin up enthusiasm for the meme
    stocks was the WallStreetBets page on Reddit. Certain high-profile retail investors’ posts on
    WallStreetBets and other social media platforms were particularly effective in fueling the fires of
    the meme stock movement. Keith Gill, for example, known by his social media usernames
    “Roaring Kitty” or “DeepF***ingValue,” posted videos encouraging investment in GME that
    were widely cited on WallStreetBets and have over a million views. 2 Gill also posted
    screenshots of his meme stock investments, prompting followers—including Named Plaintiff
    Sandy Ng—to post comments professing support, such as “IF HE’S STILL IN, I’M STILL IN.”
    (Ex. 45, Dep. Ex. 40 at 1.) Likewise, Alvan Chow authored popular GME posts on
    WallStreetBets in late 2020 and early 2021 in which he predicted short squeezes would drive up
    the stock price and reward the WallStreetBets “gamblers” for opposing larger funds. (Ex. 22,
    Dep. Ex. 207 at 1; Ex. 53, Dep. Ex. 209 at 1; Ex. 54, Dep. Ex. 210 at 1.) At his deposition,
    Mr. Chow characterized the subreddit as “a community known for very reckless investments, to
    the point where they’re not investments.” (Ex. 4, Chow 40:16-21.) As part of the mania, retail
    investors, including certain Named Plaintiffs, posted or placed joke orders or joke price targets
    with sexual and drug references including the numbers “69” and “4/20.” (See, e.g., Ex. 5, Clarke
    112:24-113:13; Ex. 14, Rivas 106:14-108:17; Ex. 4, Chow 111:3-19.)
            These posts proved effective. The stock prices of the nine meme stocks that are the
    subject of this litigation—AMC, BBBY, BB, EXPR, GME, KOSS, NOK, TR and TRVG—




    stock prices rise above what may be justified by fundamentals.” (Id.) Thus, “the reluctance to
    sell short could have contributed to the run-up in prices and the subsequent steep decline.” (Id.)

    experienced a roller-coaster ride up and down in late January 2021. 3 For example, GME’s price
    rose a remarkable 788% in the five trading days preceding the proposed Class Period (i.e.,
    through January 27, 2021). (Ex. 20, Grenadier Report, fig. 2.) KOSS’s stock price rose 1,591%
    over the same period. (Id.) These price run-ups occurred despite the absence of any news about
    the value of these companies that could remotely justify the increases. (Id. ¶ 104.) A number of
    the companies issued press releases commenting on the unusual events. For example, on January
    25, BlackBerry issued a press release stating that it was “not aware of any material, undisclosed
    corporate developments and has no material change in its business or affairs that has not been
    publicly disclosed that would account for the recent increase in the market price or trading
    volume of its common shares.” (Ex. 42, BlackBerry Press Release, Jan. 25, 2021.) On
    January 27, 2021, Nokia issued a similar release. (Ex. 57, Nokia Press Release, Jan. 27, 2023.) 4
            There is no doubt that these price movements were driven by the social media craze
    rather than company news. On January 26, for example, GME’s share price increased by over
    60% in after-hours trading after Elon Musk tweeted “GameStonk!!” with a link to
    WallStreetBets. (Ex. 43, Dep. Ex. 15.) 5 Similarly, on January 22 the stock price of EXPR
    increased by 40% after Will Meade, an investment commentator with a significant Twitter
    following, tweeted that EXPR could be the next GME. (Ex. 55, Dep. Ex. 301.) When asked at
    his deposition about news that might account for the stock price movements, Mr. Meade testified
    that “the only news was that everyone in the trading community and Wall Street was looking for
    the next GameStop.” (Ex. 10, Meade 94:8-23, 114:20-23.) Robinhood’s expert, Prof. Grenadier,
    found that eight of the nine Affected Stocks experienced their highest five-day return over the
    previous 25 years in the days preceding January 27, 2021. (Ex. 20, Grenadier Report ¶¶ 19, 78.)
    In the five trading days between January 21 and January 27, 2021, the total daily volume for the

        3
           The nine companies are AMC Entertainment Holdings, Inc.; Bed Bath & Beyond Inc.;
    BlackBerry Ltd.; Express Inc.; GameStop Corp.; Koss Corp.; Nokia Oyj; Tootsie Roll Industries,
    Inc.; and trivago N.V. Plaintiffs call these stocks the “Affected Stocks.” (Dkt. No. 527-0, Am.
    Compl. ¶ 1.)
        4
         After the Class Period, AMC, EXPR, GME and KOSS also included statements in their
    SEC filings disclaiming knowledge of undisclosed information or changes in their business that
    would explain the price movements. (See AMC 10-K, March 12, 2021; Express Form 10-K,
    March 25, 2021; GameStop 10-K, March 23, 2021; Koss Form 10-Q, May 13, 2021.)
        5
          Mr. Chow testified that he liquidated his positions after Mr. Musk’s tweet because he
    believed the tweet “signaled the height of the mania.” (Ex. 4, Chow 128:12-24.)

    Affected Stocks increased extraordinarily, by almost fifteen-fold. (See Market Activity, Nasdaq,
    https://www.nasdaq.com/market-activity; see also Ex. 20, Grenadier Report ¶¶ 92-96.)
    III.       COLLATERAL REQUIREMENTS AND TRADING RESTRICTIONS IMPOSED
               BY ROBINHOOD AND OTHER RETAIL BROKERAGES
               During this period of frenetic trading, Robinhood sought to manage the impact that
    increasing volatility could have on its NSCC deposit requirements. Robinhood’s daily deposit
    requirements with NSCC steadily increased throughout January, reaching $690 million by the
    evening of January 27, 2021, an approximately ten-fold increase from the start of the month.
    (Ex. 20, Grenadier Report ¶ 54 & fig. 1; Ex. 36, RHMDL00020635.) For certain volatile stocks
    like GME that did not already require 100% initial and maintenance margin requirements,
    Robinhood increased the margin requirements to 100%, which meant that customers needed
    funds to pay for those shares in full, rather than being able to buy shares with credit. (Id. ¶¶ 46
    & 50.) Robinhood implemented these requirements to mitigate the risk that its customers might
    default on their ability to pay for volatile stocks. In the pre-Class Period, Robinhood also limited
    the number of options for certain stocks that customers could purchase and increased capital
    requirements for customers seeking to exercise options. (Ex. 38, RHMDL00047970.)
               Before the markets opened on the morning of January 28, 2021, Robinhood Securities
    received a notice from NSCC stating that its deposit requirements had jumped dramatically, to
    over $3 billion, now nearly 20 times the deposit requirement from the start of the month and
    almost 5 times what it had been the day before. (Ex. 18, Fischel Report ¶ 12; Ex. 20, Grenadier
    Report ¶ 54 & fig. 1; Ex. 36, RHMDL00020635.) The $3 billion deposit requirement included a
    charge due to market volatility of over $1.2 billion and an additional charge (the excessive
    capital premium or “ECP”) of over $2.2 billion because of the ratio of Robinhood Securities’
    deposit requirements to its on-hand capital. (Ex. 37, RHMDL00045649.) 6 As a result,


           6
          Plaintiffs cite to a discussion among three Robinhood employees to suggest that
    Robinhood was “unaware of” the ECP component of its clearinghouse deposit. (Mot. at 5.)
    None of those employees’ responsibilities, however, has anything to do with the securities
    clearing processes and procedures, and as Plaintiffs well know from the documents Robinhood
    has produced in this action, the employees with such responsibilities were aware of the various
    components of NSCC deposit requirements. (See, e.g., Ex. 35, RHMDL00011594 (NSCC Risk
    Margin Component Guide, from files of Robinhood Director of Financial Risk &
    Analytics).) Plaintiffs also ignore the highly unusual nature of the ECP charge. The House
    Report (which Plaintiffs cite repeatedly) states: “It is worth noting that 3 of the 4 times an Excess



                                                       6
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 14 of 45




    Robinhood decided to temporarily set a number of the meme stocks to “position closing only”
    (“PCO”), which permitted Robinhood customers to sell positions in those stocks if they wished,
    but restricted new purchases of those volatile stocks. The thirteen PCO’ed stocks include the
    nine at issue in this case, plus four others (AAL, CTRM, NAKD and SNDL). 7 (Ex. 38,
    RHMDL00047970.) Robinhood announced the PCO restrictions in a blog post on the morning
    of January 28, explaining that they were being implemented because of recent market volatility.
    (Ex. 34, RHMDL00002200.) Shortly after Robinhood informed NSCC that it would implement
    these restrictions, NSCC reduced Robinhood’s deposit requirements to roughly $1.4 billion
    (predominantly the volatility-driven charge), which Robinhood paid so it could continue serving
    all of its customers. (See Ex. 37, RHMDL00045649; Ex. 20, Grenadier Report ¶ 54 & fig. 1.)
            As Plaintiffs concede, Robinhood’s next public statement concerning the PCO
    restrictions occurred after trading closed on January 28 (i.e., after the end of the first day of the
    proposed Class Period). (Mot. at 11.) That evening, CEO Vlad Tenev gave an interview on
    CNBC regarding the day’s unprecedented events. 8 Mr. Tenev accurately described the PCO
    restrictions and truthfully explained that Robinhood “absolutely did not do this at the direction of
    any market maker, or hedge fund, or anyone we route to, or other market participants” but rather
    due to Robinhood’s financial requirements, including clearinghouse deposits. 9


    Capital Premium charge was calculated for Robinhood was during the Meme Stock Market
    Event.” (Ex. 63, HFSC Report n.577.)
        7
         These companies are American Airlines Group Inc., Castor Maritime Inc., Naked Brand
    Group Ltd. (now known as Cenntro Electric Group Ltd.) and Sundial Growers Inc. (now known
    as SNDL Inc.).

        9
          Plaintiffs misleadingly assert that Robinhood employees were dissatisfied with
    Robinhood’s messaging. Plaintiffs quote an employee telling COO Gretchen Howard that
    “[Robinhood] should fully lay out our cards” and tell the public “about what’s happening behind
    the scenes” (Mot. at 12-13), but omit Howard’s response that a “blog post [was] written” (what
    became Ex. 59, Robinhood Blog Post, “An update on market volatility” (Jan. 28, 2021)) and
    “waiting on approval” (Ex. 67, RHMDL00005649-50). Plaintiffs likewise cherry-pick questions
    asked about Mr. Tenev’s public comments at a January 29 employee Q&A, conveniently
    ignoring those that are inconsistent with their narrative. (See, e.g., Ex. 66, RHMDL00044035 at
    ‘036 (“There’s been a lot of out reach to traditional media to explain what happened.”).)

Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 15 of 45




              As Mr. Tenev explained, other brokers similarly imposed restrictions on meme stocks
    during this period of unprecedented volatility. For example, Apex Clearing Corporation, a
    clearing broker used by many introducing brokers, imposed restrictions on AMC, GME and
    KOSS that impacted approximately 13 million customer accounts across Apex’s 73 introducing
    broker partners (including Ally, WeBull and Alpaca). (Ex. 18, Fischel Report ¶ 40; Ex. 20,
    Grenadier Report ¶¶ 48-49 & n.71.) E*TRADE also limited purchases of GME and AMC on
    January 28, 2021. (Id.) These brokerages’ millions of customers accounted for a significant
    portion of the trading volume in the Affected Stocks in the run-up to the Class Period. In fact,
    contrary to Plaintiffs’ assertion (Mot. at 5), on average, buy volume on Robinhood accounted for
    only 4.5% of the total market trading volume across the Affected Stocks during the week prior to
    the proposed Class Period. (Ex. 20, Grenadier Report ¶ 150 & Ex. 17.)
              The PCO restrictions remained in place for only one day, January 28. (Ex. 20, Grenadier
    Report ¶ 50.) By market open on January 29, Robinhood modified the PCO restrictions to place
    caps on additional purchases (i.e., a limit on the number of additional shares a customer could
    purchase in certain stocks) and began lifting purchase limits until all of them were lifted by the
    end of the day on February 4, 2021. (Ex. 20, Grenadier Report ¶ 52.) During this period,
    Robinhood regularly updated its customers, listing the trading restrictions in effect because of the
    ongoing volatility. The restrictions were widely reported and were public knowledge. 10 While
    Robinhood’s purchase restrictions and limits were in place, the prices of the restricted stocks
    remained volatile, moving up and down. (See Ex. 20, Grenadier Report Exs. 1, 9 & figs. 6, 7.)
    The nine Affected Stocks selected by Plaintiffs experienced declines over the Class Period as a
    whole, but each saw intermittent increases during the Class Period. (Id. Exs. 1A-1I.) Other
    stocks on which Robinhood placed purchase restrictions and limits did not experience net
    declines. (Id.) For example, CTRM, another stock Robinhood PCOed, almost doubled in price
    during the Class Period. (See Market Activity, Nasdaq, https://www.nasdaq.com/market-
    activity.)

    IV.        NAMED PLAINTIFFS’ TRADING PRIOR TO AND DURING THE PROPOSED
               CLASS PERIOD
               A.     Named Plaintiffs Were Aware of Co-ordinated Trading on Social Media and
                      Possible Short Squeezes.
               All but two Named Plaintiffs bought shares in one or more of the Affected Stocks on
    January 27, 2021, the final day before the Class Period, at the height of the social media craze.
    (See Dkt. Nos. 366-3, 527-1; Ng 43:21-44:18; Nguyen 66:10-69:22.) Five Named Plaintiffs
    bought AMC, four bought each of GME and BB, two bought NOK and one bought EXPR. (Id.)
    None purchased BBBY, KOSS, TR or TRVG.
               Many Named Plaintiffs testified that, rather than believing in the fundamental value of
    the companies issuing the Affected Stocks, they were aware of potential short squeezes and
    purchased the Affected Stocks hoping to profit from these short squeezes. For example,
    Abraham Huacuja testified that he purchased shares of AMC and NOK on January 27, 2021,
    without looking into the fundamentals of the companies, because “they were being shorted an
    incredible amount” and he was “banking” on there being a short squeeze that he hoped would
    generate a profit on these short-term investments. (Ex. 8, Huacuja 29:15-30:11, 42:14-46:13,
    54:4-13 ; Ex. 25, P00002064 at -2067-2068.) Brian Harbison likewise admitted that he was
    aware of and “interested in potentially participating in an attempted short squeeze of AMC.”
    (Ex. 7, Harbison 52:12-57:18.) Sandy Ng, who is not a Robinhood customer and lives in
    Canada, testified that he originally bought GME based on the potential for a short squeeze. (Ex.
    11, Ng 25:16-21, 51:24-54:2.) Cecilia Rivas testified that during this period, she actively
    followed discussions about short squeezes on WallStreetBets, and “a short squeeze would mean
    that the price of a stock is driven beyond what it’s really worth.” (Ex. 14, Rivas 27:24-28:14,
    56:11-17.) Both Ms. Rivas 11 and Mr. Ng held their shares of GME during the Class Period on
    the belief that the short squeeze was ongoing and had not yet reached its peak. (Ex. 23, Dep. Ex.
    81 (“The squeeze hasn’t squoze yet.”); Ex. 11, Ng 71:17-72:3, 83:11-20 (holding out for a
    “gamma squeeze”).). 12

          11
          Ms. Rivas also testified that she held her single GME share as a form of “social activism”
    and because investing is entertaining to her. (Ex. 14, Rivas 91:15‐91:19, 97:9-13; 160:14-19.)
          12
           A few Named Plaintiffs, by contrast, denied knowledge of possible short squeezes. Doi
    Nguyen, for instance, purported to recall virtually nothing regarding the January and February
    2021 timeframe; he testified he did not recall discussions about any possible short squeeze,



                                                       9
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 17 of 45




           Numerous Named Plaintiffs admitted to reading or posting on social media during the
    meme stock events. Brendan Clarke, for instance, testified that he checked WallStreetBets
    multiple times a day during this period. (Ex. 5, Clarke 107:21-108:6.) Thomas Cash was also
    active on WallStreetBets, which he described as a “frat house of degenerate gamblers.” (Ex. 3,
    Cash 150:6-17) Similarly, Mr. Huacuja and Mr. Nguyen testified that they perused relevant
    social media posts prior to the Class Period. (Ex. 8, Huacuja 62:11-19 (discussing review of
    social media in the weeks before the Class Period); Ex. 12, Nguyen 46:5-47:2 (admitting he saw
    on social media that AMC stock price was rising prior to the Class Period).) Mr. Ng testified
    that he did not conduct any research before investing in GME, and based all of his GME trading
    decisions on Keith Gil’s social media posts. (Ex. 11, Ng at 44:19-45:5.)
           Other Named Plaintiffs tried to distance themselves from their participation in this social
    media frenzy, even though they engaged repeatedly on various platforms regarding the meme
    stock events in the days leading up to and during the Class Period. For instance, Ava Bernard
    tweeted repeatedly in early 2021 (see, e.g., Ex. 1, Bernard 127:23-128:12), including tweets in
    which Ms. Bernard stated that retail trading was “speculati[on]” (Ex. 47, Dep. Ex. 110), that she
    wanted to “send[] a message” with her trading (Ex. 48, Dep. Ex. 111) and that AMC was being
    heavily shorted (Ex. 46, Dep. Ex. 104), despite testifying that she could not recall what her
    tweets meant. Additionally, Marcel Poirier (who lives in Canada and was not a Robinhood
    customer) testified that he did not create a Reddit account until after Robinhood imposed
    restrictions and did not know what WallStreetBets was. (Ex. 13, Poirier 55:6-12.) According to
    Reddit, however, Mr. Poirier created a Reddit account on January 15, 2021 (Ex. 49, Dep.
    Ex. 125), and commented on WallStreetBets that day. (Ex. 50, Dep. Ex. 126.) Mr. Poirier also
    denied being aware of possible short squeezes or social media frenzy about BB, despite tweeting
    about those very issues. (Ex. 13, Poirier 105:3-9; Ex. 51, Dep. Ex. 133; Ex. 52, Dep. Ex. 145.)
           B.      Named Plaintiffs’ Investment Strategies (or Lack Thereof).
           Most Named Plaintiffs testified that they conducted little to no research in connection
    with their investments, and instead traded on their “gut” or based on “momentum” or “price
    movements.” (See, e.g., Ex. 14, Rivas 45:12-18 (conceding she did not review SEC filings,
    earning announcements or cash flow projections before investing, nor did she have any real

    contemporaneous market conditions or the reasons for his trades in the Affected Stocks. (Ex. 12,
    Nguyen 30:20-32:10, 38:20-39:3; 52:17-53:16.)


                                                    10
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 18 of 45




    investing strategy); Ex. 12, Nguyen 28:4-30:8 (testifying he trades at random, based on gut
    feeling and previous price movements); Ex. 7, Harbison 34:15-35:25 (testifying to trading based
    on stock price graphs and trend lines); Ex. 6, Gurney 52:22-53:15 (testifying that he does not
    research potential investments, keep up to date with stock market news or consider earnings);
    Ex. 11, Ng 54:7-10 (testifying that he did not conduct his own GME research).) Indeed, Mr.
    Clarke conceded that he purchased GME on January 27, 2021, based on “momentum” even
    though he “didn’t really think that it was a fair value” for the stock because he did not believe the
    fundamentals of the company were strong. (Ex. 5, Clarke 40:18-20, 56:24-57:5, 77:19-22.)
           Lead Plaintiff Laine-Beveridge also testified that he makes investment decisions based on
    “gut” and does not review SEC filings before investing in a company. (Ex. 9, Laine-Beveridge
    59:8-11.) With respect to his investments in AMC and NOK, he conceded that he did not
    research the financials or business metrics of either company prior to investing; instead, he
    traded based on momentum of the Affected Stocks. (Id. 58:12-59:7.) In Mr. Laine-Beveridge’s
    opinion, any class members who bought shares of the Affected Stocks based on social media
    (and he assumed some did) were plainly following a different investment strategy than him—one
    that he believed was “probably not going to work.” (Id. 100:23-104:16.)
           C.      Named Plaintiffs Were Aware of the Robinhood Restrictions When They
                   Sold Their Shares.
           All but one of the Named Plaintiffs admit they knew about Robinhood’s trading
    restrictions when they sold their shares during the Class Period. (See Ex. 9, Laine-Beveridge
    121:11-17; Ex. 3, Cash 184:18‐22; Ex. 8, Huacuja 94:6-19; Ex. 5, Clarke 110:24-111:12; Ex. 7,
    Harbison 152:5-17; Ex. 6, Gurney 87:22-25; Ex. 13, Poirier 151:19-153:2; Ex. 14, Rivas 99:16-
    22; Ex. 1, Bernard 154:22-155:5; Ex. 2, Bohórquez 143:13-21; Ex. 12, Nguyen 89:21-23.) Mr.
    Ng (a non-Robinhood customer) is the only exception, but he later admitted to learning of
    trading restrictions imposed by another broker on January 28, days prior to his Class Period
    sales. (Ex. 11, Ng 10:12-11:3, 75:22-76:1; see Ex. 44, Dep. Ex. 37.)
           In its order denying Robinhood’s motion to dismiss, the Court relied repeatedly on
    Plaintiffs’ allegations—which had to be taken as true at the pleading stage, but must now be
    supported by evidence—that “Plaintiffs sought to understand why Robinhood imposed the
    restrictions”, (Dkt. No. 503 at 30-31), and that “[b]elieving that the restrictions were the
    byproduct of market volatility as opposed to Robinhood’s self -interest, Plaintiffs sold their
    shares”, (id., see also id. at 43-47). Few of the Named Plaintiffs, however, were even aware of


                                                     11
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 19 of 45




    the reasons Robinhood gave for the restrictions at the time they sold (nor are they even aware
    now). Mr. Huacuja, Mr. Clarke, Mr. Harbison, Mr. Gurney and Ms. Bernard testified that they
    had no recollection of any reason that Robinhood might have given for imposing the
    restrictions. (Ex. 8, Huacuja 94:15-98:16; Ex. 5, Clarke 110:24-111:12; Ex. 7, Harbison 153:13-
    18; Ex. 6, Gurney 93:22-25; Ex. 1, Bernard 163:14-167:1.) While Mr. Laine-Beveridge—the
    individual appointed by the Court as Lead Plaintiff—knew that Robinhood stated that it
    implemented the restrictions in light of the ongoing market volatility, he admitted that he did not
    believe that any reason Robinhood gave affected stock prices. (Ex. 9, Laine-Beveridge 19:16-
    20:3, 169:14-19.) And, although Plaintiffs claim that Robinhood’s restrictions induced them to
    sell at deflated prices, six Named Plaintiffs bought shares of Affected Stocks during the Class
    Period. (Ex. 61, Ng Certification, Dkt. No. 527-1 at 18; Ex. 32, Dep. Ex. 265 at 5; Ex. 39, Dep.
    Ex. 105; Ex. 65, P00002863; Ex. 13, Poirier 191:17-192:18; Ex. 12, Nguyen 102:20-104:10.)
           D.      Several Named Plaintiffs Profited on Their Trades During the Class Period.
           Several Named Plaintiffs, including the Lead Plaintiff, profited from their sales of the
    Affected Stocks. As discussed below (see infra Section III.A), Mr. Laine-Beveridge has
    provided three PSLRA certifications; the first, filed in July 2021 with his motion for appointment
    as lead plaintiff, listed AMC and NOK trades. (See Dkt. No. 366-3 at 3.) This Court certified
    Mr. Laine-Beveridge as lead plaintiff based on his claim to have suffered the greatest net loss, as
    his losses on NOK outweighed his gains on AMC. (See Dkt. No. 420 at 5.) However, nearly
    two years later, Mr. Laine-Beveridge provided a second certification, which no longer includes
    any trades in NOK. (Compare Dkt. No. 366-3 at 2 with Dkt. No. 559-6 at 5.) When asked about
    this change, Mr. Laine-Beveridge testified that he is not a member of the proposed class as it
    relates to NOK because “one of the issues is that I didn’t lose money on Nokia during the Class
    Period.” (Ex. 9, Laine-Beveridge 164:4-165:21, 135:10-24, 147:19-148:2.) Mr. Laine-
    Beveridge similarly made money on his AMC trades. (See Ex. 41, Dep. Ex. 274.)
           Other Named Plaintiffs, specifically Messrs. Cash, Gurney and Poirier, sold for a gain
    during the Class Period. (See, e.g., Ex. 3, Cash 199:4-205:20; Ex. 6, Gurney 67:23-69:2; Ex. 26,
    Dep. Ex. 131; Ex. 27, Dep Ex. 132; Ex. 28, P00002304; Ex. 29, P0002324; Ex. 30, P00002339;
    Ex. 31, Dep. Ex. 246; Ex. 40, RHMDL00097432; Ex. 72, Dep. Ex. 141.) Mr. Ng did not time
    his sale as fortuitously. As of January 31, 2021, after the PCO had been lifted and Robinhood
    was gradually loosening restrictions, Mr. Ng had an unrealized gain of over 200% on his GME



                                                    12
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 20 of 45




    trades, yet he continued to hold based on Keith Gill’s advice, and as a result lost money. (Ex. 11,
    Ng 44:19-45:5, 52:7-19.) 13
                                           LEGAL STANDARD
             Plaintiffs “seeking to maintain a class action ‘must affirmatively demonstrate [their]
    compliance’ with Rule 23.” Comcast Corp. v. Behrend, 569 U.S. 27, 33 (2013) (quoting
    Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338, 350 (2011)). To do so, a plaintiff must prove by a
    preponderance of the evidence “that there are in fact sufficiently numerous parties, common
    questions of law or fact, typicality of claims or defenses, and adequacy of representation, as
    required by Rule 23(a).” Id. (internal quotation marks and citation omitted).
             In addition, a plaintiff must demonstrate “through evidentiary proof at least one of the
    provisions of Rule 23(b).” Id. “The Rule 23(b)(3) predominance inquiry tests whether proposed
    classes are sufficiently cohesive to warrant adjudication by representation.” Amchem Prods.,
    Inc. v. Windsor, 521 U.S. 591, 623-24 (1997) (noting the predominance requirement “is far more
    demanding” than Rule 23(a)’s commonality requirement). “[W]here members of a proposed
    class will need to present evidence that varies from member to member,” individual questions
    predominate over common questions, precluding certification. Tyson Foods, Inc. v.
    Bouaphakeo, 577 U.S. 442, 453 (2016) (internal quotation marks and citation omitted).
             To determine whether plaintiffs have satisfied Rule 23’s requirements, courts must
    conduct a “rigorous analysis” of the motion and the evidence upon which it relies. Wal-Mart,
    564 U.S. at 351. The Eleventh Circuit has explained that “class certification is an evidentiary
    question, not just an analysis of the pleadings.” Bussey v. Macon Cnty. Greyhound Park, Inc.,
    562 F. App’x 782, 790 (11th Cir. 2014). As both the Supreme Court and Eleventh Circuit have
    instructed, district courts must “probe behind the pleadings,” which may require consideration of
    the merits. Comcast, 569 U.S. at 33, 35 (quoting Gen. Tel. Co. of Sw. v. Falcon, 457 U.S. 147,
    160 (1982)) (explaining that courts must “determin[e] that Rule 23 is satisfied, even when that
    requires inquiry into the merits of the claim”); see, e.g., Wal-Mart, 564 U.S. at 351 (“[T]he class
    determination generally involves considerations that are enmeshed in the factual and legal issues

        13
           Other Named Plaintiffs profited from sales of the Affected Stocks in the days just before
    the Class Period. (See Ex. 7, Harbison 140:15‐142:6; 187:14‐188:9; 120:20-22; Ex. 14, Rivas
    67:3-11, 71:2-5.) That includes Santiago Gil Bohórquez, a resident of Colombia who is not a
    Robinhood customer, and who asked on Twitter whether he could “get into trouble” for his
    conduct. (See Ex. 24, Dep. Ex. 275 (asking about “legality of what is happening”).)

    comprising the plaintiff’s cause of action.”) (internal quotation marks and citation omitted);
    Valley Drug Co. v. Geneva Pharms., Inc., 350 F.3d 1181, 1188 n.15 (11th Cir. 2003) (“[T]he
    trial court can and should consider the merits of the case to the degree necessary to determine
    whether the requirements of Rule 23 will be satisfied.”); Kirkpatrick v. J.C. Bradford & Co., 827
    F.2d 718, 722-23 (11th Cir. 1987) (explaining that courts look beyond the pleadings “in
    determining whether a motion for class certification should be granted” and noting that “it is
    often necessary for a district court to consider, for example, a deposition of a named plaintiff”).
             Plaintiffs assert market manipulation claims under Sections 9(a)(2) and 10(b) of the
    Securities Exchange Act. Under Section 9(a)(2), a plaintiff must prove that “(1) a series of
    transactions in a security creating actual or apparent trading in that security or raising or
    depressing the price of that security, (2) carried out with scienter, (3) for the purpose of inducing
    the security’s sale or purchase by others, (4) that was relied on by the plaintiff, (5) and affected
    plaintiff’s purchase or selling price.” (Dkt. 503 (the “MTD Order”) at 16.) Section 10(b)
    “requires a plaintiff to allege (1) manipulative acts; (2) damage[;] (3) caused by reliance on an
    assumption of an efficient market free of manipulation; (4) scienter; (5) in connection with the
    purchase or sale of securities; (6) furthered by the defendant’s use of the mails or any facility of a
    national securities exchange.” (Id. at 38.)
                                               ARGUMENT
             Class certification should be denied for four reasons. Because the markets for the
    Affected Stocks were inefficient during the Class Period, Plaintiffs will be required to prove
    reliance on an individualized basis and do not satisfy predominance under Rule 23(b)(3). (See
    Part I.) Because the markets were inefficient, Plaintiffs also do not satisfy the Comcast
    requirement under Rule 23(b)(3) of showing that damages can be calculated on a classwide basis
    consistent with their theory of liability. (See Part II.) Further, Plaintiffs lack standing to bring
    certain claims, and because they are open to unique defenses, they cannot satisfy the Rule
    23(b)(3) typicality requirement. (See Part III.) Finally, the Named Plaintiffs will not adequately
    prosecute the action and substantial conflicts exist. (See Part IV.) 14




        14
             Robinhood does not dispute that Plaintiffs satisfy Rule 23(a)(1) and 23(a)(2).

    I.     PLAINTIFFS WILL BE REQUIRED TO PROVE RELIANCE ON AN
           INDIVIDUALIZED BASIS, PRECLUDING CERTIFICATION UNDER RULE
           23(b)(3).
           Reliance is an element of Plaintiffs’ Section 9(a) and 10(b) claims. See ATSI Commc’ns,
    Inc. v. Shaar Fund, Ltd., 493 F.3d 87, 101 (2d Cir. 2007) (Section 10(b) claims); Baum v.
    Phillips, Appel & Walden, Inc., 648 F. Supp. 1518, 1530 (S.D.N.Y. 1986) (Section 9(a) claims).
    Plaintiffs cannot establish classwide reliance and thus will have to prove reliance on an
    individualized basis, precluding class certification.
           In a leading case about class actions for market manipulation claims, Desai v. Deutsche
    Bank Sec. Ltd., 573 F.3d 931 (9th Cir. 2009), the Ninth Circuit held that the plaintiffs could not
    invoke a presumption of reliance and affirmed the denial of class certification. The court
    explained that reliance “establishes the causal connection between the alleged fraud and the
    securities transaction.” Id. at 939. Accordingly, “[w]hether common questions of law or fact
    predominate in a securities fraud action often turns on the element of reliance.” Erica P. John
    Fund, Inc. v. Halliburton Co., 563 U.S. 804, 810 (2011) (Halliburton I). “Whether or not
    [Plaintiffs] can rely on a presumption of reliance determines whether their putative class can
    meet the requirements of Rule 23(b)(3). For without a class-wide presumption, [Plaintiffs]
    would have to prove reliance as to each class member individually.” Desai, 573 F.3d at 940.
           The only potentially applicable path for proving reliance on a classwide basis is the
    presumption of reliance pursuant to Basic Inc. v. Levinson, 485 U.S. 224 (1988). Plaintiffs in
    this case cannot invoke the Basic presumption because the markets for the Affected Stocks were
    not efficient during the relevant time period. Presumably because Plaintiffs know they cannot
    rely on Basic, they argue in the alternative that they do not need to show reliance at all or, if they
    do, that they can rely upon the presumption of reliance in Affiliated Ute Citizens of Utah v.
    United States, 406 U.S. 128 (1972). (Mot. at 11-14, 16-21.) Plaintiffs’ arguments lack merit.
    They are required to demonstrate reliance, and they cannot invoke the “common scheme”
    doctrine or the Affiliated Ute presumption in a market manipulation case.
           A.      Plaintiffs Do Not Satisfy the Basic Presumption of Reliance.
           Securities fraud class actions for exchange-traded stocks normally satisfy the
    predominance requirement because reliance can be presumed based on the existence of an
    efficient market. But this is not a normal case. To qualify for the classwide presumption of
    reliance under Basic, Plaintiffs must prove that the markets for the Affected Stocks were


                                                     15
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 23 of 45




    efficient during the Class Period notwithstanding the social-media-driven frenzy of high prices
    and extreme volatility that was unrelated to the release of company-specific value-relevant
    information. They cannot do so.
                        1. Plaintiffs Need To Meet the Basic Requirement of Efficient Markets
                           To Satisfy Reliance on a Classwide Basis.
           In Basic, the Supreme Court recognized a rebuttable presumption of reliance where “the
    market price of shares traded on well-developed markets reflect[] all publicly available
    information.” 485 U.S. at 246; see ATSI, 493 F.3d at 100 n.4 (applying the presumption in the
    context of a market manipulation claim); Dodona I, LLC v. Goldman, Sachs & Co., 847 F. Supp.
    2d 624, 651 (S.D.N.Y. 2012) (explaining that “[i]n ATSI the Second Circuit essentially
    incorporated ‘fraud on the market’ into the standard for market manipulation by requiring that
    plaintiffs show ‘reliance on an assumption of an efficient market’”) (quoting ATSI, 493 F.3d at
    99-103). Thus, “the presumption depends upon the efficiency of the market in which the
    security trades.” Desai, 573 F.3d at 942. Accordingly, a plaintiff must show that the stock at
    issue traded in an efficient market to invoke the presumption, a presumption that the defendant
    can then rebut as to particular plaintiffs. See FindWhat Inv. Grp. v. FindWhat.com, 658 F.3d
    1282, 1310 (11th Cir. 2011). As the Eleventh Circuit explained in FindWhat, an efficient market
    “rapidly and efficiently translates public information into the security’s price.” Id. A corollary
    is that a company’s stock price typically does not move significantly (after accounting for market
    and industry returns) without new, value-relevant information regarding the company and its
    business. See id.
           Plaintiffs first try to duck this issue by arguing that “whether the markets for the Affected
    Stocks were efficient” is “a merits question not ripe for decision at class certification.” (Mot. at
    14.) But this conflates reliance on the integrity of the markets, which is an element of their
    market manipulation claims, with the Basic “fraud on the market presumption,” which is a means
    of establishing classwide reliance under Rule 23(b)(3). 485 U.S. at 247. To certify a class,
    Plaintiffs must qualify for a classwide presumption of reliance, and whether the markets for the
    Affected Stocks were efficient determines whether Plaintiffs can invoke the Basic presumption.
    Amgen Inc. v. Conn. Ret. Plans & Tr. Funds, 568 U.S. 455, 473-74 (2013).
           Plaintiffs then strain to argue that because this is a market manipulation case, “Basic
    market efficiency . . . is [not] required to prove classwide reliance.” (Mot. at 15.) That also is
    not the law. No case cited by Plaintiffs even suggests otherwise. To the contrary, courts have


                                                     16
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 24 of 45




    rejected any proposed exception for market manipulation cases. In the Desai case, the district
    court rejected a proposed exception to the Basic theory of reliance because “[c]ourt[s] may not
    presume reliance in a manipulation case if the market is not efficient.” In re GenesisIntermedia,
    Inc. Sec. Litig., No. 01-CV-9024, 2007 WL 1953475, at *8 (C.D. Cal. June 28, 2007), aff’d sub
    nom. Desai, 573 F.3d 931. The court explained that a so-called “integrity of the market” theory
    of reliance was “logically flawed because the inference of reliance is broken if the market price
    of a security does not reflect the manipulative activity.” Id. at *8; see also Desai, 573 F.3d at
    942 (noting that “[w]e are chary” of the proposed exception). Other courts agree that the
    requirement of showing market efficiency under Basic to satisfy classwide reliance applies to
    “misrepresentation and manipulation claims alike.” See Merrill Lynch Auction Rate Sec. Litig.,
    704 F. Supp. 2d 378, 394 (S.D.N.Y. 2010) (citing cases).
             Plaintiffs then misstate the applicable standard for evaluating market efficiency,
    incorrectly arguing that efficiency requires “a bona fide market, nothing more.” (Mot. at 14.) In
    support of this proposition, Plaintiffs cite Fezzani v. Bear, Stearns & Co., 716 F.3d 18, 23 n.3
    (2d Cir. 2013) (“Fezzani I”), reh’g denied, 777 F.3d 566 (2d Cir. 2015) (“Fezzani II”). (Mot. at
    14.) But that case does not support Plaintiffs’ claim that the mere existence of public trading is
    sufficient to establish efficiency for Basic purposes. In Fezzani, as in ATSI, the plaintiffs brought
    market manipulation claims on an individual basis, not as a class. Fezzani I, 716 F.3d at 20; see
    ATSI, 493 F.3d at 101. Because there were no class claims, the plaintiffs were not required to
    show that they could prove reliance on a classwide basis. As such, fraud on the market and the
    Basic presumption were not at issue. See Fezzani II, 777 F.3d at 572. Fezzani thus expressed no
    opinion on the fraud on the market presumption in a class action. Instead, the court’s statement
    that “an efficient market free of manipulation” referred to “a bona fide market ‘free of
    manipulation’” described the element of reliance for an individual investor to state a Rule 10b-5
    manipulation claim. Fezzani I, 716 F.3d at 23 & n.3. 15
             Basic sets a higher bar for class actions. In order for a fraud on the market to be possible,
    the market must incorporate all information that is relevant to the company’s value. FindWhat,



        15
            Regardless, as Robinhood establishes below, Named Plaintiffs did not rely upon any
    belief that the markets for the Affected Stocks were bona fide markets free of manipulation due
    to the extraordinary run-up of the stock prices in the days leading up to the Class Period.


                                                      17

    658 F.3d at 1310. 16 Even if some investors may be able to testify on an individualized basis to a
    belief in “a bona fide market ‘free of manipulation,’” the court cannot presume reliance on a
    classwide basis on those facts alone. Fraud on the market under Basic requires not merely a
    bona fide market, but an efficient one, meaning a market in which stock-price movements have a
    logical relationship to news about the company’s value. Put simply, the burden of showing
    reliance for every class member is higher than the burden of showing reliance for one. Fezzani
    thus does not bear on the standard Plaintiffs must meet to show classwide reliance.
                        2. Plaintiffs Fail To Meet the Basic Requirement of Efficient Markets.
             Plaintiffs have failed to establish market efficiency under the standard articulated in
    Basic. While markets for exchange-traded stocks, such as the ones at issue here, may be
    “generally efficient,” there can be aberrational periods when the markets are temporarily
    inefficient. Local 703, I.B. of T. Grocery & Food Emps. Welfare Fund v. Regions Fin. Corp.,
    762 F.3d 1248, 1255 (11th Cir. 2014); (see Ex. 16, Werner FXCM 67:22-68:3 (Plaintiffs’ expert
    agrees that it is “possible for a market to be efficient at one point in time but not another”)). That
    temporary inefficiency precluding a presumption of reliance is what happened here. To be clear,
    Robinhood does not argue that the markets for the Affected Stocks were never efficient, but
    rather that the expert analysis and facts establish that they were inefficient immediately
    preceding the Class Period as well as during the Class Period.
             First, Plaintiffs’ claim of efficiency turns entirely on the opinions of their proposed
    expert, Dr. Adam Werner. But his opinions on efficiency are of no help to class certification
    because Dr. Werner’s primary opinion is that the markets for seven of the nine Affected Stocks
    were efficient during the full year before the Class Period. 17 But that is beside the point.


        16
           Plaintiffs also contend that the Court in Halliburton Co. v. Erica P. John Fund, Inc., 573
    U.S. 258 (2014) (Halliburton II) rejected the existence of a relationship between efficiency and
    value-relevant news. (Mot. at 16 n.34.) They claim that such a relationship is necessary only
    under “fundamental” efficiency. That is incorrect. Halliburton II affirmed the efficient market
    hypothesis as articulated in the academic literature, under which a stock’s price should move in
    response to news about a company’s value. See Halliburton II, 573 U.S. at 269-73; (see Daubert
    Mot. at 10-12).
        17
           Dr. Werner does not opine that the markets for the other two Affected Stocks (KOSS and
    TR), which were lightly-traded, small-cap stocks not followed by analysts, were efficient even
    for the year leading up the Class Period. (See Mot. at 21.) Accordingly, Plaintiffs have failed to
    meet their burden to certify a class that includes people who transacted in those two stocks.


                                                      18
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 26 of 45




    Dr. Werner does not analyze whether the markets were efficient during the Class Period at
    all. (See Mot. at 16.) 18 Plaintiffs assert that “only the sale decision is relevant to seller class
    members’ reliance,” yet their expert examines the markets for the Affected Stocks only “in the
    year just before the Class Period” (i.e., when the Named Plaintiffs purchased the Affected
    Stocks, and before the sales at issue). (Id. at 4, 17 (emphasis added).) 19 Robinhood’s expert,
    Prof. Grenadier, did analyze the Class Period, and concluded that the markets for the Affected
    Stocks were inefficient (see Ex. 20, Grenadier Report § VI)—a point Dr. Werner does not
    contest. (Ex. 21, Werner Rebuttal ¶ 17; Ex. 15, Werner 31:11-17.)
             Dr. Werner’s efficiency opinions are also unreliable under Daubert even aside from the
    fact that he analyzes the wrong time period. 20 Dr. Werner performed a “news/no-news” test to
    determine whether there are more statistically significant price movements on days with news
    than days without news. (Mot. at 19.) This methodology defined the “news” days as those with
    the most articles mentioning the companies at issue, regardless of whether the articles contained
    value-relevant news. (See Daubert Mot. at 10-15.) Dr. Werner’s definition of “news,” therefore,
    improperly includes articles—common on the unusual facts of this case—about price
    movements, bubbles and squeezes, and even articles pointing out the absence of news. (See id.
    at 13.) For example, Dr. Werner classified news articles about press releases from companies
    that felt compelled to note publicly that there was no company news to support the stock-price or
    volume increases at this time, as “news” that Dr. Werner would expect would impact their stock
    price. (See Ex. 70 (Jan. 25, 2021 article about BlackBerry’s statement); Ex. 71 (Jan. 27, 2021




        18
           Plaintiffs contend that “[c]ourts recently held that two stocks at issue had traded in
    efficient markets” (Mot. at 17 n.36), but fail to mention that the courts were analyzing efficiency
    several years prior to the period at issue here. See Hawaii Structural Ironworkers Pension Tr.
    Fund, Inc. v. AMC Entm’t Holdings, Inc., 338 F.R.D. 205, 210, 217 (S.D.N.Y. 2021) (examining
    December 2016 through August 2017); Pearlstein v. BlackBerry Ltd., No. 13-cv-7060, 2021 WL
    253453, at *1, *15 (S.D.N.Y. Jan. 26, 2021) (examining March through September 2013).
        19
           Dr. Werner testified that Plaintiffs’ counsel specifically instructed him to study market
    efficiency prior to, and not during, the Class Period. (See Ex. 15, Werner 31:11-23.)
        20
            It is no wonder that Dr. Werner admitted that in more than a dozen prior cases as a class
    certification “expert,” he used a different “news/no-news” test; that he had never applied the
    methodology for the “news/no-news” test he used here; and that he began his work here using a
    different methodology and changed midstream. (Ex. 15, Werner 173:16-174:8, 227:17-22.)

    article about Nokia’s statement).) This methodology is circular, and wholly deficient under
    Daubert for the reasons articulated in Robinhood’s Daubert motion.
           Second, Robinhood’s experts have shown that information about the value of the nine
    companies at issue cannot explain the large stock-price run-up observed during this period, a
    paradigmatic example of an inefficient market. (See Ex. 20, Grenadier Report § VI.) These
    price run-ups were unprecedented; for example, GME rose from its opening price of $19 on
    January 4, 2021, to as high as $380 on January 27, 2021, an increase of approximately
    1,900%. (See Ex. 18, Fischel Report ¶¶ 9, 32.) Prof. Grenadier showed that the returns on the
    Affected Stocks were so large that an investor who held the Affected Stocks from January 21 to
    27, 2021, would have outperformed every portfolio out of a million randomly selected portfolios
    held for five trading days in the past 25 years. (See Ex. 20, Grenadier Report ¶ 80.) He also
    found that the extreme price movements were accompanied by significant increases in trading
    volume and volatility. For example, on three days during the week starting January 21, 2021,
    GME had a daily turnover ratio of more than 200%, indicating that the number of shares bought
    and sold in a single day was more than twice the number of GME shares outstanding. (Id. ¶ 94.)
           Prof. Grenadier and Prof. Fischel found that these extreme price movements were not
    associated with company-specific, value-relevant information that could explain such dramatic
    movements. (See id. § VI.B.2; Ex. 18, Fischel Report ¶ 24.) Indeed, more than half of the
    companies at issue stated publicly that they were unaware of undisclosed information or changes
    in their business conditions that would account for the price movements. (See Ex. 20, Grenadier
    Report ¶¶ 98-99.) Many of the days on which the large run-ups occurred directly prior to the
    Class Period did not contain any company news, with the only news concerning retail investor
    coordination and short squeezes, which is not value-relevant information that moves prices in an
    efficient market. (Id. ¶¶ 100-104.) Moreover, as market participants at the time recognized, the
    price increases in the Affected Stocks occurred in connection with short squeezes and
    coordinated trading, and prices were thus artificial. (See Ex. 18, Fischel Report ¶¶ 25-28.)
           As Prof. Grenadier further explains, short-sale constraints can impede market efficiency
    and exacerbate this market distortion, preventing informed investors with capital resources
    (arbitrageurs) from trading to correct mispricing, as they would in an efficient market. (Ex. 20,
    Grenadier Report ¶¶ 101, 107-111.) When arbitrageurs face coordinated trading by less
    sophisticated investors, their ability to correct mispricing can be limited in the short term,



                                                     20
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 28 of 45




    causing the market to be temporarily inefficient. (Id. ¶ 110.) Consistent with established finance
    theory, Prof. Grenadier notes that academic research has found that short squeezes impacted at
    least five of the Affected Stocks (GME, AMC, BBBY, EXPR and TR), with analysts and market
    observers attributing the price movements in the remaining stocks to short squeezes or attempted
    short squeezes, which are inconsistent with an efficient market. (Id. ¶¶ 133-136.)
             The absence of a relationship between price movements in the Affected Stocks and
    disclosure of new, value-relevant information disproves market efficiency. See FindWhat, 658
    F.3d at 1310 (“A corollary of the efficient market hypothesis is that disclosure of confirmatory
    information—or information already known by the market—will not cause a change in the stock
    price.”); In re Am. Int’l Grp., Inc. Sec. Litig., 265 F.R.D. 157, 180-81 (S.D.N.Y. 2010) (denying
    class certification for failure to prove an efficient market under Basic when “the price of [the
    relevant] bonds [was not] responsive to company-specific news”); (see Ex. 20, Grenadier Report
    ¶ 13; Ex. 17, Werner Hi-Crush 124:25-125:4 (where Dr. Werner previously testified that “if [he]
    saw all sorts of crazy stock price movements on no information, that might inform [him] that the
    stock wasn’t efficient.”)). Here, where the stock-price movements bear no relationship to news
    about the value of the at-issue companies, Plaintiffs cannot establish Basic market efficiency.
             Third, many Named Plaintiffs conceded at deposition that they believed some Affected
    Stocks were impacted by short squeezes and admitted that some Affected Stocks were mispriced
    prior to any alleged market manipulation by Robinhood. (See Statement of Facts IV.A-IV.B.)
    Mr. Clarke, for example, testified that he bought GME on January 27, 2021, at a price that he
    “didn’t really think . . . was a fair value” because he did not believe the fundamentals of the
    company were strong. (Ex. 5, Clarke 40:18-20, 124:23-125-12.) Similarly, Mr. Huacuja bought
    GME “banking on there being a short squeeze,” from which he hoped to profit. (Ex. 8, Huacuja
    29:15-30:11.) 21 For these Plaintiffs, who understood the markets for the Affected Stocks were
    inefficient immediately prior to the Class Period, it strains credulity to believe that they suddenly
    assumed the markets became efficient on January 28 when Robinhood implemented its PCO


        21
           As one third-party investor explained when asked about news that might explain the price
    movements in the Affected Stocks: “Again, the only news was that everyone in the trading
    community and Wall Street was looking for the next GameStop,” adding “you couldn’t miss the
    news . . . every article every day from the sources I followed was about GameStop, short
    squeezes, et cetera.” (Ex. 10, Meade 94:8-23, 114:20-23.)


                                                     21
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 29 of 45




    restrictions. Even if class members could invoke such an outlandish and illogical assumption, all
    but one Named Plaintiff testified that they knew about Robinhood’s restrictions when they sold
    their shares of the Affected Stocks during the Class Period. (See Statement of Facts IV.C.)
    Thus, even on Plaintiffs’ theory that these restrictions manipulated the market, Plaintiffs
    willingly traded on an understanding that the market was not efficient at this time.
           In sum, Plaintiffs quote Basic, asking, “Who would knowingly roll the dice in a crooked
    crap game?” (Mot. at 16.) But that is precisely what Named Plaintiffs and other retail investors
    did here. They bought shares in the Affected Stocks, knowing the prices were distorted by a
    social media craze and attempted short squeezes. All twelve Named Plaintiffs bought on January
    27, 2021, at the peak of the market distortion, hoping to make money from timing their trades
    before the bubble burst. It is hard to imagine a group of investors who relied on the efficiency of
    the market less than the putative class here. This not only precludes Plaintiffs from invoking the
    Basic presumption as to the class, but also establishes that Robinhood has rebutted the Basic
    presumption with respect to each Named Plaintiff. See Halliburton II, 573 U.S. at 276 (holding
    defendants may, under Basic, “rebut the presumption of reliance with respect to an individual
    plaintiff by showing that he did not rely on the integrity of the market price in trading stock.”).
    Robinhood’s evidence “severs the link between the alleged” manipulation and Plaintiffs’ trading
    decisions, and thus “rebut[s] the presumption of reliance.” Basic, 485 U.S. at 248.
           For each of these reasons, Plaintiffs cannot rely on the Basic presumption, individual
    issues of reliance predominate, and a class cannot be certified under Rule 23(b)(3).
           B.      The “Common Scheme” Exception Does Not Apply.
           Plaintiffs also assert that they do not need to show reliance because they alleged “a
    common scheme.” (Mot. at 11.) Plaintiffs contend this so-called “common scheme” exception
    applies because Robinhood communicated the same message to the public as part of a “common
    scheme.” (Id.) Plaintiffs are wrong. This doctrine does not relieve a plaintiff’s burden of
    establishing reliance in a market manipulation case, nor would it apply on the facts of this case.
           First, Plaintiffs cite no case in which a court has applied the so-called “common scheme”
    exception to a market manipulation claim; Plaintiffs’ only cases involved misrepresentation
    claims. Even when a plaintiff alleges a “comprehensive scheme to manipulate that include[s]
    collateral omissions and misrepresentations in furtherance of the scheme,” courts have refused to
    apply this doctrine in market manipulation cases. For example, in In re Merrill Lynch Auction



                                                     22
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 30 of 45




    Rate Securities Litigation, the court rejected the argument “that reliance need not be shown” in a
    case alleging a comprehensive scheme to defraud because “reliance is a required element of a
    market manipulation claim.” 704 F. Supp. 2d at 393, 398 (internal quotations omitted).
           Second, even where this supposed doctrine has been applied in misrepresentation cases,
    “it must be demonstrated that the same or substantially the same misrepresentations were made
    to the putative class.” Bruhl v. Price Waterhousecoopers Int’l, 257 F.R.D. 684, 696 (S.D. Fla.
    2008) (where all class members received monthly statements showing the investment fund’s net
    asset value (“NAV”)). Here, Plaintiffs cite alleged misrepresentations in a Robinhood blog post,
    as well as statements made by Mr. Tenev (after the market closed on January 28, which was the
    first full day of the proposed class period). (Mot. at 11.) But the record refutes the notion that
    all class members should be presumed to have seen these statements. To the contrary, many of
    the Named Plaintiffs testified that they had no idea why Robinhood imposed the PCO
    restrictions. (Ex. 8, Huacuja 94:15-98:16; Ex. 5, Clarke 110:24-111:12; Ex. 7, Harbison 153:13-
    18; Ex. 6, Gurney 93:22-25; Ex. 1, Bernard 163:14-167:1.) It is also unlikely that the tens of
    thousands of putative class members who were not Robinhood customers—many of whom might
    never have heard of Robinhood—were any more likely than the Named Plaintiffs to have seen
    the alleged misrepresentations. This is not a case in which all class members received
    documents containing the same alleged misstatements, and Plaintiffs must do more than merely
    argue that any such statements were publicly available—otherwise this supposed exception
    would eliminate the reliance element from almost all Section 10(b) cases. Cf. Kennedy v.
    Tallant, 710 F.2d 711, 715, 717 (11th Cir. 1983) (applying common scheme doctrine when
    defendants failed “to disclose material facts in the [relevant] prospectuses,” which every class
    member received (as prospectus delivery was legally required before a purchase)).
           Third, to qualify for the “common scheme” exception, Plaintiffs must establish that the
    alleged misstatements “were of such a nature that it can be presumed that all members of the
    class relied upon them either to invest in the first instance, to remain in the investment, or to
    redeem their interest in the investment.” Bruhl, 257 F.R.D. at 696 (emphasis added). Plaintiffs
    cannot possibly demonstrate that the alleged misstatements regarding the reasons for
    Robinhood’s restrictions are “of such a nature that it can be presumed that all class members
    relied upon them” in making their investment decisions (such as the funds’ NAV in Bruhl) (id.),
    when the Named Plaintiffs’ testimony demonstrates that even they did not rely on Robinhood’s



                                                      23
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 31 of 45




    stated reasons for the restrictions in deciding whether to trade or were completely unaware of the
    reasons. (See Statement of Facts IV.C, IV.D (recounting Lead Plaintiff’s testimony that the
    reasons did not matter and Named Plaintiffs’ lack of awareness of the reasons).)
             Fourth, courts only apply this doctrine in misrepresentations cases where—unlike here—
    the securities at issue are “not traded on the open market.” Kirkpatrick, 827 F.2d at 723
    (emphasis added). When “securities . . . are openly traded,” a plaintiff can attempt to leverage
    the “traditional fraud-on-the-market” theory, in which “plaintiffs[] rel[y] on the integrity of an
    open and developed market to set a price accurately reflecting the security’s value.” Id. In the
    absence of a public market, plaintiffs may be able to satisfy reliance when the defendant
    “engaged in a common course of conduct” of fraudulent misrepresentation “by affirmative acts
    and by omission.” Id. at 724. Here, however, the Affected Stocks were traded on “an open and
    developed market,” and thus the common scheme exception does not apply. Id. at 723.
             Fifth, as discussed above, many of the Named Plaintiffs—as well as other putative class
    members—affirmatively “disclaim[ed] th[e] notion” that they relied on an assumption of market
    efficiency in the days leading up to the Class Period, when they purchased their shares of the
    Affected Stocks. In re GenesisIntermedia, Inc. Sec. Litig., 232 F.R.D. 321, 333 (D. Minn. 2005)
    (denying class certification where plaintiffs alleging market manipulation bought shares knowing
    the stock was mispriced, reasoning this was “at odds with Plaintiffs’ theory of reliance”). 22
    Many Named Plaintiffs purchased the Affected Stocks on January 27, 2021, for reasons
    completely divorced from the fundamental value of the underlying companies, including because
    they wanted to profit from short squeezes or thought the stocks were mispriced due to the social
    media craze. (See, e.g., Ex. 8, Huacuja 44:18-19; Ex. 5, Clarke 40:18-20.) These class members
    did not rely on the integrity of the market price when they purchased, and it blinks at reality to
    suggest that they began to assume the market had suddenly become efficient the following day
    and relied on it. (See, e.g., Ex. 23, Dep. Ex. 81 (Rivas continued to hold her share of GME
    during the Class Period when she posted: “The squeeze hasn’t squoze [sic] yet.”); Ex. 11, Ng
    71:17-72:3, 83:11-20 (Ng continued holding GME in the hopes of a “gamma squeeze”).)

        22
           The Eighth Circuit denied leave to appeal the denial of class certification. On remand, the
    court transferred the case to the Central District of California, where the district court likewise
    denied class certification on the grounds that “the market for Genesis stock was not efficient,”
    and plaintiffs could not create any exception thereto. GenesisIntermedia, 2007 WL 1953475, at
    *6. The Ninth Circuit affirmed. Desai, 573 F.3d at 931.

             C.     The Affiliated Ute Presumption Does Not Apply.
             Plaintiffs’ final argument to satisfy predominance is that they can rely upon the
    presumption of reliance under Affiliated Ute. (Mot. at 11.) But this presumption does not apply
    to market manipulation claims. See Desai, 573 F.3d at 940 (plaintiffs alleging market
    manipulation “cannot avail themselves of the Affiliated Ute presumption” permitted in omission
    cases). That is because “manipulative conduct has always been distinct from actionable
    omissions”: omission claims “stem from the failure to disclose accurate information relating to
    the value of a security where one has a duty to disclose it,” whereas manipulation involves
    “activities designed to affect the price of a security artificially by simulating market activity that
    does not reflect genuine investor demand.” Id. at 940-41. For this reason, “[i]f such
    nondisclosure of a defendant’s fraud was an actionable omission, then every manipulative
    conduct case would become an omissions case.” Id. at 941; see Rabin v. Nasdaq OMX PHLX
    LLC, 712 F. App’x 188, 194 (3d Cir. 2017) (explaining that “if nondisclosure of
    manipulation itself justified a presumption under Affiliated Ute,” it “would expand the reach of
    the securities laws beyond their intended boundaries”).
             Plaintiffs cite In re Barclays Liquidity Cross & High Frequency Trading Litigation, 390
    F. Supp. 3d 432, 449 (S.D.N.Y. 2019), in which a district court permitted the use of the Affiliated
    Ute presumption. (Mot. at 13.) That case does not apply because the manipulative scheme there
    “involve[d] primarily omissions,” rather than misrepresentations. See Barclays, 390 F. Supp. 3d
    at 448 & n.10 (discussing defendant stock exchanges’ failure to disclose information regarding
    their co-location services and proprietary feeds in required SEC filings); City of Providence v.
    BATS Glob. Mkts., Inc., 878 F.3d 36, 49-52 (2d Cir. 2017) (earlier decision in same case
    establishing that it primarily involved omissions). Here, by contrast, Plaintiffs have alleged
    misrepresentations (the Robinhood blog post and Mr. Tenev’s CNBC interview) to support their
    manipulation claims, and the Eleventh Circuit has held the Affiliated Ute presumption does not
    apply in this context. See, e.g., Cavalier Carpets, Inc. v. Caylor, 746 F.2d 749, 756 (11th Cir.
    1984) (“This Circuit has recognized the limited reach of the [Affiliated] Ute presumption,
    applying it only in primarily omission cases in which a duty to disclose existed.”). 23

        23
           Plaintiffs’ reliance on Spicer v. Chicago Bd. Options Exch., Inc.—which did not even
    discuss Affiliated Ute—is misplaced. No. 88-cv-2139, 1990 WL 16983 (N.D. Ill. Jan. 31, 1990).
    In Spicer, the claims were “based on alleged omissions” by the Chicago Board Options

               Although Plaintiffs try to recast the alleged deceptive conduct here as involving
    omissions so as to try to fit under Affiliated Ute (see Mot. at 12), they cannot get around the fact
    that their central allegations concern Robinhood’s purported misrepresentation that its
    restrictions were attributed “solely to ‘market volatility’” (id. at 11-12 (Robinhood “announced
    in a blog post that it had placed the Affected Stocks into PCO, ‘in light of recent market
    volatility’”)). Indeed, in concluding that Plaintiffs plausibly pleaded manipulative conduct
    sufficient to withstand a motion to dismiss, the Court focused on the alleged misstatement that
    “Robinhood outright denied having a liquidity issue and blamed market volatility exclusively.”
    (MTD Order at 45.) As such, the alleged manipulation here depends primarily on
    misrepresentations, and the Affiliated Ute presumption does not apply. 24
               In any event, like all presumptions, the Affiliated Ute presumption is rebuttable, and
    Robinhood has done so with overwhelming evidence that “Plaintiffs did not rely on the
    omissions at issue in making their investment decisions.” Barclays, 390 F. Supp. 3d at 449
    (internal quotations omitted). As described above, most of the Named Plaintiffs did not recall
    any reason Robinhood provided for its restrictions. And Lead Plaintiff Blue Laine-Beveridge
    testified he did not believe the reasons Robinhood gave affected the price. (See Statement of
    Facts IV.C.) As such, they could not have relied on the alleged omission—that Robinhood
    imposed the restrictions because of liquidity issues—in making their investment decisions.
               For the foregoing reasons, Plaintiffs are not entitled to a classwide presumption of
    reliance on any of their legal theories, and class certification must be denied.
    II.        PLAINTIFFS WILL BE FORCED TO LITIGATE DAMAGES ON AN
               INDIVIDUALIZED BASIS, PRECLUDING CERTIFICATION UNDER RULE
               23(b)(3).
               The Court should deny class certification for the independent reason that Plaintiffs have
    not shown that they will be able to offer a damages model that can withstand scrutiny under


    Exchange (“CBOE”). Id. at *14. Moreover, the class in Spicer was limited to individuals who
    traded on the CBOE. Id. at *16. Here, the majority of putative class members did not trade on
    Robinhood, making it even more farfetched to presume that they relied on any purported
    omission regarding the reasons for restrictions implemented on that platform.
          24
           Plaintiffs assert that Affiliated Ute applies because they should be able to assume that a
    market is free from manipulation. (Mot. at 12.) However, such an approach would “very nearly
    render the reliance element of private 10(b) claims a nullity.” Rabin v. Nasdaq OMX PHLX
    LLC, 182 F. Supp. 3d 220, 246 (E.D. Pa. 2016), aff’d, 712 F. App’x 188 (3d Cir. 2017).

    Comcast. To satisfy Rule 23(b)(3)’s predominance requirement, Plaintiffs must establish that
    their damages are measurable on a classwide basis using a common methodology that is
    consistent with their liability theory and measures only damages attributable to that theory.
    Comcast, 569 U.S. at 35. “If the model does not even attempt to do that, it cannot possibly
    establish that damages are susceptible of measurement across the entire class for purposes of
    Rule 23(b)(3).” Id. Further, the proposed methodology cannot be based on “speculative”
    inferences because “[s]uch a proposition would reduce Rule 23(b)(3)’s predominance
    requirement to a nullity.” Id. at 35-36.
            As courts in this Circuit have explained, Comcast “instructed lower courts to conduct a
    ‘rigorous analysis’ to determine whether the purported damages model fits the liability case.”
    Randolph v. J.M. Smucker Co., 303 F.R.D. 679, 696-97 (S.D. Fla. 2014); see Krukever v. TD
    Ameritrade, Futures & Forex LLC, 328 F.R.D. 649, 662 (S.D. Fla. 2018) (denying class
    certification when it was “simply impossible” to “[c]alculat[e] damages using ‘readily available’
    data and a plug-and-chug formula, as Plaintiffs suggest[ed] . . . without conducting complex and
    fact specific inquiries to determine the proper and accurate data to plug into the
    formula”). Without such an analysis, a plaintiff’s “bald, unsupported assertion that [their]
    method will work” is insufficient. Randolph, 303 F.R.D. at 698.
            Plaintiffs’ damages theory is founded on the premise that the “closing price on January
    27” is “the fair value of what [class members] would have received” absent Robinhood’s
    restrictions, and that consequently “[d]amages can be computed as the difference between the
    closing price on January 27 and the sales price class members received during the Class Period.”
    (Mot. at 22, 3-4.) There is no evidentiary support for that premise. In the week leading up to the
    Class Period, the Affected Stocks experienced price increases of up to 1,591%. (Ex. 20,
    Grenadier Report, fig. 2.) As explained by Prof. Grenadier and Prof. Fischel, the Affected
    Companies’ price movements during that week could not be explained by value-relevant news.
    (Id. App’x E; Ex. 18, Fischel Report App’x D.) The closing price on January 27 for the Affected
    Stocks was therefore completely untethered from any “fair value”—a fact to which Named
    Plaintiffs testified at deposition (see, e.g., Ex. 5, Clarke 40:18-20 (testifying that the price of
    GME at this time did not reflect the company’s fundamentals))—and to which some of the
    companies issuing the Affected Stocks agreed (see, e.g., Ex. 42, BlackBerry Press Release,
    Jan. 25, 2021; Ex. 57, Nokia Press Release, Jan. 27, 2023).



                                                       27
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 35 of 45




             Plaintiffs attempt to rescue their damages methodology by arguing that “price is the best
    proxy for value.” (Mot. at 25.) But the sources they cite make clear that price is a proxy for
    value only in an efficient market. As Plaintiffs quote, “if markets are informationally
    efficient, . . . professional active managers should do no better at picking stock portfolios than
    monkeys with darts” (Mot. at 25 (quoting Ex. 68, Cochrane, Eugene Fama, Efficient Markets,
    and the Nobel Prize) (emphasis added)), because prices in an efficient market are a good
    indicator of a stock’s fair value. (See also Plf. Ex. 34, Fischel, Efficient Capital Markets 914-15
    (tying the use of price as a proxy for value to the existence of efficiency).)
             As discussed, Robinhood has provided ample evidence that the markets for the Affected
    Stocks were not efficient on January 27, 2021. Plaintiffs, by contrast, have proffered no
    evidence that the closing prices on January 27, 2021, were the result of efficient markets. As
    explained above and in Robinhood’s Daubert motion, Dr. Werner applies the wrong efficiency
    standard and tests for that standard using two unreliable analyses that neither he nor anyone in
    his field has used before. (Daubert Mot. at 10-14, 16-17.) Moreover, his full-year analysis is so
    overbroad as to provide no information on the question at hand for Comcast purposes—the
    efficiency of the market on the last day of that year, which Dr. Werner excluded from his
    regression model because of “potentially abnormal returns” on January 27. (See id. at 9.) His
    opinions are inadmissible under Daubert. (Id. at 7-10.) Because Plaintiffs have provided no
    admissible—much less convincing—evidence that the markets for the Affected Stocks were
    efficient on January 27, 2021, they have failed to support the premise of their supposed
    classwide damages methodology, and so “have not satisfied their burden to show that this
    method of calculating damages for this class is reliable or an appropriate fit to the theory of
    injury here.” Cardenas v. Toyota Motor Corp., No. 18-CV-22798, 2021 WL 6926418, at *21
    (S.D. Fla. Aug. 12, 2021). 25
             Moreover, Plaintiffs have not offered a damages model that could show but-for prices
    (where the Affected Stocks would have traded absent Robinhood’s restrictions) during the Class
    Period because they have not even attempted to show efficiency during the Class Period.
    (Ex. 15, Werner 31:11-17.) In an inefficient market, stock-price movement may have no relation


        25
          While Plaintiffs complain that Robinhood “provide[s] no viable alternative” of measuring
    damages (Mot. at 25), it is their burden, not Robinhood’s. See, e.g., Ulysse v. Waste Mgmt. Inc.,
    No. 11-CV-80723, 2013 WL 11327137, at *3 (S.D. Fla. Sept. 13, 2013).

    to new information. (See Ex. 20, Grenadier Report ¶¶ 167-168; Ex. 18, Fischel Report ¶ 38.)
    And in an ongoing short squeeze, it is inevitable that prices will fall at some point. (Ex. 18,
    Fischel Report ¶¶ 27-28.) Plaintiffs’ assertion that “[a]t minimum, the closing price on January
    27 is what class members would have received” during the Class Period lacks any foundation
    because there is no reasonable or reliable means to measure what might have happened, and
    when the bubble would inevitably have burst, in their “but for” world. (Mot. at 22.) Without an
    efficient market, there can be no “reasonably certain proof of damages” (see Ex. 56, Ferrillo et
    al. 122-23), and Plaintiffs cannot proffer a classwide damages methodology.
    III.        BECAUSE PLAINTIFFS LACK STANDING OR ARE ATYPICAL AND
                SUBJECT TO UNIQUE DEFENSES, THEY CANNOT SATISFY RULE 23(a)(3).
                Class certification should also be denied for three further independent reasons because
    the claims and defenses are not typical as required under Rule 23(a)(3).
                A.     A Class Cannot Be Certified with Laine-Beveridge as Lead Plaintiff.
                To assert claims on behalf of a class, a proposed representative must have standing to
    assert individual claims. O’Shea v. Littleton, 414 U.S. 488, 493-94 (1974); see also Cuban Am.
    Bar Ass’n, Inc. v. Christopher, 43 F.3d 1412, 1423 (11th Cir. 1995). Mr. Laine-Beveridge lacks
    standing to assert securities claims against Robinhood.
                The Court appointed Mr. Laine-Beveridge as lead plaintiff based on his claimed losses in
    NOK. His original PSLRA certification, filed with his motion for appointment as lead plaintiff,
    listed AMC and NOK trades. (Dkt. No. 366-3 at 2.) In ruling on the lead plaintiff motion, this
    Court noted that Mr. Laine-Beveridge lacked standing to pursue claims related to his AMC
    transactions because he profited on them. (Dkt. No. 420 at 9.) The Court nevertheless appointed
    Mr. Laine-Beveridge as lead plaintiff on the basis that he claimed to have suffered the greatest
    net loss among the applicants to be lead plaintiff due to his transactions in NOK. (Id. at 5.)
                After the Court’s appointment Order, however, Plaintiffs’ counsel amended the class
    definition to include only individuals who sold the Affected Stocks at a loss “between January 28
    to February 4, 2021.” (See Dkt. No. 527 at 1.) 26 This amendment meant Mr. Laine-Beveridge
    was no longer a class member with respect to his transactions in NOK, as all of his NOK sales


           26
          In the lead plaintiff motion, The Rosen Law Firm defined the proposed class as persons
    “who sold any of the Affected Securities . . . via the Robinhood trading platform on or after
    January 28, 2021 as a result of Robinhood’s restrictions.” (Dkt. No. 366-0 at 1.)


                                                        29
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 37 of 45




    occurred on or after February 22, 2021. (Dkt. No. 366-3 at 2.) As a result, Plaintiffs’ counsel
    produced a second PSLRA certification from Mr. Laine-Beveridge dated April 14, 2023, days
    before his deposition, which no longer included any transactions in NOK, and also revised his
    reported transactions in AMC. (See Ex. 33, P00002834.) When asked at his deposition,
    Mr. Laine-Beveridge could not confirm which certification was accurate. (See Ex. 9, Laine-
    Beveridge 164:4-165:21.) He was able to confirm however, that under the amended class
    definition he is not a member of the proposed class as it relates to NOK because “one of the
    issues is that I didn’t lose money on Nokia during the Class Period.” (Id. 135:10-24.)
             Thus, the basis for the Court’s appointment of Mr. Laine-Beveridge as lead plaintiff—his
    NOK transactions—has evaporated. Nor can he serve as lead plaintiff based on his AMC
    transactions, from which he profited. (Dkt. No. 420 at 9.) While Plaintiffs’ counsel may now
    contend that Mr. Laine-Beveridge lost money if the Court examines only his AMC sales during
    the Class Period, any such loss is relatively small. (Compare Dkt. No. 366-3 (reporting overall
    AMC gain of $12,443.51) with Dkt. No. 559-6 (reporting loss of $2,960.17 by omitting sales on
    June 15, 2021).) Other lead plaintiff applicants claimed greater losses in the Affected Stocks.
    (See Dkt. No. 365 at 8-9 (competing movants alleging total losses of $16,239.70).) Before
    certifying a class, the Court would therefore need to reopen the lead plaintiff process. See, e.g.,
    In re Allergan PLC Sec. Litig., No. 18-cv-12089, 2021 WL 4077942, at *1, *5 (S.D.N.Y. Sept. 8,
    2021) (appointing new lead plaintiff and new lead counsel after having denied class certification
    on the basis of original lead plaintiff’s inadequacy).
             Moreover, even if, contrary to the Court’s prior ruling, Mr. Laine-Beveridge had standing
    due to his AMC transactions during the Class Period, he would nevertheless be an atypical class
    representative because his overall profit on his AMC transactions subjects him to unique
    defenses. Rule 23(a)(3) precludes class certification where a putative class representative is
    subject to unique defenses that threaten to become the focus of the litigation. 27 See City Pension
    Fund for Firefighters & Police Officers in Miami Beach v. Aracruz Cellulose S.A., No. 08-cv-
    23317, 2009 WL 10664427, at *5 (S.D. Fla. Aug. 7, 2009). That an investor has “suffer[ed] no

           Because the typicality and adequacy analyses “tend to overlap,” many of the arguments
    articulated regarding typicality apply with equal force with respect to adequacy. Appleyard v.
    Wallace, 754 F.2d 955, 958 (11th Cir. 1985).


                                                     30
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 38 of 45




    net losses” is one such defense. 28 Regions, 762 F.3d at 1259 (citing In re Comdisco Sec.
    Litig., 150 F. Supp. 2d 943, 945-46 (N.D. Ill. 2001)).
             B.     Named Plaintiffs Did Not Rely on the Integrity of the Market.
             Where a putative class representative’s reliance on the integrity of the market may be
    challenged, that also renders them atypical. There is substantial evidence that Named Plaintiffs
    did not rely on the integrity of the market. First, Named Plaintiffs have conceded facts showing
    that they did not rely on the integrity of the market when they purchased the Affected Stocks.
    Second, the Court may infer from Named Plaintiffs’ trading strategies that they did not rely on an
    assumption of market efficiency. A class cannot be certified with these Named Plaintiffs.
             Plaintiffs alleging market manipulation “may be subject to unique defenses regarding
    their reliance on the integrity of the market” when they traded “in reliance on [their]
    understanding that the market did not accurately price the stock at the time,” as this directly
    “calls into question their suitability as class representatives.” GenesisIntermedia, 232 F.R.D. at
    329; see Kirkpatrick, 827 F.2d at 723 (noting that “district courts have denied class certification
    for fraud-on-the-market claims where evidence indicates that the named plaintiffs may in fact
    have relied on factors other than the market’s integrity”). Here, as explained in Statement of
    Facts IV.C, the Named Plaintiffs admitted they knew about brokerage trading restrictions at the
    time they sold their shares of the Affected Stocks during the Class Period. Thus, Plaintiffs
    willingly traded “in reliance on [their] understanding that the market did not accurately price the
    stock at the time.” GenesisIntermedia, 232 F.R.D. at 329.
             Nor can Plaintiffs claim they relied on Robinhood’s statements regarding the reasons for
    the restriction: few of the Named Plaintiffs even recalled receiving or viewing any statement
    regarding why Robinhood imposed the restrictions. (See Statement of Facts IV.C.) One of the
    few who did, Mr. Laine-Beveridge, testified that he did not think Robinhood’s reasons had
    anything to do with the stock-price decline. (Ex. 9, Laine-Beveridge at 169:14-20.) Because
    Named Plaintiffs did not rely on Robinhood’s statements about the reasons for the restrictions in
    deciding to sell their shares, they are atypical of any class that could pursue viable claims. See


        28
           Two other Named Plaintiffs—Cash and Poirier—profited on their sales of Affected Stocks
    during the Class Period. See supra at 12-13. Those Named Plaintiffs are therefore also atypical.
    See Katz v. Comdisco, Inc., 117 F.R.D. 403, 407-08 (N.D. Ill. 1987) (holding atypical claims of
    class representative who profited on transactions during class period).

    Underwood v. Lampert, No. 02-cv-21154, 2005 WL 8155010, at *4 (S.D. Fla. Sept. 9, 2005)
    (plaintiff atypical when he “did not believe that the market was defrauded during the class
    period,” as this “strike[s] at the core of the ‘fraud on the market’ theory and threaten[s] the
    common claim of the class”).
             Unusual trading strategies and habits separately indicate that a plaintiff will “face[] []
    unique defenses concerning their lack of reliance on . . . the integrity of the market.” Landry v.
    Price Waterhouse Chartered Accountants, 123 F.R.D. 474, 475-76 (S.D.N.Y. 1989). Plaintiffs
    argue that Named Plaintiffs’ investment strategies and reasons for their trades in the Affected
    Stocks are irrelevant. (See Mot. at 9.) 29 This is not so. See, e.g., Luczak v. Nat’l Beverage
    Corp., 548 F. Supp. 3d 1256, 1267-68 (S.D. Fla. 2021) (“Plaintiff’s haphazard and highly
    unusual trading practices—which are anything but typical—give rise to unique defenses . . . .”);
    Bang v. Acura Pharm. Inc., No. 10-cv-5757, 2011 WL 91099, at *6 (N.D. Ill. Jan. 11, 2011)
    (“unusually high-volume and high frequency trading can raise challenges to typicality”).
             In Luczak, the court concluded the plaintiff’s trading practices rendered him atypical
    when he testified at deposition that “he [did] not consider himself a sophisticated investor,” “he
    [did] not consider himself a long-term investor and [did] not recall any instance in which he held
    a stock for more than one year,” he “did not[] look at or read SEC filings of [defendant] or any
    other company in which he has invested,” and “he b[ought] and s[old] hundreds of thousands of
    dollars’ worth” of stock that he held “for periods as short as a single day, and d[id] not recall
    why he chose to buy and sell so quickly.” 548 F. Supp. 3d at 1267-68. Likewise, a plaintiff’s
    strategy to focus on “technical price movements rather than price” may render that plaintiff
    atypical, as this “rebut[s] the reliance presumption,” “even under a fraud-on-the-market theory.”
    In re Safeguard Scientifics, 216 F.R.D. 577, 582 (E.D. Pa. 2003). As summarized below, Named
    Plaintiffs exhibit these same unusual trading practices, subjecting them to unique defenses:
    •   Lack of Investing Experience and Research: Ms. Rivas and Ms. Bernard testified that they
        did not have any real investment strategy or investing experience. (Ex. 14, Rivas 43:16-20,
        120:18-20; Ex. 1, Bernard 102:20-103:18, 110:22-111:17.) Further, five of the Named
        Plaintiffs admitted that they did not research the financials or business metrics of the
        Affected Stocks in advance of trading. (See Ex. 8, Huacuja 54:4-17; Ex. 12, Nguyen 33:21-
        36:9; Ex. 14, Rivas 50:11-20; Ex. 11, Ng 54:7-10; Ex. 9, Laine-Beveridge 57-59.) Two
        Named Plaintiffs claimed they do not recall why they decided to trade. (See Ex. 12, Nguyen

        29
          Plaintiffs’ conclusory assertion that the supposed irrelevance of investment strategies and
    reasons for trading “is particularly true for a seller class” (Mot. at 9) is entirely without support.


                                                       32
Case 1:21-md-02989-CMA Document 567 Entered on FLSD Docket 06/07/2023 Page 40 of 45




        83:21-24, 107:4-16; Ex. 1, Bernard 149:5-151:13.) Taken together, the lack of research,
        investing experience and real trading strategy across the Named Plaintiffs renders them
        atypical. See, e.g., Luczak, 548 F. Supp. 3d at 1267-68.

    •   Trading Based on Price Movements and Momentum: Three Named Plaintiffs testified
        that they traded the Affected Stocks based on momentum. (Ex. 5, Clarke 73:15-74:9; Ex. 12,
        Nguyen 73:13-20; Ex. 9, Laine-Beveridge 107:25-108:5.) Mr. Harbison also testified that he
        generally trades based off momentum, selling stocks when he sees a trendline declining and
        buying when he sees a trendline increasing. (Ex. 7, Harbison 34:15-35:25.) Accordingly,
        these Named Plaintiffs are atypical of the putative class. See, e.g., Safeguard Scientifics, 216
        F.R.D. at 582 (plaintiff atypical when he traded based on “technical price movements”).

    •   Buying and Selling on the Same Day: Four Named Plaintiffs each bought and sold shares
        of the Affected Stocks on the same day during the Class Period. (See Ex. 64, P00002781
        (Ms. Bernard bought and sold shares of AMC on February 3); Ex. 65, P00002863
        (Mr. Bohórquez bought and sold shares of AMC on January 28, January 29 and February 1
        and also bought and sold shares of EXPR on January 28); Ex. 62, Jan. 9, 2023 Poirier
        Certification (Mr. Poirier bought and sold shares of BB on January 28); Ex. 61, Jan. 11, 2023
        Ng Certification (Mr. Ng bought and sold shares of GME on February 4.) This renders these
        Named Plaintiffs atypical. See Applestein v. Medivation, Inc., No. 10-cv-998, 2010 WL
        3749406, at *3 (N.D. Cal. Sept. 20, 2010) (plaintiff atypical when he “bought and sold [the
        relevant] stock on the same day” during the class period and “his trading ranged from a
        single trade to as many as 44 trades in a single day”).

    •   Investing Based on Recommendations: Mr. Ng testified that he made GME trading
        decisions based on the advice of social media influencer Keith Gill, buying GME “[b]ecause
        [he] saw a post on Reddit [by Gill] that interested him” and that he continued to hold because
        “[i]f DFV [wa]s holding, . . . I was holding.” (Ex. 11, Ng 43:12-21, 83:11-20.) 30 Courts
        have found plaintiffs like Mr. Ng atypical when they made investment decisions based on
        “recommendations from friends and associates [and] not on the statements of [the defendant]
        or the integrity of the market.” See, e.g., Landry, 123 F.R.D. at 476.

             C.     Named Plaintiffs Lack Standing To Represent Class Members Who Traded
                    in BBBY, KOSS, TR or TRVG.
             Named Plaintiffs lack standing to prosecute claims for class members who traded in four
    of the nine Affected Stocks—BBBY, KOSS, TR and TRVG—because none of the Named
    Plaintiffs suffered losses from sales of those stocks, or traded in them at all. See Teamsters
    Local 445 Freight Div. Pension Fund v. Bombardier Inc., No. 05 Civ. 1898, 2005 WL 2148919
    at *4 (S.D.N.Y. Sept. 6, 2005) (“A named plaintiff in a class action that purchased securities


        30
          Lead Plaintiff Laine-Beveridge has disclaimed the wisdom of this trading strategy. In his
    opinion, any class members who bought shares of the Affected Stocks based on social media
    were following a different investment strategy. (Ex. 9, Laine-Beveridge 100:23-104:16.)


                                                     33

    from one issuer does not have standing to bring claims on behalf of purchasers of securities from
    a different issuer.”); Luczak, 548 F. Supp. 3d at 1262-63, 1265, 1268 (same). Accordingly, to the
    extent the Court certifies a class, it cannot include these Affected Stocks. 31
               The Court appointed Mr. Laine-Beveridge as lead plaintiff even though he traded in only
    two of the nine Affected Stocks. (Dkt. No. 420 at 9.) In doing so, the Court expressly noted
    that, in this situation, “the proper solution is to simply add additional named plaintiffs.” (Id.)
    Plaintiffs failed to follow the Court’s direction, and therefore these Named Plaintiffs lack
    standing to bring claims relating to BBBY, KOSS, TR and TRVG.
               The cases cited by Plaintiffs (Mot. at 8) are inapposite. In In re Dreyfus Aggressive
    Growth Mutual Fund Litigation, No. 98-cv-4318, 2000 WL 1357509, at *10 (S.D.N.Y Sept. 20,
    2000), the court certified a class where representatives had invested in all but one of the
    defendant’s mutual funds at issue. Here, however, Plaintiffs seek to represent a class of investors
    in nine Affected Stocks issued by companies other than Robinhood, all of which are differently
    situated from one another. Dreyfus does not stand for the proposition that Plaintiffs can group all
    nine Affected Stocks as if they are a nearly fungible set of nine securities from a single issuer
    and simply conclude that “by proving their claims” as to GME that they will “necessarily prove
    the claims” as to KOSS, an entirely different stock. Id. at *5. And in Krukever, 328 F.R.D. at
    655, the plaintiffs held options on “S&P Emini futures contracts,” known as “ES options.”
    Importantly, these 888 types of ES options were not 888 different securities, but rather 888
    different put option contracts on futures of one underlying securities basket (the S&P 500). 32
    IV.        PLAINTIFFS CANNOT SATISFY RULE 23(a)(4) BECAUSE THEY WILL NOT
               ADEQUATELY PROSECUTE THE ACTION AND SUBSTANTIAL CONFLICTS
               OF INTEREST EXIST.
               The adequacy prong of Rule 23(a)(4) requires that named plaintiffs have sufficient
    “participation in and awareness of the litigation.” Kirkpatrick, 827 F.2d at 727. A class may not
    be maintained where named plaintiffs “have abdicated their role in the case beyond that of
    furnishing their names as plaintiffs.” Id. (quoting Helfand v. Cenco, 80 F.R.D. 1, 7-8 (N.D. Ill.


          31
           As noted in Part I.A, a class cannot be certified as to KOSS or TR for the independent
    reason that Plaintiffs do not even contend that those markets were efficient. (See Mot. at 18.)
          32
           Further, in Krukever, the plaintiffs brought a best execution claim for the alleged
    liquidation of options at a poor price. Unlike a best-execution claim, a securities fraud claim
    turns on price movements for each security during the class period, which will vary by security.


                                                       34

    1977)). Adequacy is also defeated when interests are actually or potentially antagonistic to, or in
    conflict with, the interests and objectives of other class members. In re Photochromic Lens
    Antitrust Litig., No. 8:10-cv-984, 2014 WL 1338605, at *14 (M.D. Fla. Apr. 3, 2014). The
    “existence of both economic winners and economic losers within the potential class” can
    “create[] a fundamental conflict precluding adequate representation of the class.” Id.
           Named Plaintiffs admit they have played virtually no role in directing the litigation. Lead
    Plaintiff Laine-Beveridge testified that he did not review the motion to dismiss briefing or the
    Court’s opinion on that motion. (Ex. 9, Laine-Beveridge 25:12-27:10.) Nor had he
    communicated with Plaintiffs’ counsel about the class certification motion (which Plaintiffs’
    counsel filed two days after the deposition) or reviewed the expert reports (which had been
    exchanged previously). (Id. 30:5-31:9.) This is inadequate as a matter of law. See Welling v.
    Alexy, 155 F.R.D. 654, 659 (N.D. Cal. 1994) (proposed representative who “ceded control to his
    lawyers” inadequate).
           Other Named Plaintiffs showed a complete lack of interest in the litigation. Mr. Gurney,
    for example, struggled to provide even basic knowledge about this case. When asked to describe
    the putative class he seeks to represent, Mr. Gurney testified that the class is comprised of
    “human beings who have a complaint.” (Ex. 6, Gurney 128:16-130:4.) Nor could he confirm
    whether he is suing on his AMC sales (on which he earned a profit). (Id. 67:23-69:2, 97:22-
    98:18.) In flagrant disregard of his obligation to dedicate attention to this case, Mr. Gurney sat
    for his deposition from the driver’s seat of his car—while driving. (Id. 6:20-7:8.)
           Named Plaintiffs’ trades in the Affected Stocks during the Class Period also establish
    substantial conflicts of interest. Mr. Cash sues on his sale of GME on January 28, the same day
    that Mr. Ng bought shares of GME. Further, despite attempting to represent a putative class of
    investors that sold shares of the Affected Stocks during the Class Period, six of the Named
    Plaintiffs bought shares of the Affected Stocks during this time. (See Statement of Facts IV.C.)
    These variations establish intraclass conflicts. See Montgomery v. New Piper Aircraft, Inc., 209
    F.R.D. 221, 226-27 (S.D. Fla. 2002) (recognizing intraclass conflict between buyers and sellers).
                                             CONCLUSION
           For the foregoing reasons, Robinhood respectfully requests that the Court deny Plaintiffs’
    motion for class certification.

                                       REQUEST FOR HEARING
           Pursuant to Local Rule 7.1(b)(2), Robinhood requests an evidentiary hearing due to the
    complexity of the legal questions raised by Plaintiffs’ motion for class certification. See
    Local Rule 7.1(b)(2) (“The Court in its discretion may grant or deny a hearing as requested, upon
    consideration of both the request and any response thereto by an opposing party.”) “Although a
    hearing is not required prior to granting or denying a motion for class certification . . . such a
    procedure may, in an appropriate case, aid the court in deciding the issue.” Hudson v. Delta Air
    Lines, Inc., 90 F.3d 451, 458 n.15 (11th Cir. 1996) (citing Grayson v. K Mart Corp., 79 F.3d
    1086, 1099 (11th Cir. 1996)); see also In re Domestic Air Transp. Antitrust Litig., 137 F.R.D.
    677, 700 (N.D. Ga. 1991) (court held “limited evidentiary hearing” regarding “appropriateness of
    class certification”). A hearing on class certification in this case would assist the Court in
    assessing the numerous legal theories concerning reliance set forth by Plaintiffs. In particular, an
    evidentiary hearing with live expert testimony concerning market efficiency would aid the Court
    in determining whether Plaintiffs may rely on the presumption of reliance established by Basic.
    Courts routinely grant class certification hearings to address these issues. See, e.g., Krogman v.
    Sterritt, 202 F.R.D. 467, 470, 478 (N.D. Tex. 2001) (rejecting Basic presumption based on
    market inefficiency after class certification hearing).
           If the Court also grants a hearing on Robinhood’s Daubert motion, Robinhood requests
    the hearings be held in conjunction. The parties’ arguments with respect to the two motions are
    closely intertwined. Accordingly, a joint hearing will provide further clarification on these
    issues and promote judicial efficiency.
