No. CV12-00555-PHX-DGC
ORDER

v.
First Solar, Inc., et al.,
Defendants.

13
14
15

This is a securities fraud class action brought on behalf of persons who purchased

16

First Solar, Inc. stock between April 30, 2008 and February 28, 2012 (the “Class

17

Period”). First Solar designs and manufactures solar panel modules, and its stock is

18

publicly traded on the NASDAQ Global Market (“NASDAQ”). Plaintiffs have sued First

19

Solar and certain of its officers and directors (collectively, “Defendants”), alleging they

20

made misrepresentations designed to inflate its stock price in violation of Sections 10(b)

21

and 20(a) of the Securities Exchange Act of 1934 (the “1934 Act”) and Rule 10b-5.

22

Plaintiffs move to certify the class. Doc. 156. The motion is fully briefed, and the

23

Court heard oral argument on September 20, 2013. For reasons stated below, the Court

24

will grant the motion.

25

I.

Rule 23 Requirements.

26

Under Rule 23(a), a district court may certify a class only if (1) it is so numerous

27

that joinder of all members is impracticable, (2) there are questions of law or fact

28

common to the class, (3) the claims of the representative parties are typical of the claims

1

of the class, and (4) the representatives will fairly and adequately protect the interests of

2

the class. Fed. R. Civ. P. 23(a)(1)-(4). The Court must also find that one of the

3

requirements of Rule 23(b) has been met. Plaintiffs rely on Rule 23(b)(3), which requires

4

that questions of law or fact common to the class predominate over any questions

5

affecting only individual class members, and that a class action be superior to other

6

available methods for resolving the controversy. Fed. R. Civ. P. 23(b)(1)-(3).

7

The Ninth Circuit has not articulated the applicable standard of proof for the

8

Rule 23 requirements, see Conn. Ret. Plans & Trust Funds v. Amgen Inc., 660 F.3d 1170,

9

1175 (9th Cir. 2011) (Amgen I), aff’d by 133 S. Ct. 1184 (2013) (Amgen II), but at least

10

four circuits have adopted a preponderance of the evidence standard, see Messner v.

11

Northshore Univ. HealthSystem, 669 F.3d 802, 811 (7th Cir. 2012); Novella v.

12

Westchester Cnty., 661 F.3d 128, 148-49 (2d Cir. 2011); Alaska Elec. Pension Fund v.

13

Flowserve Corp., 572 F.3d 221 (5th Cir. 2009); In re Hydrogen Peroxide Antitrust Litig.,

14

552 F.3d 305, 320 (3d Cir. 2008). This standard appears to be the trend in federal courts,

15

Newberg on Class Actions, § 7:21 (Sept. 2013), and “merely requires that [plaintiffs]

16

demonstrate that it is more likely than not that a particular requirement of Rule 23[] has

17

been satisfied.” Sheperd v. Babcock & Wilcox of Ohio, No. C-3-98-391, 2000 WL

18

987830, at *1 n.5 (S.D. Ohio Mar. 3, 2000). The Court concludes that Plaintiffs bear the

19

burden of establishing the Rule 23 requirements by a preponderance of the evidence.

20

Defendants agree that the requirement of Rule 23(a) are satisfied, but argue that

21

Plaintiffs cannot prove that common questions will predominate over individual issues as

22

required by Rule 23(b)(3). Doc. 161 at 5-6. Because the Court must rigorously analyze a

23

class action to ensure it comports with Rule 23, see Wal Mart Stores, Inc. v. Dukes, 131

24

S. Ct. 2541, 2551 (2011), the Court will first address the Rule 23(a) requirements.

25

II.

26

Rule 23(a).
Plaintiffs seek certification of the following class:

27
28

All persons who purchased or otherwise acquired the publicly traded
securities of First Solar, Inc. between April 30, 2008 and February 28,
-2-

1
2
3
4

2012, inclusive, and were damaged thereby, excluding defendants and their
families, the officers and directors of First Solar, at all relevant times,
members of their immediate families and their legal representatives, heirs,
successors or assigns and any entity in which defendants have or had a
controlling interest.

5

Doc. 151-6 at 1.

6

A.

7

A proposed class satisfies the numerosity requirement if class members are so

8

numerous that joinder would be impractical. Fed. R. Civ. P. 23(a)(1). Plaintiffs provide

9

evidence that “over 1,300 institutional investors alone held First Solar stock during the

10

Class Period,” and “over 2.9 billion shares of First Solar stock traded during the Class

11

Period.” Doc. 160 at 13 (citing Doc. 158-3 at 5-6). Clearly there are enough class

12

members to make joinder impracticable.

Numerosity.

13

B.

Commonality.

14

Commonality exists if there are questions of law or fact common to the class.

15

Fed. R. Civ. P. 23(a)(2). “This does not mean merely that they have all suffered a

16

violation of the same provision of the law[.]” Dukes, 131 S. Ct. at 2551. Rather, the

17

common contention underlying the claims “must be of such a nature that it is capable of

18

class-wide resolution – which means that determination of its truth or falsity will resolve

19

an issue which is central to the validity of the claims in one stroke.” Id. Because “the

20

complaint alleges a common course of conduct over the entire period directed against all

21

investors, generally relied upon, and violating common statutory provisions, it

22

sufficiently appears that the questions common to all investors will be relatively

23

substantial.” Blackie v. Barrack, 524 F.2d 891, 902-03 (9th Cir. 1974) (quoting Harris v.

24

Palm Springs Alpine Estates, Inc., 329 F.2d 909, 914 (9th Cir. 1964)).

25

C.

Typicality.

26

A proposed class meets the typicality requirement when “the claims or defenses of

27

the representative parties are typical of the claims and defenses of the class.” Fed. R.

28

Civ. P. 23(a)(3). A plaintiff’s claim “is typical if it arises from the same event or practice

-3-

1

or course of conduct that gives rise to the claims of other class members and his or her

2

claims are based on the same legal theory.” Hunt v. Check Recovery Sys., Inc., 241

3

F.R.D. 505, 511 (N.D. Cal. 2007) (quotation marks and citations omitted). Plaintiffs

4

argue that their claims are typical because they “are based on the same theories of

5

liability, and will be proved by the same evidence” as the class claims. The Court agrees.

6

D.

Adequacy of Representation.

7

Adequacy requirement is satisfied if the representative parties will fairly and

8

adequately protect the interests of the class. Fed. R. Civ. P. 23(a)(4). This requires that

9

plaintiffs have no conflict of interest with the proposed class and be represented by

10

competent counsel. See Hanlon v. Chrysler Corp., 150 F.3d 1011, 1020 (9th Cir. 1998).

11

There is no evidence that Plaintiffs or their counsel have a conflict of interest with other

12

class members, and the Court previously concluded that Lead Plaintiffs “made a prima

13

facie showing of adequacy,” including in their choice of counsel. Doc. 89 at 5. Plaintiffs

14

are adequate representatives of the class.

15

III.

Rule 23(b)(3) Predominance.

16

“The predominance inquiry of Rule 23(b)(3) asks whether proposed classes are

17

sufficiently cohesive to warrant adjudication by representation.” In re Wells Fargo Home

18

Mortg. Overtime Pay Litig., 571 F.3d 953, 957 (9th Cir. 2009) (internal quotation marks

19

and citation omitted). “Considering whether questions of law or fact common to class

20

members predominate begins, of course, with the elements of the underlying cause of

21

action.” Erica P. John Fund, Inc. v. Halliburton Co., 131 S. Ct. 2179, 2184 (2011)

22

(internal quotation marks omitted). “The elements of a private securities fraud claim

23

based on violations of § 10(b) and Rule 10b-5 are: ‘(1) a material misrepresentation or

24

omission by the defendant; (2) scienter; (3) a connection between the misrepresentation

25

or omission and the purchase or sale of a security; (4) reliance upon the misrepresentation

26

or omission; (5) economic loss; and (6) loss causation.’”1

Id. (quoting Matrixx

27
1

28

Section 20(a) of the 1934 Act allows for liability of control persons when
someone within their control violates another section of the 1934 Act. Because this claim
requires proof of a § 10 and Rule 10b-5 violation, the predominance inquiry is the same.
-4-

1

Initiatives, Inc. v. Siracusano, 131 S. Ct. 1309, 1317 (2011)).

“Whether common

2

questions of law or fact predominate in a securities fraud action often turns on the

3

element of reliance.” Id. “To obtain class certification in a 10b-5 securities fraud case,

4

the plaintiff . . . must convince the district court that the element of reliance is common to

5

the class.” Amgen I, 660 F.3d at 1172.

6

“Predominance is a test readily met in certain cases alleging . . . securities fraud,”

7

Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 625 (1997), because plaintiffs usually do

8

not need to prove individual reliance and can instead “invoke a rebuttable presumption of

9

reliance based on what is known as the ‘[fraud on the market]’ theory,” Halliburton, 131

10

S. Ct. at 2185; see also Basic, Inc. v. Levinson, 485 U.S. 224, 241-49 (1988) (endorsing

11

fraud on the market theory). That theory relies on “the principle that the market price of

12

a security traded in an efficient market reflects all public information and therefore that a

13

buyer of the security is presumed to have relied on the truthfulness of the information in

14

purchasing the security.” Amgen I, 660 F.3d at 1172; see also Basic, 485 U.S. at 241-42.

15

It “facilitates class certification by recognizing a rebuttable presumption of classwide

16

reliance on public, material misrepresentations when shares are traded in an efficient

17

market.” Amgen II, 133 S. Ct. at 1193. “Absent the [fraud on the market] theory, the

18

requirement that Rule 10b-5 plaintiffs establish reliance would ordinarily preclude

19

certification of a class action [under Rule 23(b)(3)] because individual reliance issues

20

would overwhelm questions common to the class.” Amgen II, 133 S. Ct. at 1193 (citing

21

Basic, 485 U.S. at 242).

22

A.

Plaintiffs’ Exclusive Reliance on Fraud on the Market.

23

Plaintiffs argue that the predominance requirement is satisfied by the simple fact

24

that they will never seek to prove individual class member reliance on false statements of

25

Defendants. Instead, they will show reliance through the fraud on the market theory.

26

Because fraud on the market (and therefore reliance) will either be proved or fail for the

27

class as a whole, common issues necessarily will predominate. As a result, Plaintiffs

28

assert, the Court need not make any inquiry into the efficiency of the market for First

-5-

1

Solar stock at the class certification stage – the Court can conclude with confidence that

2

common issues will predominate simply because Plaintiffs rely exclusively on the fraud

3

on the market theory of reliance. This argument has some logical force, but the Court

4

cannot accept it.

5

First, the argument is contrary to established Rule 23 case law. Every securities

6

fraud class action based on the fraud on the market theory disclaims any intent to prove

7

reliance on the part of individual class members. Such cases are premised on the fact that

8

the class representatives will prove reliance solely through fraud on the market. Courts

9

nonetheless require class plaintiffs to prove market efficiency at the class certification

10

stage.

See Dukes, 131 S. Ct. at 2552 n.6 (“To invoke [the fraud on the market]

11

presumption, the plaintiffs seeking 23(b)(3) certification must prove that their shares

12

were traded on an efficient market, an issue they will surely have to prove again at trial in

13

order to make out their case on the merits.” (emphasis in original; citation omitted));

14

Halliburton, 131 S. Ct. at 2185 (at class certification stage, “plaintiffs must demonstrate

15

. . . that the stock traded in an efficient market”); Amgen I, 660 F.3d at 1175 (“the district

16

court was correct to require [plaintiff] to prove at the class certification stage that the

17

market for [defendants’] stock was efficient”); In re Diamond Foods, Inc., Sec. Litig., No.

18

C 11-05386 WHA, 2013 WL 1891382, at *10 (N.D. Cal. May 6, 2013) (“a showing of

19

market efficiency is clearly required at the class certification stage in an action relying on

20

the [fraud on the market] theory”).

21

Second, Rule 23 requires more than careful pleading. Under Plaintiffs’ theory, the

22

predominance question as to reliance would begin and end at the class complaint. If the

23

complaint relied exclusively on the fraud on the market theory, no further factual inquiry

24

would be needed. The Supreme Court has made clear, however, that “Rule 23 does not

25

set forth a mere pleading standard.” Dukes, 131 S. Ct. at 2551 (citation omitted). “A

26

party seeking class certification must affirmatively demonstrate his compliance with

27

[Rule 23.]” Id. Thus, courts at the class certification stage engage in “rigorous analysis”

28

that entails “some overlap with the merits of the plaintiff’s underlying claim.” Id.

-6-

1

Plaintiffs’ pleadings-only approach would conflict with these clear Supreme Court

2

instructions.

3

Third, Plaintiffs cite no case where common issues were found to predominate on

4

the issue of reliance solely because the plaintiffs relied exclusively on a fraud on the

5

market theory. Plaintiffs ask this Court to break new ground. The Court declines the

6

invitation.

7

Plaintiffs cite Halliburton, Amgen I, and Amgen II in support of their argument.

8

Halliburton held that plaintiffs need not establish loss causation in order to invoke the

9

fraud on the market theory of reliance at the certification stage. 131 S. Ct. at 2183-85. In

10

Amgen I, the Ninth Circuit held that plaintiffs need not prove materiality to invoke the

11

fraud on the market theory, 660 F.3d at 1175-76, and the Supreme Court affirmed in

12

Amgen II, 133 S. Ct. 1184.

13

Rule 23(b)(3) by pleading exclusive reliance on the fraud on the market theory.

These cases do not hold that plaintiffs can satisfy

14

In sum, the Court is not persuaded by Plaintiffs’ novel argument. Plaintiffs must

15

prove at this stage of the litigation that questions of law or fact common to the class

16

predominate over questions affecting only individual members.2

17

B.

Plaintiffs Rule 23(b)(3) Proof.

18

Because reliance is an issue on which individual issues can predominate in a

19

securities fraud case, and the fraud on the market theory is designed to prove reliance on

20

a class-wide basis, Plaintiffs must prove at the class certification stage that they can

21

utilize the fraud on the market theory. To do so, plaintiffs must show that the alleged

22

misrepresentations were publicly known, that the stock transactions occurred between the

23

time the misrepresentations were made and the time the truth was revealed, and that the

24

stock traded on an efficient market. Halliburton Co., 131 S. Ct. at 2185. Defendants’

25

sole argument in opposing class certification is that Plaintiffs have failed to show that

26

First Solar stock traded on an efficient market. To prove market efficiency, Plaintiffs

27
2

28

To the extent Plaintiffs disclaim any intent to prove individual reliance, this fact
must be made clear in the class notice. Class members must understand that they will be
giving up any individual reliance claims if they choose not to opt out of the class.
-7-

1

submit that the NASDAQ is entitled to a presumption of efficiency, and that the five

2

factors identified in Cammer v. Bloom, 711 F. Supp. 1264, 1285-87 (D.N.J. 1989), also

3

show market efficiency.

4

1.

Presumption of Market Efficiency.

5

NASDAQ is “one of the two largest stock exchanges in the United States, the

6

largest electronic-equity securities trading market in the United States, and one of the

7

largest stock exchanges in the world.” Lumen v. Anderson, 280 F.R.D. 451, 459 (W.D.

8

Mo. 2012). Because generally “the market price of shares traded on well-developed

9

markets reflect[] all publicly available information,” Basic, 485 U.S. at 246, some courts

10

have found that trading on a major exchange weighs in favor of finding that the stock

11

traded in an efficient market. See, e.g., In re DVI, Inc. Sec. Litig., 639 F.3d 623, 634, (3d

12

Cir. 2011) (“the listing of a security on a major exchange such as the NYSE or NASDAQ

13

weighs in favor of a finding of market efficiency”), abrogated on other grounds by

14

Amgen II, 133 S. Ct. 1184; Lumen, 280 F.R.D. at 459 (“It would be remarkable for a

15

court to conclude NASDAQ is not an efficient market – which is why securities traded on

16

NASDAQ are often presumed to be traded on an efficient market.” (internal quotation

17

marks, brackets, and citations omitted)); In re Juniper Networks, Inc. Sec. Litig., 264

18

F.R.D. 584, 591 (N.D. Cal. 2009) (“Plaintiffs made a prima facie showing that the [fraud

19

on the market] presumption of reliance applied because . . . stock was actively traded on

20

an efficient market – the NASDAQ.”). The Supreme Court’s decision in Basic appears to

21

support such a presumption. See 485 U.S. at 246 (“In drafting [the 1934] Act, Congress

22

expressly relied on the premise that securities markets are affected by information, and

23

enacted legislation to facilitate an investor’s reliance on the integrity of those

24

markets. . . . Recent empirical studies have tended to confirm Congress’ premise that the

25

market price of shares traded on well-developed markets reflects all publicly available

26

information, and, hence, any material misrepresentations.” (citations omitted)).

27

Defendants argue that there is no presumption of market efficiency for securities

28

listed on a major national exchange. In support, Defendants cite George v. China Auto.

-8-

1

Sys., Inc., No. 11 Civ. 7533 (KBF), 2013 WL 3357170 (S.D.N.Y. July 3, 2013); Dean v.

2

China Agritech, No. CV 11-01331-RGK (PJWx), 2012 WL 1835708, at *6-8 (C.D. Cal.

3

May 3, 2012); In re PolyMedica Corp. Sec. Litig., 453 F. Supp. 2d 260, 278-79 (D. Mass.

4

2006) (PolyMedica II); In re Northfield Labs., Inc. Sec. Litig., 267 F.R.D. 536

5

(N.D. Ill. 2010); and Bell v. Ascendant Solutions, Inc., 422 F.3d 307, 316 (5th Cir. 2005).

6

Of these cases, however, only PolyMedica II considered the significance of a stock’s

7

listing on a national exchange, and even there the district court noted “that listing on such

8

an exchange undisputably improves the market structure for trading in a particular stock”

9

and “that one would be hard-pressed to deny the relevance of this fact in an efficiency

10

analysis.” 453 F. Supp. 2d at 266 (citing O’Neil v. Appel, 165 F.R.D. 479, 504 (W.D.

11

Mich. 1996)). Bell noted only that the district court “was well within its reason to find

12

this fact alone insufficient to show market efficiency,” 422 F.3d at 315, and the other

13

cited cases appear to have ignored the fact that the securities were listed on large national

14

exchanges, see, e.g., China Auto. Sys., 2013 WL 3357170; China Agritech, 2012 WL

15

1835708; Northfield Labs., 267 F.R.D. 536.

16

At oral argument, Defendants represented that Binder v. Gillespie, 184 F.3d 1059

17

(9th Cir. 1999), rejected any presumption of market efficiency based on the size of the

18

exchange. In Binder, the stock initially traded exclusively on the over-the-counter market

19

and then later on the Boston Stock Exchange (“BSE”). Id. at 1064-65. The district court

20

determined that plaintiff could not invoke the fraud on the market presumption with

21

respect to the period in which the stock traded exclusively on the over-the-counter

22

market, and thus decertified the class for this period. Id. For the period in which the

23

stock traded on the BSE, the district court noted that there was no showing that the BSE

24

was an inefficient market, but it “nonetheless decertified the class for the remaining

25

period . . . on the ground that [plaintiff] could not prove causation.” Id. at 1065. The

26

Ninth Circuit affirmed the district court, but did not discuss the appropriateness of

27

employing a presumption of market efficiency to established markets. Binder therefore

28

does not support Defendants’ position.

-9-

1

In keeping with Basic and the other cases cited in the first paragraph of this

2

section, the Court concludes that the trading of First Solar stock on NASDAQ – a major,

3

well-developed stock exchange – weighs in favor of finding market efficiency.

4

Defendants have not “identified any authority, binding or otherwise, that has held that

5

common shares traded on the NASDAQ are not traded in an efficient market.” Diamond

6

Foods, 2013 WL 1891382 at *10. Moreover, Defendants’ expert, Dr. Gompers, agrees

7

that “[m]ost of the time, . . . stocks traded on large national exchanges are likely to be

8

efficient.” Doc. 165-1 at 15.

9

2.

The Five Cammer Factors.

10

The district court’s decision in Cammer outlined a five-factor test for market

11

efficiency that has been widely utilized. The factors are “first, whether the stock trades at

12

a high weekly volume; second, whether securities analysts follow and report on the stock;

13

third, whether the stock has market makers and arbitrageurs; fourth, whether the company

14

is eligible to file SEC registration form S-3, as opposed to form S-1 or S-2; and fifth,

15

whether there are ‘empirical facts showing a cause and effect relationship between

16

unexpected corporate events or financial releases and an immediate response in the stock

17

price.’” Binder, 184 F.3d at 1065 (quoting Cammer, 711 F. Supp. at 1286-87); see also

18

Miller v. Thane Int’l, Inc., 615 F.3d 1095, 1103 (9th Cir. 2010) (noting that the Cammer

19

test “was developed in support of a judicial presumption allowing plaintiffs to avoid a

20

significant obstacle in certifying a class in securities fraud litigation.”). It has been

21

suggested that “[t]he first four Cammer factors indirectly assess market efficiency by

22

evaluating whether the attributes of the market for that security are conducive to

23

informational efficiency.” In re Countrywide Fin. Corp. Sec. Litig., 273 F.R.D. 586, 613

24

(C.D. Cal. 2009) (citing PolyMedica I, 432 F.3d at 18; In re Xcelera.com Sec. Litig., 430

25

F.3d 503, 511 (1st Cir. 2005)). Defendants submit that the fifth factor is the most

26

important because it alone “explores whether an important result of an efficient market

27

exists,” as opposed to simply “relying on circumstantial evidence that a security’s market

28

- 10 -

1

is conducive to efficiency[.]” Countrywide, 273 F.R.D. at 614 (emphasis in original).3
a.

2

Four of the Cammer Factors.

3

Plaintiffs provide evidence that the first, second and fourth Cammer factors, and at

4

least part of the third, are satisfied: First Solar stock traded at a high weekly volume, a

5

significant number of securities analysts followed and reported on the stock, there were at

6

least 31 market makers for the stock as well as some 1,200 institutional investors who

7

traded on public information, and First Solar was eligible to file an S-3 registration

8

statement throughout the Class Period and did so on April 2, 2009. Doc. 160 at 18-19

9

(citing Doc. 158-3 at 6-23). In addressing the fifth factor – whether a cause and effect

10

relationship existed between unexpected corporate events and a quick response in First

11

Solar’s stock price – Plaintiffs point to five days within the Class Period where the price

12

of First Solar stock responded to a company-specific news event (Doc. 160 at 20 (citing

13

Doc. 158-3 at 24-26)), evidence that statistically significant price movements occurred

14

Defendants do not dispute Plaintiffs’ evidence on the first, second, or fourth

4

711 F. Supp. at 1286-87); see also Countrywide, 273 F.R.D. at 612 (“the presence of

5

‘arbitrageurs’ – those who quickly exploit (usually small) price differences among

6

different markets – help bring prices across markets quickly into line with one another,

7

enabling different markets to reflect the same information.”). As noted, Plaintiffs show

8

that there were 31 market makers for First Solar stock during the Class Period as well as

9

more than 1,200 investors. Defendants contend that Plaintiffs ignore arbitrageurs.

10

Defendants assert that arbitrageurs were unable to participate in the market

11

effectively during the Class Period. Relying on the opinion of Dr. Gompers, Defendants

12

submit that because short-selling was expensive and difficult during part of the Class

13

Period (id. at 18 (citing Doc. 162-2, ¶¶ 54, 57, 59)), “the market for short-selling the

14

stock became constrained, and the stock price could not fully and rapidly reflect all

15

negative information during that portion of the class period” (id. at 19 (citing Doc. 162-2,

16

¶ 54)).4 Defendants suggest that “[i]n efficient markets, arbitrageurs can easily ‘short’

17

stocks.” Doc. 161 at 13. But “[w]hen short-selling is expensive or difficult, the arbitrage

18

market becomes ‘constrained’ in that short-sellers cannot act on their views of the stock’s

19

value” and “the market may not fully and rapidly incorporate new negative information

20

into the stock price.” Id. (citing Doc. 162-2, ¶¶ 44-45).

21

Defendants submit that the arbitrage market for First Solar stock became

22

constrained in response to an “extraordinarily high” interest in short selling that in turn

23

caused the cost of borrowing First Solar stock for short-selling purposes to “skyrocket.”

“In a short-sale transaction, the seller borrows shares that the seller believes to be
overvalued from a broker, and pays the broker a so-called ‘loan fee’ for the right to
borrow the shares plus collateral (in cash) for the value of the shares (which is held in an
interest-bearing margin account). The seller agrees to return shares of a similar type and
amount to the broker at an unspecified date in the future. The seller then sells the
borrowed stock.” In re PolyMedica Corp. Sec. Litig., 432 F.3d 1, 9 n.13 (1st Cir. 2005)
(PolyMedica I). If the stock price drops as the seller expects, the seller can purchase it
for a lower price and return it to the broker as promised, having profited from the
difference between the higher sale price and lower purchase price.

Doc. 161 at 18.

Dr. Gompers identified an eleven-week period, from June 6 to

2

August 25, 2011, during which there was both significant interest in short-selling and an

3

increase in borrowing fees. Id. (citing Doc. 162-2, ¶¶ 54, 57, 59). Dr. Gompers also

4

found that the amount of time it took “to cover (i.e., repurchase) all shares sold short”

5

increased from one day at the beginning of the Class Period to 18.9 days as of July 29,

6

2011. Doc. 162-2, ¶ 54. Due to significant short-selling interest, high loan fees, and the

7

additional days required to cover short positions, Dr. Gompers opines that “arbitrage in

8

First Solar stock was constrained over sizeable stretches of the putative class period.”

9

Id., ¶ 60.

10

To show the relevancy of this short-sale analysis, Defendants rely primarily on

11

PolyMedica II, 453 F. Supp. 2d at 273, a case in which the court noted that impediments

12

to short selling constitute “indirect evidence” of market inefficiency. Doc. 161 at 13, 19.

13

The defendant in PolyMedica II offered evidence that short-selling was difficult during

14

the contested period because (1) the interest in short-selling began to “skyrocket,”

15

(2) “finding shares to short became very difficult,” and (3) “the transaction costs for short

16

selling . . . became extraordinarily high.” Id. at 273-74. The court also noted, however,

17

that “[t]he tangible effect of these constraints on short selling is seen in yet another piece

18

of evidence proffered by [defendant]: violations of put-call parity.” Id. at 274. This

19

evidence was significant because “[u]sing derivative securities called ‘puts’ and ‘calls’

20

(together, ‘options’) in combination with short sales, arbitrageurs can make guaranteed

21

profits if certain conditions are present,” that is, if put-call parity is violated. Id. at 274-

22

75.5 According to PolyMedica II, arbitrageurs correct put-call disparities by engaging in

23

short-sales, and because short-selling constraints restrict an arbitrageur’s ability to exploit

24

put-call disparities, the constraints may be evidence of market inefficiency. Id.; see also

25

id. at 275 (“In an information efficient market, disparities do correct, and there are no

“A ‘put’ is the right to sell a security at a certain price (the ‘strike price’) by a

‘call’ is the right to buy a security at a certain price by a certain date.” Id., at 274 n.15.
Put-call parity is where “Price of Call Option + Strike Price on Option = Price of Put
Option + Current Price of Stock.” Id. at 274-75.

2

n.78 (“an arbitrage opportunity cannot be exploited if there are other impediments to

3

transactions. These impediments suggest inefficiency and may include, for example, the

4

situation where costs to make the transaction . . . are higher than the theoretical profit

5

opportunity.” (citing PolyMedica II, 453 F. Supp. 2d at 273-74)).

6

The Court has three concerns about Defendants’ short-sale argument. First, it is

7

unclear from PolyMedica II whether impediments to short selling demonstrate market

8

inefficiency absent a corresponding put-call disparity, and Defendants present no

9

evidence of such disparity in this case. Second, while arguing that there were serious

10

impediments to short selling First Solar stock, Defendants also note admit that “of all the

11

stocks traded on the NASDAQ, First Solar was one of the most heavily ‘shorted’ stocks

12

during the proposed class period.” Doc. 161 at 12 (citing Doc. 162-2, ¶¶ 53-60). Third,

13

Defendants’ evidence suggests that short selling was constrained for only 11 weeks out of

14

the four-year Class Period.

15

Despite these misgivings, Defendants’ short-sale evidence warrants consideration

16

in the class certification analysis.

It is “helpful to a plaintiff seeking to allege an efficient market to allege empirical

facts showing a cause and effect relationship between unexpected corporate events or

At oral argument, Defendants stated that Dr. Gompers opined in his declaration
that short sale impediments constitute “direct evidence” of market inefficiency. Dr.
Gompers points to “direct evidence” of short selling impediments (Doc. 162-2, ¶¶ 54-57,
59-60), and to academic articles about short selling in general (id., ¶¶ 44, 46-47, 50-52),
but he does not appear to opine that short sale impediments are direct evidence of market
inefficiency. See id., ¶ 18 (“constraints to arbitrage as represented by a limited ability to
short a particular security are indicative of a market that may not be able to efficiently
incorporate new value-relevant public information.” (emphasis added)).

the market theory.” Id.

2

Plaintiffs point to five days within the Class Period in which a statistically

3

significant price reaction at the 1% level7 followed a First Solar-specific news event:

4

(1) First Solar filed a Form 8-K and hosted an earnings conference call on July 29, 2010,

5

and the next day the price of First Solar stock declined 7.42%; (2) First Solar filed a Form

6

8-K and hosted an earnings call on February 24, 2011, and the next day the stock price

7

declined 5.44%, and another 5.35% after trading; (3) First Solar issued a press release

8

announcing its Chief Executive Officer’s (“CEO”) departure and the appointment of an

9

interim CEO on October 25, 2011, and the next day the price of First Solar stock declined

10

25.33%; (4) First Solar filed a Form 8-K and hosted a guidance conference call on

11

December 14, 2011, and later that day the price of First Solar stock declined 25%. Doc.

12

160 at 20 (citing Doc. 158-3 at 24-26). Over the entire Class Period of 966 trading days,

13

Plaintiffs assert that there were statistically significant price moves on 49 days (id. at 20

14

n.9), with statistically significant price moves occurring on 13 of the 16 days when First

15

Solar earnings releases occurred, and 13 of the last 14 of those days (id.). Plaintiffs

16

submit that, overall, statistically significant price moves occurred three times more often

17

on days with relevant news than on days without news. Id. (citing Doc. 158, ¶¶ 3-4).

18

Five Event Days.

19

According to Defendants, Dr. Steinholt’s study of only five event days is

20

insufficient proof of market efficiency because those five days represent a small portion

21

of the Class Period. Id. at 14-15. They point to China Automotive Sys., 2013 WL

22

3357170 at *12, which found that a “showing that only seven out of sixteen days resulted

23

in a market reaction is an insufficient foundation upon which to pronounce market

24

efficiency.” It does not appear, however, that the China Automotive finding was based on

“A statistically significant price movement is one that is unlikely to have
occurred simply by chance. A price movement is statistically significant at the 1% level
if the magnitude of the price movement has a 1% or less chance of occurring randomly.”
Doc. 158-2 at 16 n.19. Plaintiffs’ expert, Dr. Steinholt, computed statistical significance
by reviewing “the public mix of information (SEC filings, press releases, conference
calls, analyst reports and Bloomberg media), as well as an analysis of statistical
significance for each day[.]” Id., ¶ 28; see also id. at 233.

the 22-month class period, as Defendants suggest (Doc. 161 at 14), but instead on the less

2

than 50% showing of statistically significant stock price reactions in the right direction on

3

predefined dates expected to impact stock pricing. Id. at *11-12. Defendants also point

4

to a footnote in Countrywide, 273 F.R.D. at 618 n.96, describing the problems of

5

subjective determinations in event studies and noting that ambiguity in such studies “can

6

be reduced by increasing the sample size (number of ‘observations’), ensuring the sample

7

is representative (e.g., by studying a random sample of days with both large and small

8

returns), and objectively defining ‘new’ information.” Additionally, Defendants note that

9

the five event days are not evenly distributed throughout the Class Period. Doc. 161 at

10

14. Defendants point to PolyMedica II’s conclusion that plaintiff’s expert’s selection of

11

“the largest stock price drops” – five days out of about 160 trading days – “proves

12

nothing.” 453 F. Supp. 2d at 169-70. But Dr. Steinholt appears to have done better than

13

the expert in PolyMedica II because his event study considered statistically significant

14

price movements (Doc. 158-2, ¶¶ 28-33), whereas the PolyMedica II expert examined

15

general price fluctuations only, 453 F. Supp. 2d at 169-70.

16

Defendants criticize Dr. Steinholt’s event selection “because he did not use

17

articulable objective criteria to select news events[.]”

Doc. 161 at 17-18 (citing

18

Countrywide, 273 F.R.D. at 618 (“the events for study should be selected using criteria

19

that are as objective as possible.”). Defendants presume that Dr. Steinholt selected some

20

of the events, and the CEO resignation announcement in particular, “only because it

21

coincided with a statistically significant stock reaction” (id. at 18).

22

acknowledged that “unless the expert uses articulable objective criteria [to select events],

23

it is difficult to evaluate the probative value of expert evidence without evaluating also

24

the expert’s own credibility.” Countrywide, 273 F.R.D. at 618. Additionally, Defendants

25

argue that Dr. Steinholt’s event selection is insufficient because he did not consider any

26

of the alleged misstatements at issue in this case. Doc. 161 at 15.

Courts have

27

These criticisms have some merit. They suggest that Dr. Steinholt’s event days

28

were not selected with fully objective criteria, and that five days during a four-year class

- 16 -

1

period certainly is not comprehensive. But Defendants do not dispute that statistically

2

significant price reactions at the 1% confidence level followed five significant

3

announcements regarding First Solar’s financial condition. Thus, although Defendants

4

have provided reason to believe that Plaintiffs’ event days are not fully objective and are

5

somewhat incomplete, they have not shown the data to be inaccurate.

6

As to Plaintiffs’ comparison of “news” versus “non-news” days, Defendants argue

7

that Plaintiffs’ counsel, who is not an expert in market efficiency, made the comparison

8

and Plaintiffs cannot supplement their expert report after the close of discovery.

9

Doc. 161 at 16. The Court disagrees with both arguments. Instead of offering an expert

10

opinion, Plaintiffs’ counsel performed calculations on the data in Dr. Steinholt’s report.

11

See Doc. 164 at 12-13 n.7. The Court could have performed the same calculations given

12

the data in the report, and does not consider such calculations to constitute new expert

13

opinions.
ii.

14

81.25%.

15

With respect to Plaintiffs’ assertion that First Solar stock made significant price

16

moves in response to 81.25% of the earnings reports released during the Class Period,

17

Defendants argue that Plaintiffs must show that the stock traded efficiently throughout

18

the Class Period. Doc. 161 at 16. Although the Court generally agrees, evidence of

19

market efficiency on some days can be indicative of market efficiency on other days, and

20

many days are simply flat as to price and news, leaving little with which to prove market

21

efficiency. The Court does not agree with Defendants’ suggestion that the fifth Cammer

22

factor requires a day-by-day showing of market efficiency for class certification.

23

Cammer states that “it would be helpful” for a plaintiff to “allege empirical facts” as to

24

the fifth factor, but Cammer does not require empirical facts as to every trading day. 711

25

F. Supp. at 1287.

26

Additionally, Defendants contend that Lumen does not support Plaintiffs’ assertion

27

that 81.25% “is good enough” because Plaintiffs have not shown statistically significant

28

movement on every “news” day as was shown in Lumen. In considering the fifth

- 17 -

1

Cammer factor, Lumen noted that the defendants submitted evidence that on 35% of the

2

days in which the stock exhibited statistically significant stock movement, there was no

3

company-specific news. 480 F.R.D. at 461. Lumen found that this also “means that 65%

4

of the time statistically significant stock price moves are related to company-specific

5

news.” Id. Lumen did not find that there was statistically significant movement on every

6

“news” day. The Court also notes that in DVI, 639 F.3d at 635, the Third Circuit

7

concluded that the district court did not err in finding that 60% and 65% correlations

8

between news releases and stock price changes weighed in favor of market efficiency.

9

Accordingly, the Court cannot accept Defendants’ assertion that because 81.25% is not

10

100%, Plaintiffs have made an insufficient showing with respect to Cammer factor five.8
iii.

11

Defendants’ Cammer Factor Five Evidence.

12

Defendants point to two instances in which the price of First Solar stock did not

13

have a statistically significant response to unexpected good news: (1) First Solar issued

14

an unexpectedly positive quarterly earnings release on April 30, 2008, and the residual

15

return following the release was .76%, and (2) First Solar issued an unexpectedly positive

16

quarterly earnings release on July 30, 2008, and the residual return following the release

17

was 1.06%. Doc. 161 at 15 (citing Doc. 162-2, ¶¶ 28, 40). Dr. Gompers found that the

18

stock price reactions to these two earnings announcements did not result in statistically

19

significant reactions (Doc. 162-2, ¶ 40), and that the reactions “were at odds with what

20

you would expect from a full and rapid incorporation of new-value relevant information”

21

(Doc. 162-5 at 18:16-18). This evidence, although worthy of consideration, is less than

22
8

23
24
25
26
27
28

At oral argument, Defendants suggested that Plaintiffs’ assertion that the stock
price reactions to 13 out of the 16 earnings reports was not evidence of market efficiency
because, unlike a properly conducted event study, Plaintiffs did not attempt to control for
the effect of market and industry factors with respect to these particular stock price
reactions. But Plaintiffs cite to Dr. Steinholt’s analysis of the statistical significance of
each stock price movement to a particular First Solar news event (Doc. 158, ¶ 5 (citing
Doc. 158-2 at 59-233)), and that analysis appears to have calculated the statistical
significance of the stock price reaction for all 16 earnings reports. Moreover,
Dr. Gompers notes that his “statistical approach is different from Steinholt’s in only one
respect – Steinholt does not exclude days of alleged misrepresentations and corrective
disclosures from his estimation windows.” Doc. 162-2, ¶ 26. It is unclear how this
difference between the methodologies of the parties’ experts affects the showing made as
to the First Solar stock price reaction to the 13 earnings reports.

conclusive. See Lumen, 280 F.R.D. at 461 (noting that Dr. Gompers’ opinion that the

2

“stock did not incorporate public information . . . [is] wanting” because it “is based on

3

only two days on which [the stock] experienced no significant change in stock price

4

despite the announcement of important news. From this, he concludes the market was

5

inefficient.

6

significant price changes following important news.”).9

However, there is no comparison to the number of times there were

7

Defendants argue that Dr. Steinholt’s “event study shows two back-to-back days

8

of statistically significant stock reactions on December 16 and 17, 2008” when “there was

9

no value relevant news on either day.” Doc. 161 at 20. Defendants submit that “[w]hen

10

the market for a stock is operating efficiently, that should not happen” (id.), and that “the

11

likelihood of it happening by pure chance is less than one one-hundredth of one percent

12

(0.01%)” (id.).

13

Defendants also argue that evidence of serial correlation demonstrates market

14

inefficiency. Defendants submit that “[i]n an efficient market, an investor cannot predict

15

future stock prices based on past movements.” Doc. 161 at 20 (citing PolyMedica II, 453

16

F. Supp. 2d at 276-77; Countrywide, 273 F.R.D. at 614). Defendants then point to their

17

expert’s finding of serial correlation in First Solar stock prices from June 6 to August 25,

18

2011. Id. (citing Doc. 162-2, ¶ 63). Serial correlation may be evidence of market

19

inefficiency because if past stock price returns tend to predict current or future returns,

20

there is a delay in the adjustment of stock prices to new information and thus “the

21

direction in which price moves today is a statistically significant predictor of the direction

22

in which it will move tomorrow[.]” PolyMedica II, 453 F. Supp. 2d at 277. Although in

23

PolyMedica II the court found that evidence of serial correlation, in combination with

24
9

25
26
27
28

Defendants also submit that Dr. Gompers “identified five additional earnings
announcement days that appeared to be inconsistent with market efficiency.” Doc. 161 at
15 n.15 (citing Doc. 162-5 at 2:5-14); see also Doc. 162-5 at 27:10-12 (describing that on
each of these days there was “an inconsistent reaction to the particular type of news that’s
being released on those days”). But Dr. Gompers did not rely on these days because they
“weren’t as clear-cut as the examples [he] gave in [his] report” (Doc. 162-5 at 2:11-14),
and the Court therefore will not rely on them either.

of [the serial correlation test], or the appropriateness of the court’s consideration of this

4

evidence during the class-certification proceedings,” 432 F.3d at 18 n.21. Defendants

5

have made a showing of serial correlation for only 11 weeks out of an almost four-year

6

Class Period, and some courts have found that “the presence of serial correlation is not

7

itself determinative of inefficiency.” Countrywide, 273 F.R.D. at 615.
iv.

8

Factor Five Conclusion.

9

Plaintiffs have presented evidence of efficient-market responses on five specific

10

days and evidence of meaningful stock price responses on 81.25% of the days when

11

earnings releases occurred.

12

incomplete, but their own empirical evidence is limited to two days when First Solar

13

stock failed to respond significantly to unexpected good news, two days when it moved

14

significantly in response to no news, and 11 weeks of serial correlation, a factor

15

discounted by at least one court. The Court views this evidence as essentially a stand-off

16

on the fifth Cammer factor. If forced to declare a victor, the Court likely would choose

17

Plaintiffs because of the 81.25% correlation between First Solar earnings reports and

18

significant price moves, but the empirical battle is too close to call on the basis of such

19

limited evidence. The Court has no difficulty, however, reaching a conclusion on the

20

broader question of market efficiency.

Defendants criticize this evidence as nonobjective and

21

D.

Market Efficiency Conclusion.

22

Plaintiffs have shown by a preponderance of the evidence that First Solar stock

23

traded on an efficient market. That evidence includes the following undisputed facts:

24

First Solar stock traded on the NASDAQ, a major and well-developed securities market;

25

the stock traded at high weekly volumes; securities analysts followed and reported on the

26

stock; the stock had 31 market makers during the Class Period and more than 1,200

27

institutional investors; and First Solar was eligible to file and did file SEC registration

28

form S-3. In addition, the First Solar stock price made statistically significant moves on

- 20 -

1

five specific days when noteworthy First Solar news was released and on 81.25% of the

2

days when earnings were released. Defendants have presented evidence that arbitrageurs

3

were likely constrained during a portion of the Class Period, that First Solar stock failed

4

to respond significantly to unexpected good news on two days, that it moved significantly

5

in response to no news on two other days, and that serial correlation is apparent in 11

6

weeks of the Class Period.

7

In weighing this evidence, the Court finds it significant that Plaintiffs have shown

8

without dispute that three of the five Cammer factors are satisfied, that another is

9

partially satisfied, and that the stock traded on the NASDAQ. Defendants’ evidence that

10

the third Cammer factor is partially unsatisfied, and the stand-off on the fifth Cammer

11

factor, simply do not outweigh Plaintiffs’ evidence, even if the fifth factor is considered

12

most important.

efficiency by a preponderance of the evidence, that the fraud on the market theory is

14

warranted in this case, and that common issues will predominate in light of the fraud on

15

The Court therefore concludes that Plaintiffs have shown market

The superiority inquiry asks whether “a class action is superior to other available

18

methods for fairly and efficiently adjudicating the controversy.” Fed. R. Civ. P. 23(b)(3).

that can be adjudicated most profitably on a representative basis[.]” Zinser v. Accufix

22

Research Inst., Inc., 253 F.3d 1180, 1190 (9th Cir. 2001). Plaintiffs submit that “there

23

are no other securities actions pending against defendants; litigating all claims in this

24

District (where First Solar is headquartered) is far more efficient than in the home forum

25

of each class member; and because class-actions are the rule, rather than the exception,

26

for cases under the PSLRA, there will be few, if any, difficulties in managing this case as

27

a class action.” Doc. 160 at 23. Defendants do not contest Plaintiffs’ suggestion that a

28

class action is superior.
