8 Teamsters Local 445 Freight Division Pension Fund (“Teamsters”), lead plaintiffs in a

9 putative securities class action, appeal from an interlocutory order of the United States District

10 Court for the Southern District of New York (Scheindlin, J.). The district court concluded that

11 Teamsters failed to satisfy the predominance requirement of Rule 23(b)(3), Fed. R. Civ. P, and

12 denied its motion for class certification. We agreed to hear this interlocutory appeal to consider

13 whether the district court applied the correct standard of proof—the preponderance of the

14 evidence standard—to this decision. This appeal also raises several ancillary issues: whether the

15 district court made clearly erroneous factual findings in denying class certification; whether it

16 was required to permit a full evidentiary hearing before employing a preponderance of the

17 evidence standard; and whether it was obligated to allow additional class discovery before

18 denying class certification. Finding no error in any of these areas, we affirm.

1 subsidiary of BCI, packaged mobile home loans and sold them to the public as “the Certificates,”

2 the securities that are the subject of this litigation. $1.85 billion worth of Certificates were sold

3 in seven separate offerings between 1998 and 2001, each secured by a distinct pool of mobile

4 home loan contracts and mortgages. The Certificates were typically traded relatively infrequently

5 and in large amounts by sophisticated institutional investors, such as Teamsters. In May 2002,

6 Teamsters purchased $250,000 par value Series 2000-A Class A-2 Certificates for a total

7 investment of $234,826. 

8 In September 2001, BI, BCI, and BCM discontinued debt offerings secured by mobile

9 home loans. In December 2002, the Series 2000A Certificates were downgraded to below

10 investment grade. That same month, the Toronto Star and other papers reported that the price of

11 BI shares had drastically fallen in 2002 in part due to “questions about [its] financing arm,

12 [BCI]” and the National Post announced that BI “could take a goodwill writeoff of up to $2-

13 billion,” in order to “quickly clear up some of the most pressing challenges facing the company’s

14 lending unit.” In March 2003, the Canadian Press reported that BI and BCI were downgraded

2

15 to “under review, with negative implications” and that BI “warned of the prospect of major

16 writedowns,” and the Hamilton Spectator stated that “[n]on-cash writedowns will likely include

1 [BCI], already written down in 2001.”3

2 In February 2005, Teamsters sued. The Complaint alleges that from 1998 to 2001, senior

3 management at BCM, BCI, and BI disregarded underwriting standards, regularly underwrote

4 loans to borrowers who were not creditworthy, and purchased large quantities of facially

5 defective and deficient mobile home loans. The Complaint alleges that these reckless

6 underwriting practices caused escalating delinquency rates, which were systematically

7 underreported. It contends that Certificate prices collapsed following the downgrades and the

8 December 2002 and March 2003 disclosures. The Complaint further alleges that this conduct

9 violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, 15 U.S.C. § 78a et

10 seq., and Rule 10b-5 thereunder, 17 C.F.R. § 240.10b-5. 

11 In February 2006, Teamsters moved pursuant to Rule 23(b)(3) for certification of a class

12 of all open market purchasers of the Certificates between February 7, 2000 and February 7, 2005. 

13 The appellees opposed principally on the ground that Certificate holders were not a proper Rule

14 23(b)(3) class because Teamsters could not adequately demonstrate that Certificate prices timely

15 incorporated information material to the strength of the underlying collateral.

16 The district court denied the motion. Teamsters Local 445 Freight Div. Pension Fund v.

17 Bombardier, Inc., No. 05 Civ. 1898 (SAS), 2006 WL 2161887 (S.D.N.Y. Aug. 1, 2006). It

18 identified the “decisive” question as whether Teamsters could show that class issues

19 predominated over individual issues so that common proof could be used to establish the reliance
 The Basic Inc. v. Levinson fraud-on-the-market theory involves two rebuttable 4

presumptions that permit a finding of class-wide reliance with respect to a Rule 10b-5 claim:

“that (1) misrepresentations by an issuer affect the price of securities traded in the open market,

and (2) investors rely on the market price of securities as an accurate measure of their intrinsic

value.” Hevesi v. Citigroup Inc., 366 F.3d 70, 77 (2d Cir. 2004).

It is “based on the hypothesis that, in an open and developed securities market, the price

of a company’s stock is determined by the available material information regarding the company

and its business” and that “[m]isleading statements will therefore defraud purchasers of stock

even if the purchasers do not directly rely on the misstatements.” Basic, 485 U.S. at 241-242

(internal quotation marks omitted). The theory is premised on the existence of an

informationally efficient market, in which “market professionals generally consider most publicly

announced material statements about companies, thereby affecting stock prices.” Id. at 246 n.24.

5

1 element of their claim under Section 10(b) and Rule 10b-5. Id. at *4. Teamsters invoked the

2 fraud-on-the-market doctrine as one theory of reliance. Id. at *5; see Basic Inc. v. Levinson, 485

3 U.S. 224, 242-49 (1998). The district court concluded that the fraud-on-the-market presumption 4

4 was only available if the Certificates were found to have traded in an “efficient” market, one that

5 was “open and developed enough so that it quickly incorporate[d] material information into the

6 price of the security.” Id. at *5. According to the district court, if Teamsters could “not avail

7 itself of the presumption that investors relied on defendants’ misrepresentations, the requirement

8 that common issues predominate over individual issues [would] not be satisfied, and class

9 certification [would] be denied.” Id. at *1.

10 Believing that the standard of proof for analyzing Teamsters’ evidence of market

11 efficiency “ha[d] not been precisely defined,” the district court determined that the

12 preponderance of the evidence standard applied. Id. at *3, 9. It understood this Court’s decision

13 in Heerwagen v. Clear Channel Communications, 435 F.3d 219 (2d Cir. 2006), to prescribe a

14 binary standard of proof for Rule 23 issues. Teamsters, 2006 WL 2161887, at *4. The district
6

1 court believed that a plaintiff was required to demonstrate by a “preponderance of the evidence”

2 class certification issues that are “sufficiently independent of the merits to justify weighing the

3 evidence,” but to make only “some showing” of issues that are “effectively identical to the

4 merits.” Id. (internal quotation marks omitted). Finding that “the availability of a presumption

5 [of reliance] is not a merits issue,” the district court applied the preponderance of the evidence

6 standard. Id. at *9.

7 The district court analyzed Teamsters’ evidence of market efficiency according to five of

8 the eight factors set forth in Cammer v. Bloom, 711 F. Supp. 1264 (D.N.J. 1989): (1) the average

9 weekly trading volume of the Certificates, (2) the number of securities analysts following and

10 reporting on them, (3) the extent to which market makers traded in the Certificates, (4) the

11 issuer’s eligibility to file an SEC registration Form S-3, and (5) the demonstration of a cause and

12 effect relationship between unexpected, material disclosures and changes in the Certificates’

13 prices. Teamsters, 2006 WL 2161887, at *6-7, 10-12. It found that two factors—the average

14 weekly trading volume of the Certificates expressed as a percentage of the outstanding shares and

15 the filing of an SEC Form S-3 for each class of the Certificates—supported a finding of market

16 efficiency. Id. at *10-11. However, the district court determined that the other three factors—the

17 existence of securities analysts following and reporting on the Certificates, the showing that

18 market makers traded in them, and the demonstration of a causal relationship between the

19 disclosure of material information about the Certificates and their prices—did not. Id. at *10-12. 

20 Based on this analysis and other information available, the district court concluded that

21 Teamsters failed to demonstrate by a preponderance of the evidence that the Certificates traded in
 After we granted leave to appeal, Teamsters withdrew a motion for reconsideration that 5

it had previously filed before the district court.

 Teamsters intended to renew its class certification motion and sought to subpoena the 6

Trustee of the Certificates at issue, the holders of the Certificates during a five-year period, thirty

or more additional broker-dealers and/or institutional purchasers of the Certificates, and

unidentified analysts. 

7

1 an efficient market and therefore could not rely on the fraud-on-the-market presumption. Id. at

2 *12. Because class members would have to prove reliance individually, the court determined

3 that Teamsters could not satisfy Rule 23(b)(3)’s predominance requirement and class

4 certification was denied. Id.

5 In August 2006, shortly after the district court entered its ruling, and after an eleven6 month period of discovery that included a three-month extension, the district court stayed

7 additional discovery. Teamsters then sought, and we granted, leave to appeal the denial of class

8 certification. See Rule 23(f), Fed. R. Civ. P. In December 2006, Teamsters asked the district 5

9 court to lift the stay and to permit an additional six months of discovery to develop more proof

10 that the Certificates traded in an efficient market. It argued that our decision in Miles v. Merrill 6

11 Lynch & Co., (In re Initial Pub. Offerings Sec. Litig.), 471 F.3d 24 (2d Cir. 2006) (“In re IPO”),

12 which was issued after it had moved for class certification, established for the first time that the

13 preponderance of the evidence standard applied to its Rule 23 evidence.

14 The district court denied the request. Teamsters Local 445 Freight Div. Pension Fund v.

15 Bombardier, Inc., No. 05 Civ. 1898 (SAS), at 8 (S.D.N.Y. Jan. 3, 2007) (order denying discovery

16 request). It observed that the holding of In re IPO “was not wholly unanticipated” and that
8

1 Heerwagen had already placed Teamsters “on notice that a court would likely apply the

2 preponderance of the evidence test to any disputed issues of fact requiring resolution in order to

3 make a determination as to class certification, unless that issue was ‘effectively identical’ to a

4 merits issue.” Id. at 3-4, 6. It noted that Teamsters’ request for additional discovery could have

5 been made earlier and that the additional discovery requested was unlikely to cure the

6 deficiencies in the class certification motion. Id. at 5-7.

7 In accepting Teamsters’ appeal, we agreed to consider three questions: (1) whether the

8 “some showing” or “preponderance of the evidence” standard of proof applies to the Rule 23

9 requirements in securities class actions; (2) whether the district court properly applied the

10 preponderance of the evidence standard to Teamsters’ evidence of predominance; and (3)

11 whether the class should be certified because the district court overlooked evidence

12 demonstrating that the Certificates traded in an efficient market, even under a preponderance of

13 the evidence standard.

14

15 DISCUSSION

16 We review for abuse of discretion the district court’s denial of class certification. In re

17 IPO, 471 F.3d at 31. While we also apply the abuse-of-discretion standard to the ruling that

18 Teamsters did not meet the predominance requirement of Rule 23(b)(3), we review for clear error

19 the factual findings underlying the ruling, including the determination that the Certificates do not

20 trade in an efficient market. Id. at 40-41. We review de novo any issues of law underlying the

21 Rule 23 ruling, including the question of whether the district court applied the correct standard of
 Teamsters contends that we should review the denial of its request for an evidentiary

7

hearing de novo because “this issue is inextricably linked to the District Court’s application of

the higher ‘preponderance of the evidence’ standard” to its evidence of predominance. We

disagree. See In re IPO, 471 F.3d at 41 (explaining that in determining class certification, “a

district judge has ample discretion to circumscribe both the extent of discovery concerning Rule

23 requirements and the extent of a hearing to determine whether such requirements are met”).

 Revisions to Rule 23(b)(3) that went into effect after the district court’s denial of the 8

class certification motion superficially altered the rule’s text without substantively changing the

predominance requirement.

9

1 proof. Id. We also review for abuse of discretion a district court’s decision not to hold an

2 evidentiary hearing and to deny further class discovery. Id.; see also Wills v. Amerada Hess 7

3 Corp., 379 F.3d 32, 41 (2d Cir. 2004); Zappia Middle E. Constr. Co. Ltd. v. Emirate of Abu

4 Dhabi, 215 F.3d 247, 253 (2d Cir. 2000).

5

6 A. Standard of Proof for Rule 23 Requirements

7 In determining whether class certification is appropriate, a district court must first

8 ascertain whether the claims meet the preconditions of Rule 23(a) of numerosity, commonality,

9 typicality, and adequacy. It may then consider granting class certification where it “finds that the

10 questions of law or fact common to class members predominate over any questions affecting only

11 individual members, and that a class action is superior to other available methods for fairly and

12 efficiently adjudicating the controversy.” Fed. R. Civ. P. 23(b)(3). This appeal addresses a 8

13 question that weaves through these various requirements of Rule 23: the standard of proof

14 applicable to evidence proffered to meet them.

15 We addressed this very question shortly after the district court denied Teamsters’ motion. 
10

1 In In re IPO, we “readily acknowledge[d]” that our caselaw up until that point “[had] been less

2 than clear.” In re IPO, 471 F.3d at 32. We set forth the following standards, among others, to

3 govern class certification:

4 (1) a district judge may certify a class only after making determinations that each of the

5 Rule 23 requirements has been met; (2) such determinations can be made only if the

6 judge resolves factual disputes relevant to each Rule 23 requirement and finds that

7 whatever underlying facts are relevant to a particular Rule 23 requirement have been

8 established and is persuaded to rule, based on the relevant facts and the applicable legal

9 standard, that the requirement is met; [and] (3) the obligation to make such

10 determinations is not lessened by overlap between a Rule 23 requirement and a merits

11 issue, even a merits issue that is identical with a Rule 23 requirement.

12

13 Id. at 41. We disavowed any implication in our earlier decisions that the “some showing”

14 standard may apply to Rule 23 issues and required district courts “to assess all of the relevant

15 evidence admitted at the class certification stage” when determining whether to grant a Rule 23

16 motion. Id. at 42.

17 The district court, which did not have the benefit of our decision in In re IPO, understood

18 our decision in Heerwagen, 435 F.3d 219, to set forth two different standards of proof,

19 depending on whether a given Rule 23 issue was “effectively identical to the merits.” Teamsters,

20 2006 WL 2161887, at *4 (internal quotation marks omitted). It found that “[t]he use of a

21 presumption to prove transaction causation is simply a procedural tool that allows a plaintiff to

22 satisfy the predominance requirement of Rule 23(b)(3).” Id. at *9. Because the availability of

23 the fraud-on-the-market presumption did not overlap with the merits, the district court applied

24 the preponderance of the evidence standard to Teamsters’ evidence regarding the efficiency of

25 the Certificates’ market. Id.
11

1 Although we did not use the words “preponderance of the evidence” in In re IPO to

2 describe the standard of proof applicable to Rule 23 issues, we in effect required the application

3 of a cognate standard by directing district courts “to assess all of the relevant evidence admitted

4 at the class certification stage,” to “resolve[] factual disputes relevant to each Rule 23

5 requirement,” and “[to] find[] that whatever underlying facts are relevant to a particular Rule 23

6 requirement have been established,” notwithstanding an issue’s overlap with the merits. Id. at

7 41-42. Today, we dispel any remaining confusion and hold that the preponderance of the

8 evidence standard applies to evidence proffered to establish Rule 23’s requirements. The district

9 court therefore applied the correct standard.

10 Teamsters urges a different result for two principal reasons, neither of which is

11 persuasive. It argues first that In re IPO “expressly repudiate[d]” our earlier endorsement of the

12 preponderance of the evidence standard in Heerwagen, and second that we “adopted a middle

13 ground, under which a District Judge is required to make preliminary findings on the class

14 certification issues, but not to apply the preponderance of the evidence standard.” Although In re

15 IPO explicitly overruled our prior decisions in In re Visa Check/MasterMoney Antitrust Litig.,

16 280 F.3d 124 (2d Cir. 2001), and Caridad v. Metro-North Commuter R.R., 191 F. 3d 283 (2d Cir.

17 1999), it only overruled Heerwagen to the extent that the decision supported an application of the

18 “some showing” standard to factual disputes relating to Rule 23 requirements. In re IPO, 471

19 F.3d at 42. Moreover, In re IPO did not establish any “middle ground” standard of proof. 

20 Teamsters makes much of our statement in In re IPO, where we characterized as dictum the

21 statement in Heerwagen that “[c]omplying with Rule 23(b)(3)’s predominance requirement
We explained that the statement was not necessarily correct because

9

[i]f a standard lower than preponderance were permitted, a judge could rule that

predominance is shown by that lesser standard without going further and ruling that

individual issues have been shown to predominate. The evidence might be in equipose,

or the judge might simply not have considered whether the defendant’s contrary evidence

is persuasive. The situation is somewhat similar to a judge ruling that the plaintiff is not

entitled to summary judgment on undisputed facts without ruling that the defendant is

entitled to summary judgment.

In re IPO, 471 F. 3d at 37 n.8. 

12

1 cannot be shown by less than a preponderance of the evidence.” In re IPO, 471 F.3d at 37

2 (quoting Heerwagen, 435 F.3d at 233). This characterization was accurate. Without resolving

3 the issue of the standard of proof actually applied by the district court, Heerwagen narrowly held

4 that if the district court applied the preponderance of the evidence standard, it did not err because

5 the predominance inquiry was sufficiently independent of the merits of the action. Heerwagen,

6 435 F.3d at 233. The accurate characterization of an endorsement of the preponderance of the

7 evidence standard as dictum does not, however, establish a new, “middle ground” standard of

8 proof. Teamsters similarly overstates the significance of a footnote in In re IPO, where we cast

9 doubt on our comment in Heerwagen that “[i]f plaintiff had a lesser burden, then a motion to

10 certify a Rule 23(b)(3) class would be granted despite the motion judge’s belief that it is more

11 likely than not that individual issues would predominate.” In re IPO, 471 F. 3d at 37 n.8 (citing

12 Heerwagen, 435 F.3d at 233). Our footnote merely limited what was essentially dictum in

13 Heerwagen by observing that it overstated the adverse implications of applying a standard of

14 proof less stringent than that of preponderance of the evidence. In re IPO, 471 F. 3d at 37 n.8. 9

15 Neither of the statements in In re IPO can bear the weight that Teamsters would place on them. 
13

1 Second, Teamsters argues that the district court should not have applied the

2 preponderance of the evidence standard without granting it the opportunity to conduct further

3 discovery and a full evidentiary hearing on the issue of the efficiency of the Certificates’ market. 

4 Teamsters did not request an evidentiary hearing in its motion for class certification, its

5 withdrawn motion for reconsideration, or its motion for leave to appeal to this Court. It

6 nevertheless contends now that “[w]here a district court decides not to hold a ‘full blown

7 evidentiary hearing,’ as is the case here, the prima facie standard should be applied[,]” similar to

8 what is employed when deciding issues of personal jurisdiction without an evidentiary hearing. 

9 It relies on our statement in In re IPO that “[t]he Rule 23 requirements are threshold issues,

10 similar in some respects to preliminary issues such as personal or subject matter jurisdiction.” 

11 Id. at 40.

12 We find this argument unconvincing. In requiring courts “to assess all of the relevant

13 evidence admitted at the class certification stage,” to “resolve[] factual disputes relevant to each

14 Rule 23 requirement,” and to “find[] that whatever underlying facts are relevant to a particular

15 Rule 23 requirement have been established,” we did not prescribe any particular way of

16 proceeding. Id. at 41-42. To the contrary, we emphasized that district courts retain “ample

17 discretion” to limit discovery and “the extent of the hearing” on Rule 23 issues “in order to

18 assure that a class certification motion does not become a pretext for a partial trial of the merits.” 

19 Id. at 41; see also Heerwagen, 435 F.3d at 233 (noting that “[t]he amount of discovery” granted

20 on class certification issues “is generally left to the trial court’s considerable discretion”). We

21 require only that a court “receive enough evidence, by affidavits, documents, or testimony, to be
 Teamsters makes this request on the ground that it signaled to the district court that it 10

had “moved for class certification reasonably believing that its partial record of Certificate

efficiency would be adjudged against the lesser ‘some showing’ standard.” 

14

1 satisfied that each Rule 23 requirement has been met.” In re IPO, 471 F.3d at 41.

2 For the same reasons, we also deny Teamsters’ request to remand to permit additional

3 discovery on class certification issues in the event that the preponderance of the evidence

4 standard is held to apply. Teamsters waited four months after the district court’s denial of its 10

5 class certification motion and stay of discovery, and several months after we granted leave to

6 appeal, to request additional discovery from the district court. Because it did not seek, and we

7 did not grant, leave to appeal the district court’s January 2007 decision denying the request, we

8 are not required to consider whether additional discovery is warranted. In any event, we note that

9 the district court’s denial of the request did not abuse its broad discretion to direct and manage

10 discovery. Wills, 379 F.3d at 41.

11

12 B. Factual Findings

13 Based on its consideration of five of the eight Cammer factors, the district court found

14 that Teamsters failed to show by a preponderance of the evidence that the Certificates traded in

15 an efficient market—one in which the prices of the Certificates incorporate most public

16 information rapidly—and was therefore unable to rely on the fraud-on-the-market presumption of

17 reliance. Teamsters, 2006 WL 2161887, at *10-12. Teamsters contends that the district court

18 abused its discretion when determining that the Certificates traded in an inefficient market by
Teamsters does not contest the district court’s consideration of the Cammer factors, but 11

only the determination that the factors weigh in favor of a finding of Certificate market

inefficiency. The Cammer factors have been routinely applied by district courts considering the

efficiency of equity markets. At least one court has applied them to bond markets with a

recognition of the differences between the manner in which debt bonds and equity securities

trade. In re Enron Corp. Sec., 529 F. Supp. 2d 644, 748 (S.D. Tex. 2006). This Court has not

adopted a test for the market efficiency of stocks or bonds, and we do not do so here.

15

1 making clearly erroneous factual findings relating to three Cammer factors: (1) that analysts did

2 not cover or report on the Certificates, (2) that there were no firms making a market in the bonds,

3 and (3) that the empirical data did not demonstrate a causal relationship between unexpected,

4 material information and the Certificates’ prices.

11

5

6 1. Analyst Coverage of the Certificates

7 According to Cammer, the existence of a number of financial analysts who report on a

8 security supports a finding of market efficiency because it permits an inference that financial

9 statements relating to a security are “closely reviewed by investment professionals, who . . . in

10 turn make buy/sell recommendations to client investors.” Cammer, 711 F. Supp. at 1286; accord

11 In re Xcelera.com Sec. Litig., 430 F.3d 503, 514 (1st Cir. 2005) (“Both parties agree that the

12 greater the number of securities analysts following and reporting on a company’s stock, the

13 greater the likelihood that information released by a company is being relied upon by

14 investors.”).

15 Teamsters argued to the district court that the “analyst coverage” factor supports a finding

16 that the Certificates traded in an efficient market for two main reasons. First, its expert, Dr. Tavy
16

1 Ronen, attested that forty-four individual analysts from twenty-eight firms specifically reported

2 on BI during the class period. Ronen Supp. Aff. ¶ 21. She reasoned that “[s]ince the Certificates

3 are backed by loans that were purchased by a division of Bombardier, Inc., and since analysts

4 provided information on BI as a whole, including any material information on its divisions,

5 Certificate investors had a strong base of information to draw upon in determining the price of

6 the Certificates.” Id. Ronen also attested that BI and BCI “were integrated in the servicing of the

7 Certificates[,] and had arranged for financing into the Certificates,” which meant that “any news

8 affecting their financial health and hence ability to continue supporting/servicing these

9 Certificates would be expected to impact the investors.” Ronen Reply Aff. ¶ 22. Second, Ronen

10 pointed to the fact that the three major bond rating agencies—Fitch, Moody’s Investors Service

11 and Standard & Poor’s—rated the Certificates, which also helped Certificate prices reflect

12 material information about BI and BCI. Ronen Supp. Aff. ¶ 21.

13 The appellees disputed these arguments. Their expert, Andrew Carron, contended that

14 the activities of analysts who followed BI were irrelevant because the Certificates were not BI

15 debt securities. Carron Aff. ¶ 39. He also argued that Teamsters failed to show that analysts

16 specifically followed the Certificates themselves and criticized Ronen’s reliance on rating agency

17 activity. Id. Analyzing the frequency of transactions and average price of transactions in the

18 Certificates on days following three specific instances in which the credit rating of the

19 Certificates was changed, Carron concluded that “[e]ither there [is] insufficient data to determine

20 whether the Certificate prices reflected the credit analyst coverage,” or “Certificate prices did not
While a favorable rating by one of the three major bond rating agencies may “make[] it 12

easier to sell the security to investors, who rely upon [the rating agency’s] analysis and

evaluation,” Am. Sav. Bank, FSB v. UBS PaineWebber, Inc. (In re Fitch, Inc.), 330 F.3d 104, 106

(2d Cir. 2003), there are reasons why a district court may conclude that rating agencies less

directly impact the price of bonds in comparison to analysts who follow an equity, directly relate

information to buyers, and engage in the act of selling. See Randall S. Thomas & James F.

Cotter, Measuring Securities Market Efficiency in the Regulatory Setting, 63-SUM Law &

1 react in a consistent manner, indicating that the market was not efficient.” Carron Aff. ¶¶ 42-44,

2 Ex. 11-12. 

3 The district court found that “Teamsters . . . presented no evidence that analysts

4 specifically followed the Certificates, the value of which is tied to the performance of the

5 underlying mobile homes, and only incidentally to the performance of BI or its subsidiaries.” 

6 Teamsters, 2006 WL 2161887, at *10. On this ground, the district court determined that a lack

7 of analyst coverage indicated that the market was inefficient. Id. We find no error in this

8 determination. Contrary to Teamsters’ claims, the district court did not disregard its evidence on

9 this point. Rather, it acknowledged Ronen’s opinion that the forty-four “analysts who followed

10 BI followed the Certificates as well” because “BCI was servicing the collateral for the

11 Certificates, and because BI financially supported BCI.” Id. The district court simply found

12 Ronen’s account unpersuasive and instead accepted Carron’s reasoning that there were no

13 analysts who specifically followed the Certificates. Moreover, although the district court did not

14 address the question of whether the three major bond rating agencies promoted the efficiency of

15 the Certificate market in a manner akin to that of analysts reporting on equities, it was not

16 required to do so in light of the compelling reasons in the record for rejecting such an analogy.12
Contemp. Probs. 105, 113-14 (2000) (concluding that rating agencies are not analogous to “sellside equity analysts” who follow equities, publish their research and earnings estimates, and

“provid[e] a valuable conduit for information to pass from companies to investors”).

1 2. Market Makers

2 Market makers promote the efficiency of a security’s market because they “react swiftly

3 to company news and reported financial results by buying or selling stock and driving it to a

4 changed price level.” Cammer, 711 F. Supp. at 1287. We begin with the SEC’s definition of a

5 “market maker” as 

6 a dealer who, with respect to a particular security, (i) regularly publishes bona fide,

7 competitive bid and offer quotations in a recognized interdealer quotation system; or (ii)

8 furnishes bona fide competitive bid and offer quotations on request; and, (iii) is ready,

9 willing and able to effect transactions in reasonable quantities at his quoted prices with

10 other brokers or dealers.

11

12 17 C.F.R. § 240.15c3-1[c]8 (2006).

13 Teamsters made three main arguments in support of its claim that market makers for the

14 Certificates existed. First, its expert opined that the lead underwriters of each class of the

15 Certificates acted as market makers because the Certificates are analogous to equity IPOs. Ronen

16 Supp. Aff. ¶ 24. Second, based on her analysis of trading records, Ronen concluded that a

17 number of additional firms that were not underwriters also served as market makers. Id. Third,

18 Joseph McAdams, the bond trader for Teamsters’ investment advisor, testified that he “[felt]

19 confident” that on any given day during the class period, he could have obtained a quote from

20 any one of a number of broker-dealers. McAdams also testified that between 2002 and 2005, he

21 “was aware of specific bids or offers” for the Certificates, and that he believed that “[t]here were
19

1 six to seven dealers that . . . have been and did continue to be active in the manufactured housing

2 market.” 

3 The appellees, relying on Carron’s affidavit, disputed the existence of market makers for

4 the Certificates. He attested that a market maker is by definition an entity that “commit[s] to buy

5 (bids) and to sell (offers) the security at specified prices.” Carron Aff. ¶ 46. Carron faulted

6 Ronen’s study identifying six non-underwriter market makers because it was based on

7 transaction data that did not demonstrate that the firms actually made “active bids/offers.” Id.

8 The district court concluded that Teamsters did not demonstrate that any firm “regularly

9 publish[ed] bids and quotes for the Certificates,” or that any firm “would furnish bids and quotes

10 on request and . . . would effect transactions for each Certificate.” Teamsters, 2006 WL

11 2161887, at *11. It also rejected Ronen’s argument that the lead underwriter acted as a market

12 maker for the Certificates because the Certificates were analogous to equity IPOs. Id. The

13 district court believed that Teamsters should have, but did not, “independently” show that the

14 Certificate market was efficient. Id.

15 This finding was not erroneous. The district court considered Teamsters’ evidence and

16 found that it failed to show that firms engaged in either of the two activities identified by the

17 SEC as defining a market maker. Id. Although Ronen attested that both underwriters and non18 underwriters made a market in the Certificates, according to Carron, the limited trading data on

19 which her conclusion was based did not indicate that the firms actually furnished bids or quotes

20 on request, or were ready, willing, and able to effect transactions in the Certificates. Moreover,
13 McAdams’ expression of general confidence that he could have obtained a quote from

several broker-dealers during the class period and that he believed there were firms that were

“active” in mobile home-backed securities does not show that firms actually furnished bids and

offered quotations on request, or were ready, willing, and able to effect transactions in the

Certificates. He failed to identify any of the firms that purportedly made specific bids or offers

for the Certificates during the class period and only testified to obtaining an actual bid or quote

after the close of the class period.

 Teamsters argues that the district court erred when it found that the absence of firms

14

that “regularly publish[ed]” bids and quotes for the Certificates favored a finding of market

inefficiency because bond markets differ from equity markets in that no entities regularly publish

bond bids and quotes. We need not address this argument here, where the district court based its

market maker finding on considerably more than the absence of the regular publication of bids

and quotes for the Certificates.

20

1 although the district court did not mention McAdams’ testimony on the issue of market makers,

2 there was no need for it to do so. Nothing in his testimony compelled a finding that there were

3 firms that actually furnished bids and offered quotations on request, or were prepared to effect

4 transactions in the Certificates the way that market makers would have done. Teamsters has not 13

5 pointed us to evidence that would compel a different finding.14

7 3. Proof of Causation

8 Evidence that unexpected corporate events or financial releases cause an immediate

9 response in the price of a security has been considered “the most important[] Cammer factor,” In

10 re Xcelera.com, 430 F.3d at 512, and “the essence of an efficient market and the foundation for

11 the fraud on the market theory,” Cammer, 711 F. Supp. at 1287. Without the demonstration of

12 such a causal relationship, it is difficult to presume that the market will integrate the release of
 An event study may be rejected, however, if it is methodologically unsound or 15

unreliable. See, e.g., Bell v. Ascendant Solutions, Inc., 422 F.3d 307, 316 (5th Cir 2005).

21

1 material information about a security into its price. An event study that correlates the disclosures

2 of unanticipated, material information about a security with corresponding fluctuations in price

3 has been considered prima facie evidence of the existence of such a causal relationship. See,

4 e.g., In re Xcelera.com, 430 F.3d at 512-14, 516.15

5 Teamsters proffered an event study prepared by its expert, which purportedly

6 demonstrated that the release of unanticipated, material information in December 2002 and

7 March 2003 was associated with subsequent fluctuations in Certificate prices and “excess”

8 returns. Teamsters, 2006 WL 2161887, at *11; Ronen Supp. Aff. ¶ 27 & Ex. G. Ronen used

9 prices for different classes of Certificates that were reported daily by the Financial Times (“FTIM

10 prices”) for the relevant portions of the study. Ronen Supp. Aff. ¶ 27; Ronen Reply Aff. ¶ 15(b). 

11 Unlike Certificate transaction prices, FTIM prices and other so-called “matrix” prices, are

12 adjusted daily pursuant to proprietary models to reflect market conditions. Ronen offered the

13 following justification for their use in the study:

14 [M]anually adjusted prices in the absence of public trading data are a meaningful

15 indicator of market efficiency. Transaction prices for publicly traded instruments mostly

16 incorporate information provided by analysts, who predict prices, earnings, and other

17 pertinent information. Similarly, Bloomberg and other pricing services perform the role

18 of analysts when there are no publicly available prices. Hence, their “indications”

19 constitute a reasonable proxy for transaction prices, and an event study conducted on the

20 basis of these prices is reasonable and meaningful.

21

22 Ronen Reply Aff. ¶ 15(b). 
Carron also argued that Bloomberg prices for the Certificates “did not change for many 16

consecutive days,” which “indicate[d] conclusively that either Bloomberg prices are not reliable

and/or the market for the Certificates is not efficient.” Carron Aff. ¶ 30. 

22

1 The appellees challenged the study on several grounds. First, their expert contended that

2 the study was flawed because it sought to measure the impact of immaterial information—

3 disclosures about BI—on Certificate prices. Carron Aff. ¶ 28. Second, Carron argued that the

4 integrity of the study was impaired because it relied on Bloomberg prices for the Certificates

5 rather than transaction prices. Id. ¶30. Contending that Bloomberg prices “are different from

6 transaction prices,” and that “[t]here is much greater variation in transaction prices than in

7 Bloomberg prices,” he concluded that “[to] conduct an event study using manually adjusted

8 prices is unsound.” Id. ¶¶ 30, 33. Third, Carron contended that trading data for the Certificates 16

9 contradicted the results of the event study because analysis of “all [of] the transactions in every

10 tranche of the Certificates in the period from December 1, 2002 through March 31, 2003,”

11 revealed that “[t]he tranches were either not traded or there were no material price declines

12 around the alleged disclosure dates.” Id. ¶ 37.

13 The district court rejected Ronen’s event study for two reasons. First, it faulted the

14 purported use of Bloomberg prices, reasoning that

15 [b]ecause Bloomberg and other proprietary pricing services presuppose that security

16 prices reflect information about the company (or, in this case, the Certificate collateral),

17 these “prices” assume market efficiency. To use prices that assume market efficiency in

18 an event study designed to determine whether or not that market is efficient is circular

19 reasoning. Where Bloomberg prices materially differ from transaction prices, as they do

20 here, event studies must use transaction prices.
The district court reasoned that “[t]he news analyzed in event studies must relate to the 17

underlying financial health of the Certificates—news relating to BI generally is not sufficiently

material to the financial health of the mobile home installment sales contracts and mortgage

loans that constitute the Certificates’ collateral.” Teamsters, 2006 WL 2161887, at *11.

23

1 Teamsters, 2006 WL 2161887, at *11. Second, the district court criticized the study for

2 measuring “price reactions to news solely concerning the financial health of BI, not its mortgage

3 division,” concluding that information about BI itself was not “sufficiently material” to the

4 Certificates’ collateral. Id. After rejecting the event study, the district court found that

17

5 Certificate transaction prices actually “reacted weakly to unexpected downgrades” of the

6 Certificates, which demonstrated market inefficiency. Id. at *12.

7 The district court erred when it found that the study used Bloomberg prices. It is clear

8 that the pertinent portion of the event study exclusively used FTIM prices. See Ronen Reply Aff.

9 ¶ 15(b). This error is not material in and of itself. If the district court meant to indicate that its

10 first ground for rejecting the event study was the study’s use of FTIM prices, we are

11 uncomfortable with this conclusion. We believe the district court overlooked compelling

12 evidence demonstrating that, notwithstanding material differences between FTIM and transaction

13 prices, FTIM prices may be legitimately used in an event study. Ronen explained that because

14 price changes are the focus of an event study, matrix prices may be used as long as they are

15 shown to be consistent and reliable proxies for transaction prices. Ronen Reply Aff. ¶ 15 (a), (e). 

16 Appellees never seriously challenged this argument. Ronen also provided well-conceived,

17 empirical studies demonstrating that FTIM prices were consistent and reliable proxies because
 Ronen further demonstrated that Carron’s own study attempting to show that

18

Bloomberg prices were not reliable proxies was flawed; that he overstated differences in the

movement of FTIM and transaction prices during the relevant periods; and that he erred when he

concluded that “Bloomberg prices and transaction prices often moved in different directions.”

See Carron Aff. Ex. 6a-c; Ronen Reply Aff ¶ 17-19, Ex. 4-5.

 The district court also incorrectly characterized one of Carron’s findings by stating that

19

“[a]fter analyzing both Bloomberg prices and transaction prices for the Certificates, Carron

concludes that Bloomberg prices experienced greater variation over time than transaction prices.” 

Teamsters, 2006 WL 2161887, at *11. This finding reversed Carron’s actual conclusion, see

Carron Aff. ¶ 33, but is not, in and of itself, a material error.

24

1 FTIM, Bloomberg, and transaction prices generally moved in the same direction during the

2 months close to the disclosure dates studied. See Ronen Reply Aff. ¶16, 19, Ex. 3-5. In light of 18

3 this record, we believe it was unsound to conclude that the fact that there were material

4 differences in the values of FTIM and transaction prices prohibited the use of FTIM prices in the

5 study.19

6 The district court’s ultimate determination that the event study did not support a finding

7 of market efficiency was not clearly erroneous, however, because of the soundness of the second

8 ground for its rejection of the study: the study’s focus on the disclosure of information

9 immaterial to the Certificates, principally news relating to BI. Teamsters, 2006 WL 2161887, at

10 *11. The disclosures made in December 2002 and March 2003, which were relied on by

11 Teamsters’ expert, refer to BI’s “goodwill writeoff,” the inclusion of BCI in these writedowns,

12 and “the challenges facing [BI’s] lending unit.” The district court was not compelled, however,

13 to find that these disclosures conveyed material information to Certificate investors. The
25

1 disclosures may have aptly highlighted the troubles of BI and suggested that BCI would be

2 impacted as a result. None of them, however, connected these problems to the mobile home

3 loans or contracts forming the Certificate collateral or suggested that projected BI writedowns

4 would compromise BI or BCI’s ability to extend credit to support the Certificates. Nor does

5 Teamsters’ contention that information released before the December 2002 articles primed the

6 market so that the information conveyed in later disclosures was material to the Certificates. 

7 Since the district court correctly concluded that the disclosures studied were immaterial, any

8 fluctuations in the Certificates’ prices documented by the event study could not reasonably be

9 interpreted to reflect market efficiency. Consequently, the district court did not err in rejecting

10 the study as proof of causation.

11 Moreover, the district court’s additional determination that the empirical data actually

12 supported a finding of market inefficiency because “[t]here were no material price drops in the

13 Certificates after they were downgraded below investment grade in December 2002 and February

14 2003” and because “transaction prices . . . reacted weakly to unexpected downgrades” was well

15 grounded in the record. Id. at *12. Teamsters’ contentions to the contrary—that BI and BCI

16 historically provided direct financial support to the Certificate collateral so as to preclude any

17 Certificate price declines in reaction to downgrades and that there were nevertheless “precipitous

18 price reactions a few days later when there was news of further anticipated substantial BI and

19 BCI manufactured housing asset write-downs”—are unsupported by the record. 

20
26

1 4. Finding of Market Inefficiency

2 After analyzing the Cammer factors, the district court concluded that three of them—the

3 absence of market makers for the Certificates, the lack of analysts following the Certificates, and

4 the absence of proof that unanticipated, material information caused changes in the Certificates’

5 prices—as well as the infrequency of trades in the Certificates “all tend to establish the

6 inefficiency of the Certificate market” and prevent Teamsters from relying on the fraud-on-the7 market presumption. Id. Teamsters challenges this conclusion on the ground that the district

8 court ignored fundamental differences in the way stocks and bonds are traded.

9 We are mindful of one court’s observation “that a comparison between equity and bond

10 markets is a comparison between the proverbial apple and orange” and that

11 denying [the] application of fraud on the market to the bond market because it does not

12 operate in the same way as a national exchange or trade in the same volume, frequency,

13 or manner as equity on those exchanges is throwing out oranges because they are not

14 apples. 

15 In re Enron, 529 F. Supp. 2d. at 755, 768. We conclude, however, that the district court properly

16 used the Cammer factors as an “analytical tool,” Unger v. Amedisys Inc., 401 F.3d 316, 325 (5th

17 Cir. 2005), and made no clear error in determining that Teamsters failed to show by a

18 preponderance of the evidence that the Certificates traded in an efficient market. In view of this

19 conclusion, we do not have occasion to address the nettlesome question of whether, for the

20 purposes of determining the applicability of the fraud-on-the-market doctrine, an adjusted set of

21 Cammer factors or even a different analytical approach altogether is better suited to analyze
27

1 market efficiency in securities cases arising from the sale of debt instruments.

3 CONCLUSION

4 The decision of the district court is affirmed.
