AMENDED OPINION AND ORDER
Before the court is Plaintiffs’ Motion for Class Certification, brought pursuant to Federal Rules of Civil Procedure 23(a), 23(b)(3), and 23(c)(1). Lead Plaintiffs Monroe County Employees Retirement System (“Monroe”), Teamsters Local 408 Pension Fund (“Teamsters”), Western Pennsylvania Electrical Employees Pension Fund (“Western”), and Hawaii Reinforcing Iron Workers Pension Trust Fund (“Hawаii”), move the court for an Order certifying this case as a class action, and certifying Monroe, Teamsters, Western, and Hawaii as representatives of the class and their counsel of record as class counsel. For the following reasons, the Motion is granted.
A. Facts
Members of the proposed class in this ease are рersons and entities who purchased or otherwise acquired Aon’s publicly traded securities between May 5, 2003 through October 13, 2004 (the “Class Period”). Defendants are Aon Corporation, Patrick G. Ryan (Aon’s Chief Executive Officer and Chairman of the Board during the Class Period), Michael D. O’Halleran (Aon’s President and Chief Operating Officer during the Class Periоd), and David P. Bolger (Aon’s Executive Vice President, Chief Financial Officer, and Chief Administrative Officer during the Class Period).
Plaintiffs allege that during the Class Period, Defendants violated various provisions of the Securities Exchange Act of 1934 by deliberately or recklessly misleading the investing public about Aon’s financial condition. Specifically, Plaintiffs allеge that Defendants engaged in fraudulent “contingent commission,” “clawback,” and “bid-rigging” schemes, issued false and misleading statements, and omitted material facts about Aon’s business practices. Consolidated Compl., ¶¶ 54-104. Plaintiffs further allege that this fraudulent conduct artificially inflated Aon’s stock price to a high of $29.44 per share during the Class Periоd, and at the end of the Class Period, when Defendants’ fraudulent conduct was revealed, Aon’s stock price dropped by $8.35 per share over four days of trading. Id., ¶¶ 226-28. Thousands of similarly situated investors allegedly suffered substantial damages as a result of this precipitous drop in Aon’s stock price.
B. Procedural History
On October 25, 2004, Plaintiffs filed their initial Complaint. Then, on March 24, 2005, the court designated Monroe, Teamsters, Western, and Hawaii as the lead Plaintiffs in this action. On May 26, 2005, the Plaintiffs filed their Consolidated Complaint in the lead ease. On August 1, 2005, Defendants filed their Motion to Dismiss. The court denied the Motion to Dismiss on March 2, 2006.
Plaintiffs filed their Motion for Class Certification on May 12, 2006. Defendants filed their Memorandum in Partiаl Opposition to Plaintiffs’ Motion for Class Certification on August 11, 2006. Defendants acknowledge that the court should certify a class in this case, but assert that the Class should exclude those individuals and entities who both bought and sold Aon stock prior to the disclosures of alleged wrongdoing. Plaintiffs filed their Reply Memorandum of Law in Support of Plaintiffs’ Motiоn for Class Certification on September 8, 2006. Plaintiffs argue that the Class should include all individuals and entities who were damaged by Aon’s alleged wrongdoing during the Class Period. The Motion is fully briefed and before the court.
II. DISCUSSION
A. Standard of Decision
It is established law in the Northern District of Illinois and the Seventh Circuit that class certifications are the preferred method of dealing with securities fraud cases. “In Helfand v. Cenco, Inc.,
In order to demonstrate that class certification is appropriate in this case, Plaintiffs must satisfy all four requirements of Federal Rule of Civil Procedure 23(a). Williams v. Chartwell Fin. Servs.,
(1) the class is so numerous that joinder of all members is impracticable, (2) there are questions of law or fact common to the class, (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class, and (4) the representative parties will fairly and adequately protect the interests of the class.
Fed. R. Civ. P. 23(a); Williams,
1. 23(a)(1): Numerosity
Plaintiffs need not “state with certainty the exact number of class members, [but] they are required to base their estimate on more than mere speculation.” Fry v. UAL Corp.,
2. 23(a)(2)-(3): Commonality and Typicality
The commonality requirement is not difficult to meet. In fact, this requirement “has been characterized as a low hurdle, easily surmounted.” Scholes,
The typicality requirement is “closely related” to the issue of commonality. Id. “We have previously stated that a ‘plaintiffs claim is typical if it arises from the same event or practice or course of conduct that gives rise to the claims of other class members and his or her сlaims are based on the same legal theory.’” Id. (quoting De La Fuente v. Stokely-Van Camp, Inc.,
3. 23(a)(4): Fairness and Adequacy of Representation
To satisfy the final requirement of Rule 23(a), “the representative parties [must] fairly and adequately represent the clаss.” Rosario,
4. 23(b)(3): Predominance and Superiority
In order for a class to be certified under Rule 23(b)(3), it must meet two requirements beyond those listed in Rule 23(a): common questions of law or fact must “predominate over any questions affecting only individual members,” and class certification must be “superior” to other methods of resolving the case. Fed R. Civ. P. 23(b)(3); Amchern Prods, v. Windsor,
Determining whether [issues] common to the class predominate over individual issues requires that the court inquire how the case will be tried. This entails identifying the substantive issues that will control the outcome, assessing which issues will predominate, and then determining whether the issues are common to the class.
O’Sullivan v. Countrywide Home Loans,
Certifying a class is the “superior” way to resolve a ease where the “ ‘class action would achieve economies of time, effort, and expense, and promote ... uniformity of decision as to persons similarly situated, without sacrificing procedural fairness or bringing about other undesirable results.’ ” See Am-chem,
5. “In-and-Out” Traders and Class Action Securities Fraud Cases
In the context of securities fraud cases, “in-and-out” traders are those persons or entities who both bought and sold their shares before a company allegedly violating securities laws publicly disclosed the violations. See In re Tyco Int’l, Ltd. Multidis-trict Litigation,
The courts in these cases must therefore determine “whether in-and-out traders could conceivably satisfy the requirement of loss causation, and [should] therefore [be] included in the proposed class.” BearingPoint,
And аlthough in-and-out traders often have no associated damage because they purchased and sold at prices with the same artificial inflation, this is not always the case. In cases where, as here, there are multiple disclosures, in-and-out traders may well be able to show a loss. Moreover, it is also conceivable that the inflationary effect of a misrepresentation might well dimmish over time, even without a corrective disclosure, and thus in-and-out traders in this circumstance would be able to prove loss causation ... In sum, because in-and-out traders may conceivably prove loss causation, they are appropriately сounted as members of the proposed class.
BearingPoint,
B. Plaintiffs’ Motion for Class Certification
As the court has noted, Defendants do not dispute the general proposition that it is appropriate for the court to certify a class in this case. Plaintiffs satisfy the requirements of Rule 23(a). Plaintiffs submit, and Defendants do not dispute, that the average daily trading volume in Aon stock during the Class Period was 1.26 million shares, and that more than 280 securities firms and/or institutional investors owned Aon stock during the Class Period. The numerosity requirement of Rule 23(a) is therefore satisfied. See Fry,
In addition, Plaintiffs satisfy the requirements of Rule 23(b)(3). Common questions regarding Defendаnts’ allegedly unlawful acts and omissions, and the class members’ economic losses predominate. Should this case eventually go to trial, the court is convinced, and the parties do not dispute, that “the putative named plaintiffs can, through their individualized cases, offer proof on a class-wide basis.” See Hyderi,
[C]lass actions are often the most fair and practical vehicle for plaintiffs’ сlaims in securities fraud suits because those who have been injured are in a poor position to seek legal redress ... [B]ecause individual claims might be small in monetary value, they might not be prosecuted on an individual basis due to the costs of litigation.
Brosious v. Children’s Place Retail Stores,
The only remaining issue before the court is therefore whether the class ought to include the so-called “in-and-out” traders: those individuals or entities who both bought and sold their Aon stock prior to the end of
III. CONCLUSION
The court therefore cеrtifies the following class in this case:
All persons or entities who purchased or otherwise acquired the Common Stock of Aon Corporation (“Aon”) during the period beginning May 5, 2003 through October 13, 2004, and who were damaged thereby. Excluded from the class are: (i) Aon, (ii) Patrick G. Ryan, Michael D. O’Halleran, and David P.Bolger (collectively the “Individual Defendants”); (iii) members of the family of each Individual Defendant; (iv) any entity in which any Defendant has a controlling interest; (v) officers and directors of Aon; and (vi) the legal representatives, heirs, successors or assigns of any such excluded party.
The court designates the Monroe County Employees Retirement System, Teamsters Local 408 Pеnsion Fund, Western Pennsylvania Electrical Employees Pension Fund, and Hawaii Reinforcing Iron Workers Pension Trust Fund as class representatives, and appoints Lerach Coughlin Stoia Geller Rudman & Robbins LLP, Lasky & Rifkind, Ltd., and Vanoverbeke Michaud & Timmony, P.C., as class counsel. Pursuant to Rule 23(c)(2), the court directs Plaintiffs to file a draft of their proposed notice form on or before November 30, 2006. Defendants may file any objections to this proposed notice form on or before December 14, 2006.
IT IS SO ORDERED.
Notes
. The court notes that it also has before it the companion case of Smith v. Aon, No. 04 C 6875. In that case, Plaintiffs allege that Aon has violated various provisions of the Employee Retirement Income Security Act ("ERISA”). On April 12, 2006, the court denied Defendants’ Motion to Dismiss. A Motion for Class Certification in that case remains under advisement.
