This is a federal securities class action brought on behalf of investors against Trevena, Inc. and its former executives for violations of §§ 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended by the Private Securities Litigation Reform Act of 1995 ("PSLRA"), 15 U.S.C. §§ 78j(b) and 78t(a), and Rule 10b-5 promulgated thereunder, *41117 C.F.R. § 240.10b-5.1 As lead plaintiff and lead counsel must be appointed pursuant to 15 U.S.C. § 78u-4, Plaintiffs Huseyin Erenoglu, a group of five individual members2 (collectively, "Trevena Group"), and Lanphie Ping have each moved for such appointment and for approval of their choice of lead counsel.3 Upon consideration of the motions, the responses thereto, and the oral arguments presented at a hearing held on February 20, 2019, the Court determines that Trevena Group shall be appointed as lead plaintiff for the class and approves of Block & Leviton LLP as its choice of lead counsel and Kaufman Coren & Ress, P.C. as liaison counsel, for the following reasons.
I. BACKGROUND4
Trevena is a clinical stage biopharmaceutical company that discovers, develops, and seeks to commercialize therapeutics by utilizing a novel approach to treating moderate to severe acute pain intravenously. Trevena allegedly issued a press release on May 2, 2016, announcing that it had reached a general agreement with the FDA on key elements of its clinical development program for one of its products, Olinvo (oliceridine). Based on those statements and omissions as to the strength of the program, the design of its Phase III trial, and its prospects for obtaining FDA approval, the price of Trevena's stock began to increase. On October 9, 2018, however, two days before the FDA would meet with Trevena to determine whether Olinvo would be granted approval, the FDA publicized a briefing document which contained minutes from its 2016 meeting with Trevena that it previously criticized the design of the Phase III trial and that the FDA's Advisory Committee was recommending rejection of Olinvo's new drug application. As a result, the price of Trevena's stock dropped 64% by the time the market closed on October 9. Plaintiffs are comprised of investors who purchased Trevena common stock between May 2, 2016 and October 8, 2018 (the "Class Period").
The Court has previously consolidated the three separate lawsuits against Trevena and its former executives, and now must decide whether Erenoglu, Trevena Group, or Ping will serve as lead plaintiff. A hearing was held on February 20, 2019, after which the Court required Erenoglu to produce his trade confirmations from the Class Period to the Court and to the other Moving Plaintiffs, and permitted further briefing upon receipt of the trade confirmations.5
II. PROCEDURAL REQUIREMENTS
The PSLRA requires that within 20 days of filing a complaint, the plaintiff must "cause to be published, in a widely circulated national business-oriented publication or wire service," notice to members of the purported class as to "the pendency of the action, the claims asserted therein, and the purported class period."6 Within 60 days of the date on which the notice is *412published, "any member of the purported class may move the court to serve as lead plaintiff of the purported class."7
On October 11, 2018, one day after the Complaint was filed, a notice of the pendency of this action was published on PR Newswire , a national business-oriented newswire service.8 On December 10, 2018, 60 days after the notification release, Erenoglu, Trevena Group, and Ping each filed timely motions to serve as lead plaintiff, and for appointment of lead counsel for the class.9
III. LEGAL STANDARD
Under the PSLRA, the court must appoint a lead plaintiff "as soon as practicable" after a class action securities lawsuit has been consolidated.10 The presumptive lead plaintiff is the investor with the largest financial interest in the outcome of the action, as long as that investor satisfies the following Federal Rule of Civil Procedure 23 requirements: (1) the claims must be typical of and share common questions of law with the claims of the absent class members, and (2) the investor must adequately represent the interests of the entire class.11
The presumption "may be rebutted only upon proof by a member of the purported plaintiff class that the presumptively most adequate plaintiff" either: (1) "will not fairly and adequately protect the interests of the class"; or (2) "is subject to unique defenses that render such plaintiff incapable of adequately representing the class."12 If the court finds, for any reason, that the movant with the largest loss cannot make a threshold showing of typicality and adequacy, the court must explain its reasons, disqualify that movant, and "then identify the movant with the next largest loss, consider whether that movant satisfies Rule 23's requirements, and repeat this process until a presumptive lead plaintiff is identified."13
IV. DISCUSSION
A. Largest Financial Loss
The three relevant factors when analyzing the largest financial interest are: (1) the number of shares purchased during the class period; (2) the total net funds expended by the plaintiffs during the class period; and (3) the approximate losses suffered by the plaintiffs.14 The third factor-the approximate losses suffered-has been considered by courts within this Circuit to be the most significant in the context of *413securities litigation.15
Erenoglu alleges that he suffered the greatest financial loss of $ 552,075.43.16 Both Trevena Group and Ping have contested this calculation in their briefs and during the hearing. Erenoglu was ordered to produce his trade confirmations,17 which revealed that Erenoglu had overstated his total losses by $ 518.61. Nevertheless, for purposes of the largest financial interest, Erenoglu still retains the largest financial interest of the Moving Plaintiffs in this case,18 as Trevena Group's five members show aggregated total losses of approximately $ 485,972.97,19 and Lanphie Ping lost $ 205,654.53.20
B. Rule 23 Requirements
Typicality is not a concern here, as all Moving Plaintiffs have established that their claims "arise[ ] from the same event or practice or course of conduct that gives rise to the claims of other class members, and [ ] is based on the same legal theory."21 However, Moving Plaintiffs dispute whether the other Plaintiffs can establish adequacy of representation for the class. Determining "adequacy" requires courts to consider: (1) whether the potential representative "has the ability and incentive to represent the claims of the class vigorously;" (2) whether the potential representative "has obtained adequate counsel;" (3) whether "there is [a] conflict between [the movant's] claims and those asserted on behalf of the class;" and (4) "whether the movant has demonstrated a willingness and ability to select competent class counsel and to negotiate a reasonable retainer agreement with that counsel."22 The court must review the pleadings filed, the movant's application, and any other information that has been submitted.23
1. Huseyin Erenoglu
As the investor with the largest financial loss, Huseyin Erenoglu asserts that his similar interests with those of the class in recovering a maximum amount of damages, his lack of conflict in his adequacy to represent the class, and his choice of counsel *414render him the prevailing lead plaintiff. Erenoglu has submitted a declaration stating that he resides in the United States, independently seeks appointment as lead plaintiff, and understands the requirements to serve as lead plaintiff and is willing to do so.24
The other Moving Plaintiffs argue that there are errors in Erenoglu's sworn certifications and declarations when compared to his trade confirmations, and that although Erenoglu's certification and declaration accurately reflect the number of shares purchased and sold, they do not accurately reflect the number of trades and the price per share. Instead, as Erenoglu admits, he combined certain trades and averaged the per-share prices, overstating his total losses by $ 518.61.25 Additionally, the other Moving Plaintiffs point to the fact that Erenoglu misstated the date on which some of the shares of common stock were purchased, which Erenoglu also concedes.26 According to the other Moving Plaintiffs, the errors in his sworn statements highlight issues of carelessness, which undermine his adequacy to serve the class as lead plaintiff.
The Court agrees with the other Moving Plaintiffs that the errors in Erenoglu's sworn statements amount to a substantial degree of carelessness and raise doubt as to whether he will fairly and adequately represent the best interests of the class. Sworn declarations are integral to the PSLRA process, as they assure district courts that the proposed plaintiff (1) has suffered financial harm; (2) is not a serial litigant; and (3) is interested and able to serve as lead plaintiff.27 Although Erenoglu submits that his errors are minor or inadvertent mistakes in absolute terms,28 they nonetheless speak to a level of carelessness especially where the errors were repeated.29 Particularly given that *415these errors were made at the outset of the case, this causes the Court to doubt whether Erenoglu possesses the necessary adequacy and sophistication to be lead plaintiff.
2. Trevena Group
Trevena Group comprises five individuals who lost a substantial amount of monetary funds, and who have indicated a willingness to serve the role of lead plaintiff. Because the PSLRA expressly permits groups to serve as lead plaintiff,30 Trevena Group argues that it is entitled to do so in this case.31 The five members additionally submitted a joint declaration, stating that they carefully and thoughtfully participated in a telephone conference before filing the motion and set forth various procedures and ways of communication in order to best serve the role of lead plaintiff.32 Trevena Group has selected Block & Leviton to serve as lead counsel, and Kaufman Coren & Ress, P.C. to serve as liaison counsel, both with sufficient experience in securities litigation.33
The other Moving Plaintiffs attempt to rebut Trevena Group's presumptive lead plaintiff status by contending that the group is too large, and that the lack of knowledge as to its members' pre-existing relationships raises doubt in terms of whether Trevena Group is lawyer-driven or whether its members can function cohesively and collectively as a group. The Third Circuit has indeed cautioned groups from forming based on efforts of lawyers who hope to "ensure their eventual appointment as lead counsel," and has noted that groups may sometimes be too large for its members to operate effectively as a single unit.34
The Third Circuit has agreed "with the Securities and Exchange Commission that courts should generally presume that groups with more than five members are too large to work effectively."35 The fact that Trevena Group is at the quantitative capacity of what the Third Circuit deems as adequate does not rebut the presumption of Trevena Group from becoming lead plaintiff. Although Ping argues that an individual would better serve the interests of the class than a group, "the question is not whether another movant might do a better job of protecting the interests of the class than the presumptive lead plaintiff; instead, the question is whether anyone can prove that the presumptive lead plaintiff will not do a 'fair[ ] and adequate[ ]' job."36 Thus, the size of Trevena Group does not *416make it any less viable of a candidate for lead plaintiff.
Additionally, even though the other Moving Plaintiffs speculate as to whether this geographically diverse group37 has been created by counsel or whether the group can effectively work together to become lead plaintiff, these allegations are unsupported.38 The PSLRA "contains no requirement mandating that the members of a proper group be 'related' in some manner; it requires only that any such group 'fairly and adequately protect the interests of the class.' "39 Among the many factors to consider in determining whether the movant will "fairly and adequately protect the interests of the class" are whether the individuals had a pre-existing relationship, the extent of that relationship, and whether the group was created by the efforts of lawyers for the purpose of obtaining lead plaintiff status.40 The Third Circuit has not explicitly defined what constitutes an adequate pre-existing relationship, and under the circumstances presented here, it is reasonable to conclude that a relationship based on informed communication among the members as to forming a group need only predate the motions for appointment as lead plaintiff.41
The members of Trevena Group submitted a joint declaration stating that they participated in an extensive telephone conference several days before determining that they would jointly move to become lead plaintiff.42 During this call, they thoroughly discussed the respective responsibilities of counsel and lead plaintiff, asked questions regarding the case and its possible resolution, incorporated a method of decision-making during the course of litigation, exchanged contact information with each other, and ultimately committed themselves to the zealous prosecution and oversight of the case.43 The other Moving Plaintiffs have produced no evidence, as *417opposed to merely speculation, that Trevena Group would not be able to function as a cohesive and independent group,44 or that it will not able to "fairly and adequately protect the interests of the class."45
C. Appointment of Lead Counsel
The PSLRA vests authority in the lead plaintiff to select and retain counsel, subject to the approval of the court.46 The court shall not disturb the lead plaintiff's choice of counsel unless it is "necessary to protect the interests of the class."47
Having reviewed the submissions from Trevena Group as to its selection of Block & Leviton LLP as its choice of lead counsel and Kaufman Coren & Ress, P.C. as liaison counsel, the Court finds that there is no basis to interfere with the strong presumption in favor of approving counsel.48 Both of these law firms have extensive and substantial experience in class action securities litigation, as reflected in their firm biographies which highlight their numerous successful prosecutions of such cases.49 Accordingly, the Court approves Trevena Group's selection of counsel.
V. CONCLUSION
For the foregoing reasons, Trevena Group shall be appointed as lead plaintiff for the class and its selection of Block & Leviton LLP as its choice of lead counsel and Kaufman Coren & Ress, P.C. as liaison counsel is approved. An appropriate order follows.
