MEMORANDUM DECISION
This is plaintiffs’ renewed motion for class action determination pursuant to Rule 23(b)(3) of the Federal Rules of Civil Procedure.
An earlier motion seeking similar relief was denied by the court on September 8, 1975 upon a finding that the requisite degree of numerosity had not been demonstrated.1 68 F.R.D. 281 (S.D.N.Y.1975). At that time, the court held that an increase in the number of shares of Electrospace common stock outstanding and a decrease in the number of debenture holders of record during part of the period for which class action determination was sought did not warrant the assumption that the proposed class of aggrieved share and debenture holders numbered in the thousands. The court, therefore, also declined to resolve questions concerning (1) the adequacy of representation which the representative plaintiffs and their counsel would afford the class, (2) the predominance of common questions of law or fact over individual questions, (3) the superiority of the class action device over other methods of adjudication, and (4) the proper scope of the class to be conditionally certified.
*42The class proposed consists of all persons, except defendants and their privies, who purchased Electrospace common stock or SVh percent convertible subordinated debentures due October 1, 1983 during the period from January 1, 1972 through April 26, 1974, and who either retain their securities or sold them at a loss.
I
a. Numerosity. With respect to the question of numerosity, the weekly trading figures for Electrospaee common stock show that 3,102,200 shares of stock were traded from January 1, 1972 through March 11, 1974.2 Thus, if the average purchaser acquired 200 shares during the relevant period, the class would consist of approximately 15,200 present and former Electrospace shareholders.3 Moreover, the sales figures for Electrospace convertible debentures suggest that there are also approximately 650 debenture holders in the proposed class,4 if it is assumed that the average debenture holder acquired ten debentures during the relevant period.5
The court considers the assumptions behind these calculations to be rationally based. Therefore, since the defendants offer no evidence that the plaintiffs’ reasoned estimates misrepresent the actual size of the class, I find joinder of all class members to be impracticable.6
b. Representativeness. In considering the original motion for class action determination, the court observed that the named plaintiffs had a strong interest in advancing their claims which made them fit representatives for the purported class. It also found their counsel to be amply qualified to pursue a recovery on behalf of a class. But contrary to the assumption evidenced in the affidavit of I. Stephen Rabin, Esq., lead counsel for the plaintiffs, these observations were not dispositive of the fourth requirement for class action certification, namely that the plaintiffs fairly and adequately represent the class. Rather, “the financial ability of the representative parties to pay *43for notice to the class and other costs of litigation is also relevant.” 68 F.R.D. at 286-87.
At the request of the court, Mr. Rabin recently submitted an in camera affidavit detailing the anticipated costs of prosecuting this action on behalf of the class proposed. After examination of that affidavit, the court is persuaded that the representative plaintiffs have sufficient interest and financial wherewithal to adequately represent a class, and that the expenses of litigation will ultimately be borne by the appropriate parties. The court therefore finds the proposed class representatives and their counsel to be proper advocates for the class.
c. Predominance of Common Questions. While the court’s earlier opinion also identified some of the questions of law or fact common to the class, it deferred consideration of whether those questions would predominate over questions affecting only individual class members until such time as the numerosity requirement was met. Not unexpectedly, the defendants now contend that even if numerosity has been demonstrated, individual questions will predominate since purported class members purchased their securities in a steadily declining market and, therefore, as a group could not have relied upon the misrepresentations or omissions alleged in the complaint in making their purchases. Defendants argue that each class member will have to show that he himself relied upon material misrepresentations or omissions by the defendants in order to establish a cause of action and damages under the securities law. See Note of the Advisory Committee on Rules, 1966 Amendment to Rule 23, Federal Rules of Civil Procedure. They further contend that “dramatic” differences among the misrepresentations alleged for different years will also increase the importance of the individual issues to be litigated at trial.
In the first instance, the court notes that the question of whether reliance may be shown by market impact rather than more traditional methods of proof is itself a question common to all members of the class. Gold v. DCL, Inc., 399 F.Supp. 1123, 1129 (S.D.N.Y.1973). However, even if it is assumed, arguendo, that this is not a “market impact” case, plaintiffs have alleged a continuing course of fraudulent misconduct which will clearly be the predominant issue for the trier of fact to resolve at trial. I therefore find that the common questions in this action will necessarily predominate over those concerning only individual members of the class.7 See Aboudi v. Daroff, 65 F.R.D. 388, 392-93 (S.D.N.Y.1974).
d. Superiority of Class Action. Finally, the court finds that prosecution of this action on behalf of a class is far superior to other available methods for adjudication of the controversy. Both the predominance of common questions and the need to aggregate a series of relatively small claims8 in order to prosecute this action efficiently make other methods of litigation impracticable. Moreover, there is no evidence that individual members of the purported class would want to attempt recovery in separate actions, nor are there other related actions pending against the defendants here. It is therefore in the interest of efficient husbandry of judicial resources to try all claims raised in the consolidated complaint before one court and to have representative plaintiffs proceed on behalf of a class.
II
The arguments advanced by defendants with respect to definition of the class may *44be dealt with summarily. First, even though the Electrospace audited financial statement for the year ended December 31, 1971 was not published until April 18, 1972, the 'Consolidated complaint alleges that misleading financial information concerning the firm was disseminated in early January of 1972. Beginning the class period as of January 1, 1972 is therefore proper. Similarly, while the Internal Revenue Service publicly issued a report in September of 1973 proposing adjustments to prior Electrospace tax returns which would have led to the assessment of deficiencies, and despite Electrospace’s disclosure to the SEC in December of 1973 that it had materially overstated net income in prior financial statements, the consolidated complaint alleges that other material misstatements or omissions by one or more defendants went uncorrected until April 26, 1974, the date that Electrospace filed under Chapter XI of the Bankruptcy Act. Thus, there is also no reason to end the class period before April 26, 1974.
The requested class will therefore be conditionally certified pursuant to Rule 23(b)(3). It is, of course, subject to refinement or modification should this prove necessary as the action moves forward.
Within 20 days from the entry of this decision, plaintiffs are to submit an order together with a form of notice and form of exclusion request in accordance with section 1.45 of the Manual for Complex Litigation (3d ed. 1973) and the forms related thereto. Said order is to provide for notice to the class within 30 days from the date it is entered.
SO ORDERED.
