A group of investors brings a class action lawsuit against the Z & R Accounting Firm under Section 10b and Rule 10b-5 of the 1934 Securities Act. Angela, an accountant with the firm, had done an audit of the Pennymart Inc. books. The audit failed to disclose that Orrin, the president of Pennymart, had stolen large amounts of cash from the firm. Pennymart eventually filed for bankruptcy as a result of the thefts. Can the group of investors file suit against Z & R? What is the likely result of the suit?
