United States Fifth Circuit


Oscar Private Equity Invs. v. Allegiance Telecom, Inc., 05-10791

Given the lethal force of certifying a class of purchasers of securities enabled by the fraud-on-the-market doctrine, loss causation must be established at the class certification stage by a preponderance of all admissible evidence. An order certifying a securities-fraud class action involving a now-bankrupt national telecommunications provider is vacated where plaintiffs failed to trigger the presumption of reliance provided by the fraud-on-the-market theory.
