This was in fact the theory behind the PSLRA’s safe harbor: the statute makes it particularly difficult for private plaintiffs to bring claims based on projections of future performance, in part because of Congress’s fear that expansive liability would dissuade issuers from making projections at all.
Two new empirical studies challenge this common wisdom.
The first, Private Litigation Costs and Voluntary Disclosure: Evidence from Foreign Cross-Listed Firms, by James P. Naughton et al., uses the Supreme Court’s decision in National Australia Bank v.
