Abstract
This piece argues that both the efficient market requirement and event study methodology—once the core of the fraud-on-the-market theory—have evolved in securities fraud class actions. It provides the first comprehensive analysis of fraud-on-the-market cases over the past fifty years and divides this evolution into five chronological stages.
