Filings

The Stanford Law School Securities Class Action Clearinghouse in cooperation with Cornerstone Research publishes a series of reports on securities class actions filed after the passage of the Private Securities Litigation Reform Act of 1995 (PSLRA or Reform Act). These reports are widely cited, providing comprehensive statistics on historical and recent filings activity, characteristics, and trends.

Settlements

Cornerstone Research has developed a database of securities class actions filed after the PSLRA and settled from 1996 through 2015. As of December 2015, this database includes 1,537 securities class actions and more than 60 variables.
