How the PSLRA Reshaped Securities Litigation Over 30 Years
January 28, 2026 by Michael McCreesh
It has been 30 years since the enactment of the Private Securities Litigation Reform Act (PSLRA)—a federal law that revised the rules for securities class actions. Since then, eligible investors have gained access to more than $100 billion in court-approved settlement funds across thousands of securities class actions in the United States. Three decades on, the PSLRA remains the exclusive framework for how securities class actions are filed, litigated and resolved. It has also greatly influenced how institutional investors approach participation.
Enacted in December 1995, the PSLRA was designed to address perceived and potential abuses in securities class actions. Its core reforms included:
- Heightened pleading standards for alleging securities fraud claims.
- Imposing an automatic stay of discovery while motions to dismiss are pending.
- Instituting a lead plaintiff appointment process to elicit institutional investor participation and deter quick “strike” suits.
- Establishing limits on the amount of damages a class member may recover.
Collectively, these measures were intended to curb weak or speculative claims while encouraging more substantive litigation.
Filing Trends and Case Quality
Despite early expectations, the PSLRA did not result in a sustained reduction in securities class action filings. Both pre- and post-PSLRA, an average of 200 cases or more are filed annually. Where the law has had a clear impact is on case quality. Complaints today are generally longer, more detailed and more thoroughly investigated. Accordingly, weaker claims are more likely to be dismissed at an early stage.
Notwithstanding the substantive improvements, the greater costs and effort associated with meeting heightened pleading standards may also deter some potentially meritorious cases from ever being filed. As a result, even obvious fraud cases must endure an arduous path to achieve recoveries.
Outcomes, Settlements and Investor Recovery
The PSLRA’s effect on case outcomes has been mixed. The statute has helped reduce purely nuisance claims (i.e., those lacking compelling evidence) while allowing stronger cases to proceed. As a result, of all filed securities class actions do not survive the defendant’s motion to dismiss. For claims that do survive, the litigation stakes are often higher, as over 90% of those cases will result in a settlement. Further, obtaining class certification approval and approaching a trial date can also increase in the relative size of a settlement.
This environment has produced meaningful recoveries for investors who actively participate in securities class action settlement claims filing. Investors with an outsized loss for a specific case and/or file claims in every eligible settlement can achieve significant recoveries. Consequently, informed and timely action in the claims process is critical to success.
Participation Gaps Persist
Despite the PSLRA allowing for a steady flow of securities class action settlements, a significant claims participation gap remains. In a recent ý Battea research survey, only 7% of respondents reported fully participating in all eligible securities class action settlements. Nearly 70% indicated they had explicitly or implicitly decided not to participate in claims filing at all.
The most common reason for non-participation was a perceived lack of internal expertise and concerns about upfront costs. These findings suggest that, even after 30 years, many institutional investors have yet to fully engage with the recovery opportunities the PSLRA framework enables. Lack of accurate information may also explain why investors believe there will be out-of-pocket costs when most claims-filing services only receive fees on actual recoveries.
Where the PSLRA Stands Today
Thirty years on, the PSLRA has fundamentally reshaped securities class action litigation. It hastily filed cases with a slower, more technical, higher-stakes process that benefits defendants procedurally while redefining investor protections. The statute is now the north star of securities litigation practice, influencing how counsel structure cases and how courts evaluate claims.
While debate continues over the law’s overall success, the consistent opportunity for investor recoveries remains substantial, but only for those who take action.
