IT Sector Drives Surge in US Securities Litigation Risk

A comprehensive analysis of 11,557 corporate disclosures reveals that NYSE and NASDAQ issuers suffered $17.4 trillion in market capitalization losses over the two-year period ending June 30, 2026. These losses stem from High-Risk Adverse Corporate Events, which saw a 23.4% surge in aggregate severity compared to the previous six-month reporting cycle. Nessim Mezrahi, CEO of Securities Analytics Research, noted that the rapid escalation in litigation risk reflects a systemic increase in both the frequency and financial impact of negative corporate events.

While IT remains the primary driver of market cap losses—averaging $3.39 billion per high-risk event—the risk profile is shifting across other sectors. Real Estate and Energy recorded the sharpest spikes in event frequency, rising 21.8% and 16.0% respectively. Currently, 62% of all U.S. securities litigation risk is concentrated within the Financials, Health Care, and Information Technology sectors. As market volatility persists, Health Care companies are recording the highest median risk scores, signaling that investors and legal teams should expect continued pressure on corporate transparency and disclosure accuracy.
