Corning Incorporated (GLW) -13.70%

Corning disclosed an at-the-market equity distribution program permitting sales of up to $2 billion of common stock, raising dilution concerns as AI-linked optical-hardware shares were already under pressure. The company-specific financing shock made Corning the session's standout large-cap decliner and intensified selling across the optical-connectivity supply chain.

Bank of America Corporation (BAC) -5.14%

CEO Brian Moynihan projected third-quarter investment-banking fees of $1.6 billion to $1.8 billion, down from $2 billion a year earlier, and said trading revenue should be roughly flat. A management warning produced an unusually large one-day loss for a money-center bank and weighed on the broader financial sector.

A nearly 14% move on about $5.9 billion of turnover made CrowdStrike one of the session's most consequential large-cap winners.

Zscaler, Inc. (ZS) +16.53%
