Cybersecurity stocks reportedly lead S&P 500 gains as chip shares fall on September 14

WOLF Financial’s September 14, 2026, market recap named CrowdStrike, Palo Alto and Fortinet as the S&P 500’s three biggest gainers—all cybersecurity stocks.

The account reported semiconductor declines including Teradyne at 13.3%, Lam Research at 8.3%, Intel at 5.6%, Micron at 5.3% and Nvidia at 3.4%. It also listed gains of 3.2% for Google and 2.7% for Meta.

WOLF Financial said the chip selloff followed calls from three AI CEOs over the weekend to slow development.
