As Global Markets Tanked Over Iran, U.S. Stocks Were Mostly Unscathed. Here’s Why.

Global markets sold off sharply after renewed conflict with Iran sparked fears of higher oil prices and economic disruption, but U.S. stocks largely shrugged off those losses. U.S. indexes such as the S&P 500 and Nasdaq quickly recovered early declines, helped by gains in energy and tech sectors and historical patterns showing limited long-term impact from geopolitical shocks. The resilience reflects investor confidence that the conflict won’t severely derail the U.S. economy or corporate earnings.
