The U.S. stock market stumbled Tuesday as a once-relentless, tech-driven rally showed signs of fatigue, with investors growing increasingly cautious about the strength of the artificial intelligence boom and the broader economic outlook.
The S&P 500 fell roughly 0.8%, marking its fourth consecutive day of losses. The Dow Jones Industrial Average dropped nearly 500 points, or more than 1%, while the Nasdaq Composite slid 1.2%, extending a multi-day pullback in the market's most heavily weighted technology names.
