In a turbulent session, major U.S. stock indexes ended lower as rising crude oil prices reignited inflation concerns, prompting a selloff in technology stocks. The S&P 500 and Nasdaq experienced declines, with worries escalating over elevated Treasury yields and geopolitical tensions, including fears of renewed military actions in the Middle East. The Dow Jones managed to climb earlier in the day but ultimately succumbed to the overall market pullback. Analysts are watching the impact of growing AI revenue concerns and the recent volatility in semiconductor stocks, further complicating the market outlook as oil prices spike following a fresh tanker attack. Investors remain cautious, keeping a close eye on upcoming economic indicators and Federal Reserve signals.
