Wall Street ended sharply lower on Tuesday, driven by a relentless selloff in semiconductor stocks that has now extended into a second day. The Nasdaq tumbled more than 2% in opening trade as the tech rout deepened, with both the S&P 500 and the Dow also closing in negative territory.
The wave of selling was fueled by mounting unease over the sustainability of massive AI-related capital expenditures. Major tech companies have poured billions into AI infrastructure, but investors are now questioning whether those investments will deliver sufficient returns, triggering a broad reassessment of the sector's valuation.
The semiconductor selloff was the clearest signal of the shift—it hit industry bellwethers hard, with Nvidia among the most visible decliners. Asian markets were also set to extend the losses, signaling that the AI-chip fueled rout is not confined to U.S. exchanges.
Market participants are now watching closely for further moves, as the cooling AI trade could ripple across sectors reliant on tech spending. The selloff also weighed on retail and other consumer-facing names, though not all stocks fell—some companies like Walmart and Wendy's remained in focus for diverging performance.
Some analysts argue the pullback is a healthy correction after an extended run, not the start of a prolonged downturn. They point to strong underlying demand for AI services and note that valuations had become stretched, making a reset overdue.
