New York – Major U. S. stock indices experienced a sharp decline on Tuesday, with the Nasdaq and S&P 500 closing at over one-week lows. The downturn was largely attributed to a significant sell-off in semiconductor stocks, as investors grappled with concerns over a potentially more hawkish stance from the Federal Reserve and the escalating costs associated with artificial intelligence (AI) development.
The technology sector bore the brunt of the market's pessimism. Chipmakers such as Intel, Marvell Technology, and Advanced Micro Devices saw significant drops, with losses ranging between 6.2% and 8.7%. Memory chip manufacturers Micron Technology and SanDisk, which had been strong performers earlier in the year, experienced steep declines of 12% and 13%, respectively. The Philadelphia SE Semiconductor index tumbled by 7.3%, underscoring the broad weakness within the sector.
Investor sentiment was further shaken by doubts surrounding the sustainability of debt-funded AI spending by major tech companies, despite their extended valuations. Analysts pointed to the highly concentrated nature of the "AI trade" as a vulnerability, suggesting that even minor shifts in sentiment could trigger rapid unwinding. The upcoming earnings report from Micron Technology was anticipated to provide further insight into the health of the memory and AI chip market.
Adding to the market's unease were signals from the Federal Reserve regarding inflation and potential interest rate adjustments. Recent projections indicate that a majority of Federal Reserve officials now anticipate a rate hike by the end of 2026, a shift from previous expectations. This growing prospect of tighter monetary policy, coupled with scrutiny over AI spending, contributed to a risk-off sentiment across Wall Street, leading investors to seek opportunities in other market segments.
