Wall Street slides on AI weakness
The Guardian reported that AI-related stocks pulled US markets lower on Thursday. The S&P 500 fell 1.2% to 7,663.43 for its worst day since July, while the Nasdaq composite tumbled 2.6% to 26,008.86. The Dow Jones Industrial Average added 11.89 points to 52,867.98. Despite the tech-led decline, two out of every three stocks in the S&P 500 rose.
Lam Research fell 11.8% even after reporting summer profit and revenue slightly above analyst expectations. Meta Platforms lost 7% after stronger-than-expected revenue but weaker profit, and Tesla fell 3.1%. Nvidia dropped 4.4% and CoreWeave fell 10.1%. The Guardian attributed the pressure to worries about borrowing costs for datacenters and AI chips and to valuations after a years-long rally.
Oil and bonds react to war uncertainty

In bond markets, the 10-year Treasury yield fell to 4.97% from 5.13% late Wednesday as investors bought US government debt for safety.
