Nvidia's Big Week Starts as Micron Drops 6% on China Supply Reports

U.S. stocks were mixed Monday as AI hardware makers fell, with Micron dropping 6% on China supply reports and Nvidia declining 2.1% ahead of its Wednesday earnings. The Dow rose 0.24% while the Nasdaq fell 0.61%. Micron's decline followed weekend reports that the Trump administration might allow Apple to buy memory chips from Chinese suppliers ahead of President Xi Jinping's visit. A Micron researcher also warned that AI computing speed is outpacing memory bandwidth, creating an industry-wide bottleneck. Alphabet rose 1.7% as AI hardware buyers outperformed makers. Nvidia's earnings Wednesday is seen as a key test of AI sentiment, with the Fed's inflation gauge and Jackson Hole symposium also scheduled this week. The Iran war, now six months old, prompted Treasury sanctions that contributed to falling oil prices.
