Nvidia's Big Week Starts With Mixed Markets as Micron Drops 6%
U.S. stock markets were mixed on Monday as AI hardware makers fell while buyers of the technology rose, ahead of Nvidia's earnings report. The Dow Jones Industrial Average gained 0.24%, while the S&P 500 slipped 0.33% and the Nasdaq Composite dropped 0.61%. Micron Technology fell 6% after reports suggested the Trump administration might allow Apple to buy memory chips from Chinese suppliers, and a Micron researcher warned that AI computing speed is outpacing memory bandwidth.

The ongoing Iran war and Treasury Secretary Scott Bessent's new sanctions push also loom over markets.
