1. What Happened Today
U.S. stock markets experienced modest gains, with the S&P 500 rising 0.25% and the Dow Jones climbing 100 points, as investors displayed cautious optimism amid ongoing geopolitical tensions, particularly in Iran. Oil prices surged past $103 per barrel, driven by escalating attacks on energy infrastructure in the region, which raised concerns about supply disruptions. Notable movers included Micron Technology (MU), which advanced 4.44% ahead of its earnings report, and Nvidia (NVDA), which saw fluctuations due to new U.S. export controls on semiconductors. The tech sector remained a focal point, with AI-driven stocks like Oracle and CoreWeave garnering attention for their growth potential despite broader market uncertainties.
