Wall Street edges higher as Nvidia drops after CEO resigns

US stocks edged higher on Thursday despite Nvidia shares falling about 4 percent after CEO Jensen Huang resigned, with the 10-year US Treasury yield climbing back above 5 percent. Nvidia named CFO Colette Kress as interim CEO while searching for a permanent successor. Huang's resignation follows reports of an affair with a Chinese businesswoman suspected by US authorities of spying for Beijing, raising questions about the chipmaker's future and the AI boom. Competitors gained, with Advanced Micro Devices up 7 percent and Broadcom rising 5.4 percent, while Chinese tech firms using Nvidia chips fell sharply, including Alibaba down 7.1 percent. The Dow rose 0.40 percent, the S&P 500 gained 0.29 percent, and the Nasdaq added 0.31 percent. The dollar hit a 19-month high on expectations of a December Federal Reserve rate hike, while US crude rose to $86.81 a barrel.
