Wall Street edges up, Nvidia drops after CEO resigns

US stocks turned slightly bullish on Thursday, despite Nvidia shares dropping after CEO Jensen Huang's resignation. The 10-year US Treasury yield surged above 5 percent. Nvidia CEO Jensen Huang had reportedly been involved in an affair with a Chinese businesswoman suspected of spying for Beijing. Huang's resignation has raised concerns about the company's future and the AI boom.

In response, Nvidia's CFO, Colette Kress, will serve as interim CEO as the company searches for a permanent successor. Huang's departure has also impacted competitors - Advanced Micro Devices shares rose 7 percent, while Broadcom climbed 5.4 percent. Intel remained flat. Chinese tech firms that utilize Nvidia chips for their AI models saw significant declines, with Alibaba down 7.1 percent and Tencent falling 2.6 percent.

The three major US stock indexes saw slight gains, while a world stocks index remained flat. Investors remain uncertain about the implications of Huang's resignation and the potential impact on Nvidia's stock price.
