Nvidia board weighs CEO ouster; Alibaba falls on chip fears

U.S. stock futures pointed mostly lower Thursday, led by a 0.9% drop in Nasdaq futures, after reports that Nvidia's board may oust CEO Jensen Huang and as Alibaba shares slumped on U.S. chip export concerns. Nvidia shares fell over 6% in after-hours trading following a Wall Street Journal report that the board is preparing to remove Huang over two extramarital affairs, including one with an alleged Chinese spy. Analysts predicted the company could lose a quarter of its valuation if he departs. Alibaba tumbled more than 6% in Hong Kong on fears the scandal could intensify U.S. scrutiny of chip access for Chinese firms. Oil prices remained volatile amid mixed signals on potential U.S.-Iran talks to end the war.
