Asian stocks wobbled at the start of regional trading on Thursday, while Nvidia shares plunged in after-hours trading on news that its board may oust longtime chief executive Jensen Huang. In Hong Kong, the benchmark Hang Seng Index opened down 194 points, or 0.8 percent, at 24,121. The tech index fell 32 points, or 0.8 percent, to 3,995 while the China Enterprises Index slipped 66 points, or 0.81 percent, to 8,105. On the mainland, the Shanghai Composite Index inched down seven points, or 0.21 percent, to open at 3,673. The Shenzhen Component Index was 28 points, or 0.25 percent, lower at 11,361 while the ChiNext Index was down 0.5 percent at 2,559. Nvidia's board is meeting late on Wednesday to decide whether to oust Huang, a source said, as the world's dominant supplier of AI processors grapples with the fallout of allegations that he had an affair with a suspected spy for China. The New York Times has also reported that Huang had had an affair with a company executive who reported to him. "It looks bad from every single angle," said Jake Dollarhide, chief executive at Longbow Asset Management in Tulsa, Oklahoma. "I believe the board won't oust him until they have an all-star, a known entity in the tech sector, to replace him. At the end of the day, let's not forget that the Nvidia chip is the centrepiece of the AI story." Shares in Nvidia slid more than eight percent after the bell, weighing on S&P 500 e-mini futures, which slipped 0.4 percent. In Tokyo, the Nikkei opened 226 points, or 0.37 percent, higher at 61,475 and was 390 points higher still at one stage before noon. In Seoul, the Kospi opened 10 points, or 0.2 percent, at 5,385 and, like the Nikkei, tracked up cautiously by 38 points at one stage before lunch. "Renewed optimism around AI drove US equities higher overnight, with positive developments around CoreWeave and Anthropic adding to enthusiasm around the sector and helping the S&P 500 and Nasdaq rally," Westpac analysts wrote in a note.
