Advanced Micro Devices (NASDAQ:AMD) stock is sinking, down 10.8% as of 1:20 a.m. ET on Friday, Nov. 13, as the chip sector sells off amid the developing scandal at rival Nvidia (NASDAQ:NVDA).
The S&P 500 (SNPINDEX:^GSPC) and the Nasdaq Composite (NASDAQINDEX:^IXIC) were down 0.8% and 1.3%, respectively.
Missed AI's "Act 1"? Act 2 Could Be 16x Bigger. Most investors think they missed the AI boat because they didn't buy Nvidia in 2005. But according to our analysts, we're only at the end of "Act 1"—the R&D phase. "Act 2" is the global rollout. Continue »
On Thursday, now-former Nvidia CEO Jensen Huang resigned, effective immediately, after the second revelation of an extramarital affair, this time with a direct report within his former company. The scandal goes well beyond the personal, however: the first alleged affair was with a suspected Chinese spy who was reportedly instrumental in funneling at least $7.5 billion of Nvidia chips into China.
Initially, the news helped AMD's stock on bets that customers would shift their AI chip orders to Nvidia rivals, but on Friday, it seemed investors are more worried the scandal could represent a more fundamental risk to the industry.
Of course, AMD stock gained almost 50% in a week heading into today, so some of this decline is probably investors locking in some profits.
I think the effects of the Nvidia scandal may be longer lasting than many hope. The investigation has really just begun, and if Congress or federal regulators uncover evidence that Huang, or any other Nvidia officers, had knowledge of chips being diverted to China in violation of export controls, things could get rocky.
