NVDA shares lower in the after hours based on potential new restriction of chips to China.

Shares of Nvidia Corp. (NVDA) and Advanced Micro Devices Inc. (AMD) slumped in the extended session Tuesday following a report that the Biden administration is considering a new ban of sales of AI chips to China. Late Tuesday, the Wall Street Journal reported the Commerce Department could further block sales of AI chips to China without obtaining a special license first. Nvidia shares fell after a 3.1% rise to close at $418.76, and AMD shares fell 2%, after a 2.7% gain in the regular session to close at $110.39. Both Nvidia and AMD have launched new AI chips this year. The ban would follow upon similar actions last year that threatened $400 million in Nvidia sales, but the company found a workaround in supplying a version of products that avoided the ban. At the close, Nvidia shares were up 187% in 2023, and AMD shares were up 70% for the year.
