Nvidia shares' 9% recovery Tuesday was the second-best day in terms of market cap added for any company ever, trailing only a record it set in July.

U.S. stocks recovered some ground Tuesday morning after getting hammered by fears over China's DeepSeek AI model built on a shoestring budget.

Nvidia staged a moderate rebound on Tuesday, rising as much as 3%, following a 17% drop the prior day. More broadly, major US indexes rallied after the S&P 500 and Nasdaq 100 saw sharp losses on Monday amid concerns over the Chinese AI firm DeepSeek's rapid and seemingly cost-effective advances.
