Nvidia and other AI chip stocks regained lost ground Tuesday after the ugly sell-off sparked by news related to China's DeepSeek.

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.

That bounce comes after stock plunged 17% on Monday and slashed more than $595 billion from the company's valuation, the biggest single-day market cap decline on record. But retail investors bought the dip at a record level, even as the sell-off gripped Wall Street, according to Vanda Research.
