The billionaire investor says US stocks are in a “very similar” position as in the lead-up to the internet bubble bust at the turn of the millennium.

Global technology stocks regained some ground on Tuesday a day after a low-cost Chinese AI model rattled markets, while traders rotated back into the dollar from safe-haven currencies.

The S&P 500 was down 1.6% in morning trading. Big Tech stocks took some of the heaviest losses, with Nvidia down 11.2%, and they dragged the Nasdaq composite down 2.7%.

The selloff could provide traders an attractive entry opportunity in higher-beta altcoins such as Solana's SOL, which endured a double-digit pullback, one analyst said.

Nvidia, which designs chips used in AI applications, clawed back gains of 8.9% on Tuesday, leaving it well below last week’s levels. All three major indices on Wall Street finished higher, with the Nasdaq Composite rising 2.
