Nvidia Results Loom as Tech Stocks Bounce Back for Wall Street

Wall Street's main indexes closed higher on Tuesday as technology stocks recovered from a selloff ahead of Nvidia's results.

The gains came despite ongoing concerns about stretched valuations and the sustainability of the AI boom, which has driven many tech stocks to new highs.

Nvidia's NVDA.O results on Wednesday will be the next test for the earnings-driven rally. If signs of slowing growth emerge, it could reignite worries about how long the AI boom can sustain itself.

Some analysts remain optimistic about the outlook for the US economy and markets, with Joe Quinlan, head of market strategy at Merrill and Bank of America Private Bank, saying 'There's a lot of push and pull, in the bond market, geopolitics, oil.'
