A major tech selloff stretched into a second day Tuesday as investors questioned whether artificial intelligence will generate the profits that have fueled lofty valuations for companies such as Alphabet, SpaceX and Nvidia.

Around noon ET, the tech-heavy Nasdaq Composite was down 409 points, or 1.6%, to 25,758. The decline marks a second day of losses, with the Nasdaq closing 1.3% lower on Monday.

The S&P 500 tumbled 1%, while the Dow Jones Industrial Average rose 43 points, or 0.1%, to 51,756.

For months, Wall Street has embraced tech stocks, helping drive the market to record highs on optimism that companies pouring billions into AI would translate those investments into faster revenue growth and higher profits. Investors are now demanding more evidence that the spending will pay off.

On Tuesday, several of the stocks that have powered the market's rally came under pressure as skepticism grew.

"For a long time, the market treated AI spending as unquestionably positive," Nigel Green, CEO of the financial consultancy deVere Group, said in an email Tuesday. "Investors are now becoming more demanding. They want evidence that unprecedented spending will translate into unprecedented profits."
