NEW YORK: Wall Street ended mixed on Thursday, as Nvidia and other technology stocks dipped, while defence companies advanced after President Donald Trump called for an enlarged US$1.5 trillion military budget.
Nvidia slid 2.2%, Broadcom declined 3.2% and Microsoft dipped 1.1%. The S&P 500 technology index lost 1.5%, leaving it down about 1% so far in 2026, as investors grew more finicky about AI-related stocks whose valuations have been inflated by outsized gains in recent years.
Alphabet gained 1.1% the day after the Google parent surpassed Apple in market capitalization for the first time since 2019, becoming the second-most valuable U.S. company. The iPhone maker was down 0.5%.
"While AI is still hot, there are going to be winners and losers," said Art Hogan, chief market strategist at B. Riley Wealth. "It's become a 'show me' sector. Show me how you monetize this. Show me if there's going to be a return on the capex you're putting into your development."
Defense stocks gained after Trump said the 2027 US military budget should be US$1.5 trillion, much higher than the US$901 billion approved by Congress for 2026.
Lockheed Martin rose 4.3%, Northrop Grumman added 2.4% and Kratos Defense jumped 13.8%.
Some defence stocks fell in the prior session, after Trump threatened to block defence contractors from paying dividends or buying back shares until they speed up weapons production.
