US stocks erase a morning rally as tech stocks swing following last week's sell-off

NEW YORK (AP) — After rallying in the morning, the U.S. stock market weakened through the day on Monday and then turned lower as the tech and AI industries remain shaky following their sell-off last week.

The S&P 500 dropped 0.3% after rising as much as 1.1% during the morning. The Dow Jones Industrial Average was up 288 points, or 0.6%, as of 2:50 p.m. Eastern time, while the Nasdaq composite was down 0.8%.
