Most U.S. stocks rose, and the Dow Jones Industrial Average set another record, but more drops for chip stocks and other AI winners kept indexes mixed. The S&P 500 finished basically unchanged on Thursday, even though seven out of every 10 stocks within the index rose. The Dow rallied 1.1%, while the Nasdaq composite dropped 0.8% after erasing an early gain. Stocks broadly got help from data showing U.S. hiring slowed last month. That pushed traders to trim bets for a possible hike to interest rates later this month. But chip stocks from Seoul to New York continued to slide.
