Most U.S. stocks are rising, but drops for some influential technology companies are keeping the market in check. The S&P 500 was nearly unchanged Wednesday. The Dow Jones Industrial Average added 50 points, and the Nasdaq composite fell 0.4%. General Mills helped lead the market after delivering better results for the latest quarter than analysts expected. Stocks also got a lift after Treasury yields pared gains following a weaker-than-expected report on U.S. manufacturing. That could allow the Federal Reserve to hold off on increases to interest rates this year. But drops for some AI winners restrained the market's gains.
