JiJie.com news: U.S. stocks closed mixed on Monday. The Dow Jones Industrial Average rose, the S&P 500 was nearly flat, and the Nasdaq Composite fell slightly. The major indexes showed clear rotation. The Dow and the Russell 2000 logged solid gains, while large-cap technology stocks pulled back. Semiconductor and artificial intelligence-related shares were the biggest losers on Monday. After strong performance, investors took profits and shifted to some lower P/E blue-chip stocks and smaller-cap stocks. Broad selling was seen across the board, including AI chip designers, semiconductor equipment makers, optical networking, and storage-related companies. With several major technology firms set to release earnings this week, investors appear to be reducing risk ahead of the reports—raising the bar for companies to not only deliver strong earnings but also provide optimistic guidance to justify elevated valuations. The next few trading days may determine whether Monday’s weakness reflects healthy profit-taking or signals a deeper rotation out of the AI and semiconductor sectors.
