S&P 500 rises 1% as AI stocks surge, oil slides, yields retreat
Wall Street rallied Monday as investors returned to artificial intelligence stocks and oil prices fell sharply. The S&P 500 climbed one-point-five percent, the Nasdaq hit a record close, gaining two-point-three percent. Semiconductor stocks led the advance with Intel jumping twelve percent, AMD surging ten percent and hitting one-trillion dollars in market value for the first time. Meta jumped nearly twelve percent after investors responded positively to its new Muse AI assistant. The rally was also fueled by a sharp drop in crude oil and a retreat in Treasury yields. Oil fell four-point-five percent to below ninety-six dollars a barrel amid hopes for diplomatic progress in the Middle East. The ten-year Treasury yield slipped below five percent. The moves provided relief after a volatile week marked by concerns about AI spending and elevated borrowing costs. The broader market recovery came as traders shook off recent warnings from AI industry leaders about the need for a slowdown.
