S&P 500 rises 0.4% as investors weigh US midterm elections and semiconductor gains

The S&P 500 rose 0.4% and the Nasdaq Composite climbed 0.8% on Tuesday, while the Dow Jones fell 0.4% as markets monitored US midterm election results. Prediction markets pointed to an over 75% probability of a Democratic sweep of Congress. Technology gains supported equities, with Advanced Micro Devices rising 3.7% and Broadcom adding 3.1%, offsetting a 1.9% drop in Apple. The moves followed recent market turbulence that saw the Nasdaq 100 slide 10% into correction territory. Meanwhile, fixed-income yields climbed, with the 10-year Treasury yield advancing 5 basis points to 4.96%.
