Nasdaq jumps more than 2.5% as AI-led tech rally lifts S&P 500 about 1% and Dow 0.7%

U.S. stocks finished the week higher, with the Nasdaq Composite up more than 2.5%, the S&P 500 rising about 1%, and the Dow Jones Industrial Average gaining 0.7%. The advance was led by AI-linked technology strength, with semiconductor and broader tech shares standing out. Easing Middle East tensions and a pullback in oil prices also helped, while the Federal Reserve holding rates steady and a stronger dollar underscored ongoing policy constraints. The move was described as an event-driven, technical rebound rather than one tied to specific earnings or a policy shock.
