The S&P 500 and NASDAQ Composite Record New All-time Highs - Tekedia

U.S. stock benchmarks hit fresh record highs, with the S&P 500 at 7,563 and the Nasdaq Composite at 26,917.

The rally was driven mainly by mega-cap tech and semiconductor stocks linked to AI spending.

Support also came from passive inflows, corporate buybacks, lower real yields, and momentum buying.

The move highlights how market gains are increasingly concentrated in a narrow group of AI leaders.
