The S&P 500 and Nasdaq powered to fresh records after the Federal Reserve cut interest rates, extending a buoyant post-election rally.
While the Dow finished essentially flat, both the S&P 500 and Nasdaq jumped to new all-time highs, with large tech companies like Facebook parent Meta and Apple surging.
The tech-rich Nasdaq Composite Index led the indices, climbing 1.5 percent to 19,269.46.
The broad-based S&P 500 gained 0.7 percent to 5,973.10, while the Dow Jones Industrial Average was unchanged at 43,729.34.
The US Federal Reserve shrugged off political uncertainty in Washington and moved ahead with a quarter-point rate cut on Thursday, easing monetary policy further as inflation continues to cool.
