NEW YORK (AP) — U.S. stocks extended their push to record heights on Wall Street Thursday, led by big gains for chipmakers.

The S&P 500 rose 16.91 points, or 0.3%, to 5,241.53 and set an all-time high for a third straight day. Three out of every four stocks in the index gained ground.

The Dow Jones Industrial Average gained 269.24, or 0.7%, to 39,781.37, and the Nasdaq composite rose 32.43, of 0.2%, to 16,401.84. Both indexes added to records set a day earlier.

Micron surged 14.1% and led chipmakers higher after reporting much stronger results for its latest quarter than expected. It also gave a forecast for profit in the current quarter that topped analysts’ estimates, as it benefits from a rush into artificial intelligence.
