WATCH: The Nasdaq notched a record high close, lifted by Micron Technology and other AI-related stocks, while the S&P 500 ended flat and the Dow closed lower. Lisa Bernhard reports

What happened

The Nasdaq closed at a record high, helped by Micron Technology and other artificial-intelligence-related stocks. The S&P 500 finished flat, and the Dow closed lower.

Confirmed

Global impact / market context

This shows investors are rewarding companies tied to artificial intelligence, which means computer systems that learn from data. Money flowing into those stocks can lift the Nasdaq while leaving broader indexes like the S&P 500 and Dow behind.

Analyst inference

A record Nasdaq close next to a flat S&P 500 and a lower Dow means gains were concentrated in technology and AI-linked shares rather than spread across the market. That concentration can make overall market performance depend heavily on a small group of stocks.

Analyst inference

What to watch

1. Watch whether Micron Technology and other artificial-intelligence-related stocks keep leading the Nasdaq after this record high close, since the article names them as the drivers. Confirmed
2. Watch whether the S&P 500 and Dow catch up to the Nasdaq or keep lagging, because that split shows if gains stay narrow or broaden across more companies. Analyst inference
3. Investors could track upcoming company earnings and capital spending plans, which means money businesses budget for long-term projects, to see if AI demand keeps supporting these stocks. Proposed
