- The S&P 500 was little changed as chip stocks slid in a sell-off ahead of Micron's earnings report, according to CNBC's live updates.
- The Dow rose while the S&P 500 and Nasdaq slipped as oil prices tumbled and AI jitters returned to the market, per Yahoo Finance's market wrap.
- Semiconductor stocks resumed their sell-off ahead of Micron's earnings, framing chips as the session's clear laggard versus the Dow's gain.
Why it matters: Micron's earnings are a key bellwether for the semiconductor sector, which carries outsized weight in the S&P 500 and Nasdaq. A pre-earnings sell-off in chips signals investors are hedging into the print, while the divergence between the rising Dow and slipping tech gauges points to rotation away from the AI trade that has driven recent record highs.
