“Nasdaq tumbles 2%, heads for worst week since June as investors rotate out of AI trade and oil rises: Live updates”

What actually happened

The Nasdaq Composite fell on a Friday that capped a losing week, as money moved out of AI-linked names (chipmakers, neoclouds) and into other sectors, while crude oil jumped on Iran-related Strait of Hormuz tensions and Ukrainian strikes on Russian refineries. The Dow held up better, cushioned by energy stocks like Chevron.

Key facts

• Nasdaq Composite: the Nasdaq Composite shed 2.2%, rounded to "2%" in the headline.
• S&P 500 and Dow: the S&P 500 traded down 1.2%, while the Dow Jones Industrial Average outperformed as it fell 268 points, or 0.5%.
• Weekly Nasdaq performance: the Nasdaq has shed more than 4%. The tech-heavy index was on track for its worst weekly performance since June, directly matching the headline's claim.
• AI-trade rotation evidence: the SMH is down 8% week to date, on pace for its biggest weekly decline since July, and shares of neoclouds like CoreWeave, which has seen its total debt rise to more than $51 billion, were down 10%, putting the stock's week-to-date losses at more than 23%.
• Oil move: West Texas Intermediate crude futures increased 2% to above $100 per barrel, while Brent crude futures advanced 3% to above $109, tied to rising tensions between the U.S. and Iran as well as between Russian and Ukraine.
• Breadth nuance not in the headline: the S&P 500 was more evenly split despite the losses at the index level, with about 280 losers in the index and 222 gainers.

What to watch for

Watch whether the AI-debt concern (CoreWeave's $51 billion load) becomes the dominant market story next week or fades once oil tensions ease. Also watch the Oct 27-28 Fed meeting: the article notes an 85% market-implied chance of a hold, which could reverse quickly if the hot PPI/CPI prints persist.
