Takeaway

The defensive rotation that held the Dow up most of Friday gave way at the close. The Dow reversed into the red, the S&P 500 lost more than 1%, and the Nasdaq finished down about 2%, capping a volatile week. Meta was the weakest Mag7 name going into its Oct. 21 report, so next week's earnings start against a tape that is selling AI exposure first.

What happened

4:04 p.m. ET, Yahoo Finance close: The Dow slipped 0.4%, the S&P 500 lost 1.1% and the Nasdaq Composite fell 2.1%. Yahoo's quote strip at the close showed META -3.72%, TSLA -2.13% and CoreWeave -11.91%.
The reversal: The Dow was up about 0.4–0.6% in the morning (Yahoo Finance live blog, ~9:53 a.m. ET) as money rotated into financials, healthcare and payments names. That support had faded by the close.
3:00 p.m. ET, Bloomberg: The Nasdaq 100 was down 2.5% and oil was climbing. Chipmakers were on track for an eighth straight daily loss, a streak not seen since 2008. CoreWeave, whose bonds recently traded at levels that typically signal distress, sank about 14%.
Beyond the Mag7: Yahoo reported Palantir down about 7%, heading toward correction territory, which shows the selling had spread past the chips into AI software names.
Tesla gave back its Roadster pop: It was up about 3% before the open on the Roadster reveal and closed down about 2%.

Mag7 impact

META — bearish going into the print. It was the worst Mag7 performer at the close, down about 3.7% heading into Oct. 21. The market is pricing capex risk ahead of the report, so guidance on AI spending and returns decides whether this is a setup or a warning.
TSLA — mixed. The Roadster halo lasted one session. Its Oct. 21 earnings now carry more weight than the product event.
NVDA — bearish. The chip losing streak and CoreWeave's distressed bonds keep the financing story behind its demand under pressure.
MSFT, GOOGL, AMZN — bearish by association. These are hyperscalers in an index that fell 2% with no single-name catalyst. That is positioning, not news, which cuts both ways.
AAPL — relative haven, unconfirmed. It was firm in the morning on iPhone Duo demand. Without a close-level print in the sources, its finish is not confirmed here.

What to watch next

Weekend credit: CoreWeave bond and CDS levels heading into Monday's open.
The chip streak: whether semis extend it on Monday or bounce.
Oct. 21 double header: META and TSLA earnings. META's capex guidance is the main test for the AI trade.
Oct. 28 FOMC: hike pricing after the hot CPI and PPI prints, plus oil's climb as an extra inflation input.
