Index closes

The S&P 500 closed at 7,354, down 4.36%. The Nasdaq 100 fell 6.36% to 26,630. The Dow Jones ended at 51,523, down 3.44%, and the Russell 2000 lost 4.45% to 2,730.

Macro & after the close

Stocks fell sharply in a broad-based selloff driven by investor fears about the unwinding of the year's most popular AI trades.

After the midterms, investors positioned for a slower data center build-out, undermining shares of chipmakers and data-center suppliers. Chip and data center stocks fell for a second day after the Democrats won Congress, including in states where voters pushed back on data centers.

The selloff fueled a flight-to-quality trade in Treasurys, with the yield on the 10-year note falling to its lowest level since Sept. 9.
