One day after its best session in months, Wall Street gave it all back and more.
A brutal sell-off led by stocks tied to AI data centers swept the market Thursday. The Associated Press reported it was the S&P 500's worst day since the April 2025 "Liberation Day" tariff shock [1].
The Dow fell 1,833.06 points, or 3.44%, to 51,523.06. The S&P 500 dropped 4.36% to 7,353.73, and the Nasdaq composite lost 5.52% to 24,315.00 [2].
All 11 sectors of the S&P 500 finished in the red. Technology fell 7.30% and industrials 4.12%; even consumer staples slipped 0.67% [3].
The Nasdaq closed nearly 12% below its Oct. 6 record, past the 10% line that marks a correction. Reuters said the selling was driven by worries that Democratic wins, including in Texas, would slow the AI data-center build-out [4].
Ray's take: when a few giant stocks carry a market all year, they can drag it down just as fast. Know what you own.
