Stocks drop amid tech sell-off

The S&P 500 closed down 3.51%, while the Nasdaq was off 4.98% (598 points) and the Dow fell 2.78% (808 points) on Thursday. Stocks had their worst day since June.

The big picture: The indices are still hovering near their highest levels ever — the S&P 500 is still higher than it was at any time before the pandemic — but the pullback is being led by a drop in the technology stocks that led the advance to record highs.
