A sell-off in mega-cap stocks sparked a broader slump across Wall Street on Friday, though the three main benchmarks managed to hold on for weekly wins. Today's price action puts the Santa Claus rally at risk, which has historically spelled trouble for January returns.
At the close, the Dow Jones Industrial Average was down 0.8% at 42,992, the S&P 500 was off 1.1% at 5,970, and the Nasdaq Composite had lost 1.5% to 19,722.
