Dow Plummets Over 800 Points As Big Tech Drives Decline In U.S. Stocks

U.S. stocks nosedived, dragged down by tech, in a wild day of trading Thursday, slamming the brakes on a record-shattering run that had lifted Wall Street to new heights. The Standard& Poor's 500- stock index shed 125.78 points, a 3.5 percent slide, to end at 3,455.06. Apple, the most highly valued publicly traded company in the United States, shed more than 6 percent.
