U.S. stocks opened lower Tuesday, slumping after disappointing results from Snapchat parent Snap Inc. sent tech-related shares skidding. The fall comes after stocks bounced sharply higher on Monday following a rout that took the S&P 500 to the brink of a bear market on Friday. The Dow Jones Industrial Average was down 150 points, or 0.5%, while the S&P 500 slumped 1% to 3,933. The Nasdaq Composite dropped 1.6% to 11,346. Snap shares were down 37%.
