The S&P 500 and Dow Jones were up more than 1 percent while the Nasdaq rose more than 2 percent, boosted by better-than-expected results from several major tech companies.

At 1:55 p.m., the Dow Jones industrial average rose 187.14 points, or 1.14 percent, to 16,586.81, the S&P 500 gained 31.81 points, or 1.67 percent, to 1,935.82 and the Nasdaq Composite added 87.12 points, or 2.02 percent, to 4,403.19.
