U.S. stocks jumped for a second day as fears around a crisis in China's property market eased somewhat and as the Federal Reserve kept current monetary stimulus in place for just a little bit longer.

The Dow Jones Industrial Average gained 506.50 points, or 1.48%, to 34,764.82, with steady buying throughout the trading day. Thursday's rally adds to a 338-point gain in the prior session. The S&P 500 rose 1.21% to 4,448.98 and the Nasdaq Composite added 1.04% to 15,052.24.
