U.S. stocks bounced back strongly in a choppy trading Tuesday after Federal Reserve Chairman Ben Bernanke defended for the central bank\'s massive bond purchasing in testimony before Congress. The Dow Jones Industrial Average climbed 115.96 points, or 0.84 percent, to 13,900.13. The Standard & Poor\'s 500-stock Index surged 9.09 points, or 0.61 percent, to 1,496.94. The Nasdaq Composite Index rose 13.40 points, or 0.43 percent, to 3,129.65. Wall Street moved higher after Bernanke said Tuesday in testimony before the Senate Banking Committee that Fed intended to keep its stimulus policies going until hiring improves significantly, giving no hint of whether the central bank may curtail the so-called quantitative easing before the end of this year. Investors\' mood also was bolstered by Bernanke\'s \"not seeing much evidence of equity bubble\", in the testimony.
