Wall St rises as Yellen hints at "gradual" rate hikes

Wall Street was higher on Wednesday, led by financial stocks, after Federal Reserve Chair Janet Yellen said conditions in the United States would allow the Fed to pursue "gradual" adjustments to monetary policy. Goldman Sachs, up 1.3 percent, gave the biggest boost to the Dow. Yellen is scheduled for an appearance before the House Committee on Financial Services at 10:00 a.m. ET (1500 GMT).
