NEW YORK (Reuters) - U.S. stocks were set to bounce at the open on Wednesday, on the heels of the biggest drop in the S&P 500 since mid-April, as earnings season winds down and ahead of congressional testimony from Federal Reserve Chair Janet Yellen.
Developments in Ukraine helped sentiment, as Russian President Vladimir Putin said Wednesday he was ready to discuss a way out of the crisis with the head of the Organization for Security and Co-operation in Europe (OSCE).
Testimony from Fed Chair Yellen to the Joint Economic Committee, scheduled for 10:00 a.m. (1400 GMT), will be closely monitored. While Yellen is largely expected to maintain a dovish policy stance, investors will look for clues on how soon interest rates will be raised, with many expecting hikes beginning in 2015.
