Some key earnings, more testimony from Federal Reserve Chair Janet Yellen and economic data: that's what to watch on Wall Street for Wednesday, Feb. 25. Retail giant Target Corporation (TGT) will report financial results before the opening bell. Analysts are looking for earnings per share of $1.46 on sales of $21.6 billion. Also, before the opening bell, Campbell Soup Co. (CPB) reports, along with Starz (STRZA) and Dollar Tree (DLTR). Plus, Federal Reserve Chair Janet Yellen will address the House Financial Services Committee at 10am Eastern. This comes after delivering testimony in front of the Senate Banking Committee on Tuesday, where Yellen maintained the central bank's vague language when it comes to when short term-interest rates will be raised. TheStreet's Scott Gamm has details from New York.
