Wall Street opens little changed; Yellen in focus

U.S. stocks opened little changed on Monday as investors awaited a speech by Federal Reserve Chair Janet Yellen, less than a week after the Fed raised interest rates for only the second time since the financial crisis. Yellen will be speaking on "the State of the Job Market" at 1:30 p.m. ET (1830 GMT) at the University of Baltimore. U.S. stocks fell on Friday, weighed by a more than 4 percent drop in Oracle shares and news that a Chinese Navy warship seized a U.S. underwater drone.
