Apple drags Wall Street lower ahead of Fed decision

Wall Street was dragged lower on Wednesday, ahead of a policy decision by the U.S. Federal Reserve, after Apple's first revenue decline in over a decade aroused worries about the health of corporate earnings. Apple's shares were down 7 percent at $96.93 and were set for their biggest one-day fall in more than two years. No change in rates is expected but the Fed may signal its intention to tighten policy this year.
