Apple, Boeing drag down Wall Street

Apple and Boeing's disappointing forecasts dragged down U.S. stock indexes on Wednesday, as anxious investors awaited the Federal Reserve's statement on monetary policy. Apple's shares were down 5.3 percent at $94.67 after the company also reported its slowest-ever rise in iPhone shipments on Tuesday. The stock was the biggest drag on the S&P 500 and the Nasdaq, and was set for its biggest fall since August.
