Apple drags down Wall Street

Apple weighed on the three major U.S. stock indexes on Thursday morning, a day after the tech giant unveiled the new iPhone 7 that failed to impress Wall Street. Shares of Apple fell 2.1 percent, their steepest decline since June 24 when the markets witnessed a broad selloff after the result of the Brexit vote. Investor reaction to an unexpected drop in weekly jobless claims and the European Central Bank's decision was largely muted.
