Wall Street mixed as Apple tumbles to two-year low

The S&P 500 and Dow Jones swerved between gains and losses before ending virtually flat. Up 0.90 percent, Microsoft was the largest upward force in the S&P 500. Apple Inc , a mainstay in many portfolios, was the heaviest drag on the three major indexes, slumping 2.35 percent to $90.34, its lowest since June 2014, as worries festered about slowing demand for iPhones.
