Wall Street falls as Apple hits two-year low

Wall Street lost its early gains on Thursday to turn negative in late morning trading after Apple fell to an almost two-year low. "This week there is a lack of big macro news, so the market is hunting around for something to latch on to," said John Canally, investment strategist and economist for LPL Financial in Boston. The Nasdaq Composite was down 25.82 points, or 0.54 percent, at 4,734.87.
