NEW YORK (Reuters) - U.S. stocks opened little changed on Wednesday as corporate earnings provided investors with little reason to buy in a stock market that has been unable to find its footing after a strong rally last year.
Shares of IBM weighed down the Dow after the world's biggest technology services company missed revenue expectations for a fourth straight quarter amid weakening demand, particularly in growth markets like China.
The Dow Jones industrial average fell 21.7 points or 0.13 percent, to 16,392.74, the S&P 500 gained 1.57 points or 0.09 percent, to 1,845.37 and the Nasdaq Composite added 8.714 points or 0.21 percent, to 4,234.474.
