The S&P and Nasdaq indexes slipped on Wednesday in choppy trading as tech shares tumbled after Intel Corp said uncertainty ruled out a clear revenue forecast, underscoring worries about a lack of corporate visibility ahead.

But the Dow Jones industrial average held in positive territory helped by gains in Procter & Gamble
after the company raised its dividend.

The Nasdaq was the worst performer of the indexes as Intel dropped more than 4 percent after the top global chipmaker was unable to provide a clear revenue forecast for the second quarter.

The Dow Jones industrial average <.DJI> edged up 8.76 points, or 0.11 percent, at 7,928.94. The Standard & Poor's 500 Index <.SPX> was off 1.34 points, or 0.16 percent, to 840.16. The Nasdaq Composite Index <.IXIC> gave up 20.45 points, or 1.26 percent, at 1,605.27.
