The Nasdaq briefly turned negative on Friday as a sell-off in the shares of chipmakers and other technology bellwethers, including Apple Inc , derailed an earlier advance.

The pressure from tech also caused both the Dow and the S&P 500 to pare some of their initial gains.

Tech has been one of the hard-charging sectors in the market's run-up from the 12-year lows of early March, and profit-taking has been anticipated for some time.

The Dow Jones industrial average <.DJI> was up 51.30 points, or 0.61 percent, at 8,461.15. The Standard & Poor's 500 Index <.SPX> was up 6.29 points, or 0.69 percent, at 913.68. The Nasdaq Composite Index <.IXIC> was down 3.57 points, or 0.21 percent, at 1,712.67.

After the market open the Nasdaq had risen more than 1 percent.
