Stocks edged up at the open on Wednesday after better-than-expected New York Fed manufacturing data and remarks that reiterated China's commitment to investing in euro zone debt.

The Dow Jones industrial average <.DJI> edged up 19.29 points, or 0.15 percent, at 12,897.57. The S&P 500 Index <.SPX> added 3.96 points, or 0.29 percent, at 1,354.46. The Nasdaq Composite <.IXIC> rose 12.31 points, or 0.42 percent, at 2,944.14.

Gains were capped after a separate report showed U.S. industrial production was unexpectedly flat in January.
