Wall Street edges up at open on data, China

US 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 Eurozone debt.

The Dow Jones Industrial Average edged up 19.29 points, or 0.15%, at 12,897.57. The S&P 500 Index added 3.96 points, or 0.29%, at 1,354.46. The Nasdaq Composite rose 12.31 points, or 0.42%, at 2,944.14.

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