Wall St. edges up with healthcare boost

NEW YORK (Reuters) - U.S. stocks edged higher on Tuesday as an upbeat outlook from UnitedHealth lifted health insurers, but a sharp drop in oil prices weighed on energy shares and limited the advance.

The Dow Jones industrial average <.DJI> rose 23.9 points, or 0.13 percent, to 19,121.8, the S&P 500 <.SPX> gained 2.95 points, or 0.13 percent, to 2,204.67 and the Nasdaq Composite <.IXIC> added 11.11 points, or 0.21 percent, to 5,379.92.
