The Dow was beating the other major indexes on a mixed day for the broader market with some help from UnitedHealth Group.

With the Dow up 85 points, or 0.2%, UnitedHealth’s 7.9% gain tacked on 141 points to the Dow on Monday. Only 16 of the index’s 30 stocks were rising, but UnitedHealth’s big gain and stock price north of $300 provided a big boost for the index.

The S&P 500 was down 0.1%, while the Nasdaq was down 0.3%.
