Over on CAPS, 97% of the 710 All-Star members who have rated UnitedHealth believe the stock will outperform the S&P 500 going forward. These All-Star bulls include Kinzo and hptrader, both of whom are ranked in the top 1% of our community.

In May, Kinzo shared this about UnitedHealth:

Huge competitive moat through it's large customer base will give this MCO (Managed care Organization) a distinct advantage over it's competitors and inhibit new entrants. Oh and it's undervalued right now too. The fear is nationalized health care, but I honestly do not see that happening overnight if at all.

A pitch from hptrader just last week shared that healthy optimism, highlighting the stock as a particularly timely opportunity:

While the whole health care sector was mired in a down-trend since the start of the year, July seems to have been a turning point and United Health looks to have formed a bottom and is gaining momentum to the upside. This company is cheap by any measure, and both the technicals and fundamentals are lining up which could provide a great opportunity over the next few months.
