TheStreet Ratings Team has this to say about their recommendation: "We rate UNITEDHEALTH GROUP INC (UNH) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its increase in stock price during the past year, revenue growth, reasonable valuation levels, growth in earnings per share and largely solid financial position with reasonable debt levels by most measures. We feel these strengths outweigh the fact that the company has had sub par growth in net income."
