TheStreet Ratings team rates AMERICAN EXPRESS CO as a Buy with a ratings score of A. TheStreet Ratings Team has this to say about their recommendation:

"We rate AMERICAN EXPRESS CO (AXP) 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 revenue growth, notable return on equity, impressive record of earnings per share growth, increase in net income and solid stock price performance. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."
