TheStreet Ratings team rates EXXON MOBIL CORP as a Buy with a ratings score of A-. TheStreet Ratings Team has this to say about their recommendation:

The company's strengths can be seen in multiple areas, such as its attractive valuation levels, good cash flow from operations, increase in stock price during the past year and largely solid financial position with reasonable debt levels by most measures. We feel these strengths outweigh the fact that the company shows low profit margins."
