TheStreet Ratings rates Pfizer as a

buy

. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, solid stock price performance, attractive valuation levels and compelling growth in net income. We feel these strengths outweigh the fact that the company shows weak operating cash flow.
