TheStreet Ratings rates Merck as a buy. The company's strengths can be seen in multiple areas, such as its solid stock price performance, increase in net income, largely solid financial position with reasonable debt levels by most measures, reasonable valuation levels and growth in earnings per share. We feel these strengths outweigh the fact that the company shows weak operating cash flow.
