Merck & Co., Inc. provides various health solutions through its prescription medicines, vaccines, biologic therapies, animal health, and consumer care products worldwide. The company has a P/E ratio of 23.1, above the S&P 500 P/E ratio of 17.7. TheStreet Ratings rates Merck as a buy. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, good cash flow from operations, increase in stock price during the past year and expanding profit margins. We feel these strengths outweigh the fact that the company has had sub par growth in net income.
