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