The company's strengths can be seen in multiple areas, such as its revenue growth, solid stock price performance, good cash flow from operations, largely solid financial position with reasonable debt levels by most measures and expanding profit margins. We feel these strengths outweigh the fact that the company has had sub par growth in net income. You can view the full Cooper Companies Ratings Report.
