The company has a P/E ratio of 14.1, equal to the average computer hardware industry P/E ratio and below the S&P 500 P/E ratio of 17.7. TheStreet Ratings rates International Business Machines as a buy. The company's strengths can be seen in multiple areas, such as its revenue growth, notable return on equity, solid stock price performance, growth in earnings per share and good cash flow from operations. We feel these strengths outweigh the fact that the company has had generally poor debt management on most measures that we evaluated.
