The company has a P/E ratio of 959.5, equal to the average electronics industry P/E ratio and above the S&P 500 P/E ratio of 17.7.

TheStreet Ratings rates Cepheid as a hold. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and impressive record of earnings per share growth. However, as a counter to these strengths, we find that the company's return on equity has been disappointing. You can view the full Cepheid Ratings Report.
