PerkinElmer, Inc. provides products, services, and solutions to the diagnostics, research, environmental, industrial, and laboratory services markets worldwide. The company operates in two segments, Human Health and Environmental Health. PerkinElmer has a market cap of $3.9 billion and is part of the health care sector. The company has a P/E ratio of 56.8, above the S&P 500 P/E ratio of 17.7. Shares are up 5.7% year to date as of the close of trading on Thursday.

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

On the positive front, Healthways ( HWAY), down 17.0%, CAS Medical Systems ( CASM), down 11.5%, Oculus Innovative ( OCLS), down 9.8% and IsoRay ( ISR), down 8.7% , were all gainers within the health services industry with Humana ( HUM) being today's featured health services industry leader.
