Insmed Inc ( INSM), Allos Therapeutics Inc ( ALTH), ProPhase Labs Inc ( PRPH), and Response Genetics Inc ( RGDX) were all decliners today within the health care sector with Life Technologies ( LIFE) being today's featured health care loser.

Life Technologies Corporation operates as a life sciences company with a focus on improving the human condition worldwide. Life Technologies has a market cap of $7 billion and is part of the drugs industry. The company has a P/E ratio of 20, equal to the average drugs industry P/E ratio and above the S&P 500 P/E ratio of 17.7. Shares are down 29% year to date as of the close of trading on Friday.

TheStreet Ratings rates Life as a hold. The company's strengths can be seen in multiple areas, such as its revenue growth, reasonable valuation levels and expanding profit margins. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, weak operating cash flow and a generally disappointing performance in the stock itself.

On the positive front, Cardium Therapeutics Inc ( CXM), Anthera Pharmaceuticals Inc ( ANTH), Adeona Pharmaceuticals Inc ( AEN), and BG Medicine Inc ( BGMD) were all gainers within the health care sector with Johnson & Johnson ( JNJ) being today's featured health care sector winner.
