With so many stocks in the health-care sector making big jumps today, Motley Fool Health-Care Analyst David Williamson has chosen five movers that he has his eye on, and you should, too. He looks at Biocryst (NASDAQ:BCRX), Savient (NASDAQ: SVNT), Intermune (UNKNOWN:ITMN.DL), OraSure (NASDAQ:OSUR) and Seattle Genetics (NASDAQ:SGEN) and finds four big plunges, and only one story of optimism, amid the second day in a row of major market carnage.
