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 (BCRX 0.07%), Savient (NASDAQ: SVNT), Intermune (ITMN.DL), OraSure (OSUR -2.40%) and Seattle Genetics (SGEN) and finds four big plunges, and only one story of optimism, amid the second day in a row of major market carnage.
