BOSTON ( TheStreet) -- Biotech investors love the big score. No other sector but biotech offers investors the chance to pick up cheap or forgotten stocks that can turn hot and double, triple or even quadruple over the course of a year. (The reverse, unfortunately, also rings true. (See Five Drug Stock Losers of 2010.)
