The short interest data have been released for the May 31 settlement date. Pharmaceutical companies usually are involved in a lengthy process in getting their drug candidates to market through clinical trials. There is a fair amount of risk involved, should a study come back negative or a candidate not be approved. Conversely, if a drug is approved or passes a clinical trial, there can be big upside.
