Is It Too Late to Buy These 3 Pharmaceutical Stocks?

Three of the best-performing pharmaceutical stocks over the past year have been clinical-stage biotech and biopharmaceutical companies -- businesses that aren't making profits but have promising drugs, or more often, drug candidates.

Though a few candidates will become breakout successes, the overwhelming majority of clinical-stage drugs never make it to market, and 11 biopharmaceuticals went bankrupt last year, according to a BioPharma Dive report. So it should come as no surprise that such companies carry some of the biggest risks -- and offer some of the biggest rewards -- in the healthcare sector.
