Be careful as it is a very dicey market. Even when a stock gets approved like SRPT, it doubled on the news, then quickly gave it ALL back and then some. When a company gets the drug to market like VVUS, it DOUBLED then sales didn't materialize because of restrictions the government put on them and sales were pathetic. Vivus shocked down from more than $20 to the $10 it is at now. DNDN shot to $18 now it is down around $4. So even when they get approved, even when they get it to market, with the government constantly in the way, it ruins companies.
