Well the 25 days are up next week so I will wait. If I buy now, I will keep losing money until then. If they come out with the news of FDA approval before then, you're right, it will probably go up but how do we know they will announce it? They said they expected it December and its January now. You can buy all you want now, I'm just stating my opinion here and by no means you should make your trading decisions based on that. If they don't release any news before the warrants are done you will most likely be able to buy twice as many shares next week for the same price you would pay today.
I lost a lot of money on this stock and I'm not doing it again. If it keeps going down, I may buy some next week.
