I dont know if you remember how I was successful in shorting a few biotechs that just had drug approvals. Finally, I think I found another one....HZNP. They just got their drug approved yesterday and it is already dropping. I may buy puts on it.
Their drug Rayos is not going to find much of a niche in the market. It will be affected by generics on one side, and then get destroyed by Synavive down the road, if it gets approved..
