Abbott has locked up rights to this program so there is really no reason to buy unless/until approval happens. However, you raise an interesting point because the stock price is so low. Also, if the pipeline pans at all it could be a good fit for Abbott. If I were Abbott I'd buy a piece of NBIX now as insurance in the event they decide to buy later. I don't know how opportunistic Abbott is, but NBIX is dirt cheap. They have to be careful though because the last thing you want is to go hostile with your partner. Abbott has purchased more speculative things in the past for quite a lot.
