If your are a believer that O will come back then this sp fluctuations is meaningless. So relax and let it play out in a few months. On the other hand, if you are a trader or non-believers, buy/sell to your hearts desire.
I am long AFFY and a believer.
I am long, but it appears it may be well into next year when they reintroduce O. They recently jettisoned one of their main buildings, why else would they do that if the runway for reintroduction was a short timeframe? Secondly it appeared the DNA study was just kicking off, that sounds like a 6 month deal to me. I cannot time it so I am staying pat on this one.
I can't pretend to know the time frame for restoration if it takes place. But, if/when it does take place, as far as I know, Omontys will be produced, marketed, and distributed solely by Takeda. If that is the case AFFYMAX does not require any infrastructure and minimal personnel, which is why The Brenner Group bought out/negotiated to have AFFYMAX's lease terminated. ( And also to save money. )
