If you are expecting ER or other news with this or next few weeks then you better sell because that won't happen. But if you are looking forward for Omontys to be back in the market and the stock jump for big bucks then hold. Just know that Omontys will definitely be back in the market as soon as Affymax can make it happen.
I'm in for 650 @3.39 and am holding! I think there will be time yet to jump ship after tomorrow, if this thing goes down! Besides, no news is good news! I mean, maybe place a stop, unless that's what you don't want to do!
