To be honest, I sold on the way up. I messed up the day before and bought a load at $5.60. I also bought a bunch at $5.1. When it made it to $5.5, I was happy to dump it (given it closed at $5.1).
We may catch another delayed run as it did last time so I will keep on watch. These bios always have a big pop after news, then typically pull back, but more often than not return to the old high - IMO. The only thing I don't like about them is they are dangerous to hold overnight - they release bad news, and you are cooked. I got killed on pphm last year - my worst day of 2012 - so I always fear bio techs.
