Bought this mid float on a license option aggrement with pfizer. Float is higher than I like but I felt that the price action in premarket was good and the volume was there. Trying to take small singles since everything seems to be failing at the open. Saw a wall at 4.10 and should have taken the rest off but got too patient. I feel as if I traded this really well and I'm very happy with this trade. Would take this again.
