I think you may see this stock run hard on no news. Unless you see a couple dollar spike in a few minutes I would assume it's just position adding ahead of the trial update. I believe next update is completion of enrollment, not interim analysis however.
I'm still searching but haven't seen anything. Of course I'm hoping that some positive news leaked out somewhere and that this is foreshadowing a big event! NLNK is my fourth largest position, after NPSP (by far my largest), followed by PCYC and JAZZ. Then NLNK, KERX, CLDX, ALXN.
