If the volume was through the roof, I would sleep better leading up to ASCO. With low volume, but a significant upward move in a down day...it is a positive. Can we read anything into this, or should we wait for Tuesday's profit taking?
the only thing that I read into it, is that the hedge fund(s) who short this took off yesterday and there weren't there to short every rise. however, next week should begin the run up to asco. so any up day is a positive to me.
