musthavemusic, Re DVAX: I follow it closely and have a large position.
Certainly a risky play, but IMHO there's at least a 60/40 chance (some folks say higher, some lower) of a restricted label approval on Feb. 24. I'm guessing a decent run-up (around $4) and maybe a small pop (because of the label) upon approval.
I'm counting on the run-up, will definitely not hold through approval, but I think it's a good play anywhere around $3.
Best of luck.
