If you want any more evidence that a pump piece can dramatically affect a lightly traded stock, just look at AEZS and KERX. It isn't just that the both are up more than 20%, but the volume is already 10X higher than usual.
I have heard that they are pricing/planning a PIPE and expect it announced quickly - explains the pump pieces last few days. Hearing 10m shares would expect $3.75 - $4.25 area
