I actually tend to agree, there simply aren't any sellers left, at least not at this level.
The problem is there's no reason for anyone to buy, yet that is.
We know how quickly it can move, they simply need to re-generate some interest in the stock by releasing some sort of news, even if its not the Cancern deal.
When the trend shifts, we'll likely move back up quickly, but its up to them at this point.
