I believe it's going to start slowly climbing as we approach the next interim. Particularly if things progress in other countries. If they don't progress,and enrollment is slow it will erode. It's all about time. If investors perceive that a potential approval is near, it will rise. If they think it's a ways out it will fall.
Put another way, a decent percentage of Investors move money around. I have a core position here that I won't touch, but I also trade this and several other stocks when I think it makes sense.
