I wouldn't worry about today not any volume behind this drop. I am happier today about prospects than yesterday, a reconfirmation of timing of filing NDA. If they came out today and said delayed, I would Be a bit disappointed. I would be a buyer here.
added a little more at 10.52 - my highest price. The low volume doesn't concern me so much as you pointed out. It is probably traders hoping for a big announcement for todays meeting. It rose on low volume this week as well. On the ing for sure, we should expect the NDA by EOM. And hiring the commercial folks is a positive sign,
