I figure there are always some who can be shaken out....even this close to the finish line.  As 2018 was coming to a close some might have bought in based on hopes of a spike after the trial ended, anticiapting that to happen sometime around Dec 31/Jan 1 based on guidance.  But life is life and life can be expensive....not everyone can afford to have cash sitting while waiting and hoping.  

The volume continues to be pathetic, which says to me that while they might be shaking some free most are holding tight.  Short interest update still not out, we'll see what it has to say.
