I'm guessing the volume listed is for the two week period. A lot of variability, which translates to big moves in the days to cover, which is what traders look at for identifying potential short squeeze candidates. Without some sustained volume though, I don't they we'll get those type of traders to jump in and help us out.
But also note, that even those the total is up, it's still far less than several times during this calendar year.
I presume your interest though is looking for hints on another Socius tranche, is that right?
My guess is that the volume tanking is an indication that tax loss selling is about done. Maybe some of them will buy back in January after the 30 day wash rule period has passed.
