It could be people with zero based shares trading them around to give the illusion of outsider interest. Solid probability given the wild swings of 20% we are seeing.
I guess that could work in the other direction too. It could be people with zero based shares trading them around to give the illusion of a sell off. Solid probability given the weak attempts to push this down when the mid-40's have been the overwhelming average of this stock since falling to the grey sheets a month ago.
