They are selling to themselves on the bid (the lower price). Essentially they shorted the stock about 10 days ago. Now they have to cover. So they short the stock again to cover the short that is coming due. It resets the clock for them, but... it will come due again in 10 days. That is the next leg I was referencing. This pps will bounce up as all the MMs cover and we will have a new pps level that will eventually need to cover.
