WDCO (Wilson-Davis) was a MM that was big on the bid back when SEFE was surging up. They would post 500k shares or more on the bid and kept moving the bid up up up, pushing the price up towards $3.
The PPS started crashing as soon as WDCO took away its support.
Now today I see WDCO in at 1.3 million shares bid on another heavily promoted stock that is up 20% today.
