I think there is a misunderstanding with the perception of trading. Any fund can execute through whatever house they want. RBC doesn't exactly have to hold the shares. They just sell them on someones behalf.

Yes someone has been selling and selling since the stock was $2.5. Today and yesterday we have seen 1% of the outstanding trade. This seller will eventually have no more to sell. They may or may not be shorting. No one knows why anyone is selling at any given time. Maybe a fund is liquidating every position. Maybe someone needs to buy another yacht. What we do know is why someone is buying, and that is because this stock is stupid cheap!
