This is not a stock to buy, then decide you want out at the Bid. It is held by some strong Longs, and the MM's will be the only ones to let you out. But it will cost you a pretty penny. They will keep bringing it down till all your shares are absorbed.
On the Ask side you will not see it drop like the bid side. Shares are very hard to come by. The Bid will rebuild once the X seller is done.
