RE:Who does thatI'm FAR from an expert on this stuff; but having followed the stock for over 10 years I believe this is done by banks that are hired by the majors that are ultimately interested in acquiring PRB to keep the price down. So they, often anonymously, keep selling very small lots of shares over and over, and since there are never, ever, never any buyers of the stock, ever, there's no one there to buy at a higher price to support the stock. Then, ultimately Goldcorp or whoever will purchase the company for 1/2 of what it's worth. It's frustrating but unless buyers support the stock it will continue to happen. Someone else who knows more about this stuff should chime in because I'm admittedly a total amateur and I could be totally off on this.
