The sellers are the company and they do not care what price they get...it's all free money.
It's a pritning press that never sleeps on these things.
The only way which someone mentioned is the mms have inventory they want to make a profit on but they prbably cut a deal on a huge lot of shares at even a lower price so they have no reason to move this higher as everyone will make free money except anyone who thinks this is going anywhere.
