Yeah defiantly "thug wall" Marzan.
Easier to do with relatively low volume where Collaborator A and B play with bid and ask prices to drive the price low and the B does the same with C and then C back to A so that by the end of the day they drove the price down but A, B and C still have about the same number of shares . . . and that is they did it with real people manually. But we now know from Knight Capitals $440 million flash crash that they have software that can do this:

Power Peg

The new RLP code in SMARS replaced some unused code in the relevant portion of the order router; the old code previously had been used for an order algorithm called “Power Peg,” which Knight had stopped using since 2003. Power Peg was a test program that bought high and sold low; it was specifically designed to move stock prices higher and lower in order to verify the behavior of its other proprietary trading algorithms in a controlled environment. It was not to be used in the live, production environment.

Yeah if we have a market maker involved they can do this fairly easily with software and may be working in the interest of Big Pharma thugs to keep the price as low as possible for a potential buyer.
