I see your point.
My point is that the MM wants volume. If it is trading at $.013, he is happy. If trading dries up he will move the pps. Up or down attempting to get trading going again. Usuially, he will have to move it down to intice buyers, however moving it up may do the same thing. Bring in buyers that don't want to be left behind.
I just don't attribute all this stuff to MM's. They want and make their bread from volume. They don't want to own a share. They have to buy to "maintain an orderly market'. They may have to short to do the same thing. By the close, generally, they want to be even. No short, no long. Also, they are just like you and I and not all that smart to do all the things, manipulate, etc. that they are credited with. They lose and they win. That's why they just want to trade and make their commissions. They don't want risk if they can avoid it. They make plenty without it. Could lose with it.
