MM don't have any weakness on the stock market, they have the power and the control buttons! even when they short sell most it paper work very little cash has to be put out by MM when they short sell, they got it made.
Plus they get info we never get !!!!!IN ADVANCE
I do DD on MM, wall sreet and stock markets,and brokerage firms, and powerful crooks, you do dd on Company's , and that does not change what the share price is, the MM are what changes the share price, to suit them, not US !
