MM's do not naked short. They don't need to - they simply borrow shares from sellers and pay them back after they are sold.
It is all automated, there are no 'eyes on' these sub penny stocks, and besides, there is far too little money that could be made by 'shorting' sub penny stocks. People that blame mm's for share price fluctuations simply have no idea what mm's actually do, and how they do it. They are BROKERS, not TRADERS!! If an employee cheats, they are cheating on their employer, and would be promptly fired if caught. Do you really think a multi-million dollar mm enterprise is going to let their employees cheat in such a way that it could bring multi-million dollar fines from the SEC? You guys need to take your blindfolds off and quit imagining that mm's do more than make the trades you request. That is like blaming etrade or fidelity for manipulating share price. TRADERS are who manipulate share price, so when it goes up or down, you can bet it is the whales that are controlling the price.
If you have a few hundred million shares, you can set buys at a low price and sells at a higher price, and just sit and watch. As price rises, automated trades will sell, and when it drops, automated trades will buy. Even I do that on some stocks. I make 100% over and over and virtually don't lift a finger. I always keep a core position as long as the stock is viable.
