. There is NO naked shorting happening in penny stocks. The OTC is automated, there are no people looking at the 10,000+ penny stocks and their billions of daily trades and trying to cheat partial pennies on trades. Every trade is recorded for audit, and such shenanigans would be instantly visible. In fact, MM's HAVE to buy any stock they monitor that is within their spread, and they HAVE to sell any stock they have that is within their spread. They CANNOT buy or sell outside their spread. They CAN however, change their spread. And of course, there isn't just one MM, there are dozens, competing against each other.
It's hard to imagine multi-million dollar (MM) companies trying to cheat pennies out of the penny market. The penalties for getting caught would FAR outweigh any 'so called profit' to be made by naked shorting. Try to understand what MM's actually do instead of making remarks that simply cannot be true. And don't bother 'informing me' that it really happens - it doesn't. These comments only serve to make the uninformed more uninformed and spread myths wider.
