There is alot of money to be made when a stock goes up. There is even more money to be made when a stock goes down if you were selling vapor all the way down to .0001 and cover there. - AlanC
Untrue. Your greatest profit shorting is 100%. Your potential profit pumping and dumping is limitless. - Janice Shell
Greatest profit shorting is 100%? Not when one sells and sells and sells shares that they do not own, have not borrowed, or ever intend on borrowing. That formula has "unlimited" gain potential. One which a percentage cannot be calculated without "error".
When buying comes in to push the PPS up, just "create a market" and sell more and more and more, until the buying pressure collapses along with the PPS again.
Wash, rinse, repeat!
