that is just the difference i want to show. To own something is one thing. You can sell your car, because you own it. If you borrow me your car and I sell it - What would you think about it?
That`s only one point of view.
But if you sell shares you don`t own, because you want to drop the price and buy cheaper later, then it`s a big cheat JMO! If you are a shareholder of such a company, and you can only watch the pps dropping, `cause of such "legal" transactions, you certainly would be pissed also!
