So basically the market is create a hysteria for a certain stock have people invest in it then Get to a certain point and take your money out while people left with worthless shares. Am I right
Well, the big deal in all this is that they're doing it with stocks that other people were shorting. So the short-sellers HAVE to buy back the stock at a certain point. That gives a particular hedge in your bet - it's not just "last people in" who get fukked (though those indeed will get fukked too), it's a particular move to make profits by fukking over the short sellers.
