Too much credit has been given to Ackman thus far as it is far from over. Imagine how thrilled his investors will be if they realize what gain they could have recognized had Ackman not been as steadfast, stubborn, and arrogant in his zero price target. If there is one thing that is consistent about the market, it is that nothing is certain and any so called gain on either the short or long side can be short lived. This is particularly true for investors pushing their luck, whether it be to hold out to zero or to infinity.
Do your research a little better. I know it's a lot to ask for a dumbazz like you. He started shorting well before the Einhorn call, then more as the call happened, more all the way leading up to his presentation. Then atleast 1/3 of the 24 Million shares after the presentation down into the 30's.
For you not to know this, you shouldn't even be allowed to waste our time posting nonsense.
