Ncs try but this doesn't resemble a blow off top. This is just a huge steady rise due to massive accumulation. As for Cramer he is long FB big time as he is quite a bit brighter than you, it would appear.
keepshorting, you're just upset because of all the money you lost in shorting FB all the way from $24. Having said that, we probably are near a short term top. Hedge funds that made 2 years worth of profits in this stock alone will take profits before the earnings report. They won't want to risk losing all those gains.
