You saw the big gap that's it. There is no way it goes to 50 by next week. It may go down a bit tommorow as weekly option bets expire if momentum is great enough to carry it through. Ipo price is a huge resistance as that will bring a lot of people back to a point that is profitable so there will be some selling. The trend is still up but the big gains and gaps are done and momentum slows as options are unwound ala q2.
Judging from volume, shorts are abandoning ship. I could see it continue up to 40, maybe 42. Could be wrong, but if it gets that high, I will definitely consider shorting. This thing is still a balloon with an uncertain figure, given the pace of technology and how today's hot site is yesterdays joke.
