I agree, there will likely be more volatility even now as it has gotten more attention but especially once it gets listed. While the swings may be larger, fundamentals are key to keep one's bearing through it all. I don't think about the fundamental value as a destination into the ever extending horizon but rather a centerpoint or mean around which we will see the swings occur. Having a good peg as to where it exists inevitably pays hansomly... as long as you keep your emotions straight.
And yes, I think topline growth will be key here but this stock stands a major correction in either direction depending on where margins come out.
