I think there's enough new money coming in to at least keep any pullback orderly, but a correction certainly isn't out of the question. I was looking at older charts last night from 2011, and the current parabolic move looks very similar to the one in 2011. Of course there are more people in the market now, which should help smooth out volatility to some extent, but nothing goes up forever - or at least nothing has in history to this point.
