CM, just had a look at the es vol, that has been the highest buying in a any 60min period for last 3 months (250k) - probably an indication that this was a blow off and no further upside if not falling back a little again.
Going back to november, we had slighlty less volume 220k but the market still went up, though only by 2-3 es points.
Just an observation, anything can happen I guess.
