Very simple, the futures are up huge overnight, on thin volume. The cash market gaps open, their you have your new high. Volume on advances is lighter than declines, AD line or breadth, has been lousy. Guess the back lash from this lousy foundation is days like today. The market internals are just plain lousy, buy have no fear the futures are here. Also on the weekly dow chart we have a bearish candle, with a divergence. This is worth monitoring.
