The noteworthy things about the $NYAD weekly (in cumulative mode) is that it shows negative RSI divergence versus SPX price. The other item is that seemingly its in some kind of wave 5 move at some cycle degree or so because it has indeed squeaked out an all-time high.
The Wilshire5000 made a P2 high this past week. This high occurred with the money flow exactly at the level it was at the 2007 peak. The accum also shows some negative divergence along with the RSI still. The BB's are as tight as they have been in over 2 years. Also note the nice doji candlestick that printed last week.
