I have been calling for a correction down since mid August in many posts, and am longer term Bearish.. but the idea of VWAP is to point out extremes. We have quarterly, monthly, weekly, and daily VWAP above us, and we have brushed up against STDEV3.
So even though things look very Bearish the theory that we should return to the mean still stands. We should go back up to at least Daily VWAP, if not higher, the rubber band is wound so very tight.
