I think you had some front running of tax loss selling going into the September bottom. (market participants move increasingly sooner in increasingly mature markets – our markets are the most mature ever)
So it should be cleaned up soon.
The year 2000 to present comparisons are striking. (some tax loss selling witnessed in November of 2000 but dried up moving into December)
I am still calling for a momentum turn next month even if it starts out slow.
Cheers
