I think this ratio is one of the most important out there as it shows the rotation into the staples of life, so to speak. additionally, at EVERY major inflection point since 2000 when this ratio bottoms or tops the market does the opposite. this pattern is complete, it held and I think it will prove to be very bearish for the market.
I can’t quit you XLP/SPX ratio …
