Sir Fully: Nice chart of long term rate vs gold.
Evaluating PM sector one has to compare with credit spread.

CDNX is an index related to risk on/off in PM sector.

The chart shows exceptional relation with credit spread HYG/IEF. When credit spread narrows risk is on and vice a versa. But during some period in past the credit spread and CDNX diverged and now seems the relation is back to synch???

This spread showing business activities are going to improve. SO as CDNX will rise with risk in sympathy of risk on. HOPEFULLY.
