1) Miners as a group have severely underperformed gold and silver recently. Usually this precedes a correction. Or sarcastically put, this has predicted 9 of the last 5 corrections. (Not a typo)
2) Long term, if 1970s/early 80s is a guide, the very last rotation is the one into junior miners. But you gotta be sure to keep standing until that 15th round. Gotta stay financed.
3) The reason why #2 above happens is that at the end of the cycle companies are so starved for added future production that ounces in the ground are finally fully valued, big-time.
