I noticed long ago those big caps move slow like big mutual funds. GOLD similar $35 billion. I always had better luck with smaller caps like CDE $2 bill down to $500 million.
NEM is still not bad, up about 225% from the Jan 2016 $1,060 Gold bottom. Basically it just went down with Gold after August 6th. Gold down 10% and NEM down 17% .
