Very volatile sector. And, I hate waiting for Macro plays. I would either trade the gold juniors GDXJ. But most likely get a Gold Major with a dividend to pay me for waiting. Or maybe sell puts when the vol is juicy.
I am more interested in a coal play. Probably, after a change in the Admininistration. There are still small LLC coal miners in Virginia which my friend's dad was into. But if you didn't grow up in the business, they might sell you a lump of coal (Not).
