There's no substitute for doing your own due diligence. If I were a betting man, I'd bet on copper in the relatively near future (i.e. months) and definitely over the next couple of years. Thanks for the article though - it's always interesting to read a contrarian view.

Ironically, I consider myself a contrarian - though I wouldn't say copper is exactly in favour now. I think the consensus is optimistic, but it's certainly not reflected in the price.
