RE: Yamana Vs Goldcorp I think you may regret it but if pog moves up, this will follow as others will but maybe not as well as you would like.
I got lucky and sold G near it's high, also sold ELD on the way down (but still made money) and moved some to YRI and am happy I did.
I think going forward YRI is the better bet in its class.
Not a day trader I hold for long periods and waiting a few years before I sell any.
I used to think pog would peak in 2014 but now believe in a later date, maybe 2016-17 depending on how long things get prolonged.
I also don't believe we will see gold below 1000, maybe ever again. Too many factors that won't allow it, including production costs. We will see more inflation. (real inflation the kind the ordinary person feels when we go to the supermarket)
JMHO
Wish you well, good luck
