Don't know what chart you are looking at. I don't think this chart looks particularly weak. I might agree that it would be smart to wait for a pull back (if we get one) but it has closed pretty close to the high of the year.
In the view of the metals selling off some last week, I think the shares are holding up pretty well.
Perhaps they are beginning to lead the PMs now. They were certainly beaten to a pulp through most of the year. Maybe rotation time?
This stock is so over bought it has to fall back even if Silver moves up 5 dollars. I'm prolly going short tomorrow. We need Silver to move up 5 bucks and this stock to fall back about 5 dollars to get things back in balance. It's only off bout 7 dollars when Silver was almost 50.
