I think this quite illustrates the amount of power under this rise. If you think that the rise up should be symmetrical and equal the move down, then I am thinking 7 more weeks up, with the correction here and there, but before we see if this becomes a secular bull instead of just a leg in a counter move. I think several of my other measures including "Acid Test" would serve to confirm that.
Using a more common measure, the Point & Figure Chart, we could develop an upside Potential Objective of $22.72 GDX. Given normal corrections it would not be surprising for the GDX to to talk half that time to do it, at which time a further upside move would be projected, like a fire truck ladder extending itself. That would put us past the US Thanksgiving and halfway to Christmas, when the BIG Rally in the PM's started last year.
I hope this gives you a small picture of what I am thinking. There is tonnes more in each issue of Peak Picks, with no risk when you sign up.
