Unwired,
Patience mister. The purchasing of physical's just the 1st stage by smart money. Next, PM stocks (majors and quality juniors) will largely get invested by institutions. Last, the general public will begin buying equity of any entity related to metals. Big money for those that can wait this process out!
But for now, physical's selling-out will "float all boats" in time. We have our safety boats in the Yamana's, Tyhee's and Kimber's of the sector.
I really believe we're days if not week's away from some more major action in gold. Sit tight
