"the market is many times bigger the the U.S."
I would normally agree with that wide brush you used, unfortunately the PM market is only the size of a gnat on an elephant's butt.
Just today I heard on King World News that the whole PM market is smaller than one company on the NYSE, Walmart.
The Cartel doesn't have to tackle the market as a whole, it only needs to squish the gnat, the equivalent of just one Big Board company.
The Cartel is having a difficult time with the futures market and the physical markel, but mining stocks are "paper," that's the Cartel's speciality.
