If there were they are not doing a good job, wish they get their act together and get it to $50 an ounce.
Maybe they don't care which direction it's manipulated, as they make money either way? I doubt they are stackers waiting for one big payoff at the end.
Well when the banks were caught recently - they were shorting it. They know by their own computers where their own investors have their short positions set at, and just blow them up (and it usually translates to most other banks as people using technicals will come to the same conclusion regarding short/stop positions) and then put a long position up and watch it go up again.
It is in the banks interest to keep the pm price down ... it keeps the masses in their paper ponzi scheme ...
