I agree it does seem incomprehensible why they don't get on the other side of the trade for pm's. They could make really major profits. However as you said "If they are willing to forego these huge potential profits, I guess it provides perspective as to just how important it is for them to try and control the price of Gold and Silver. Sad."
I suspect that JPMorgan has not only $10's of billions of naked shorts on silver and to a lesser extent gold but also $100's of billions of derivative bets on keeping down the price of silver. Of course they are aided and abetted by the Administration/Fed who are providing the money to suppress G&S. How much of the Feds secret $16 trillion dollar payout discovered by the recent audit did JPMorgan receive?
