More fun with charts... Price of Gold vs. Net Short Positions
How about this one:
This one shows the relationship betwen the price of gold and the short positions on gold contracts... thereby illuminating the manipulation that is/was rampant within the gold market. The manipulation is becoming less effective as they run out of gold to throw at the market... but for the entire modern era the price has been manipulated. A big part of this commodities bull market has to do with finding the true market value of gold after eons of manipulation.
