Crap. Fluctuations in commodity prices comes from supply, demand, and rumor.
The history of gold prices is that if the dollar is strong and stable, investors go that way and do not tend toward investing in gold and commodities, keeping the price of gold relatively stable.
But when the dollar is weak and unstable, gold prices tend to go up because investors shy away from traditional financial investments and feel safer investing in tangible things like gold and other commodities.
