Another way of saying this is that: When an economy does good the price of Gold goes down... so when the economy is doing bad, buy gold. When an economy is doing good, cash becomes relatively more valuable. If there are any people with money who know 21st Century economics then they could in theory, hold a country's economy hostage and make a huge amount of money.
4 Law Enforcement: To know who simply watch who buys and sells gold, when and why. When the patterns emerge you have proof of a crime (securities/economic fraud i.e. con game).
In fact, it has been shown that 'rumors can move markets'.
Gold price hits all-time high on US debt concerns
The price of gold has risen to a fresh all-time high of $1,594.16 an ounce, and the dollar has fallen, on concerns the US may default on its debts.The moves came after ratings agency Moody's said it may cut the debt rating of the US, warning there was a "rising possibility" it will default.
Uncertainty and concerns (fears) about the future cause the markets (which are free floating) to fluctuate. Since the supply of Gold is limited it has great 'store of value' (one of the measures/definitions that economists use to define money)
As the article further explains...
Gold is seen as the number one safe haven purchase in times of economic uncertainty, but analysts said its rise was also caused by the fall in the dollar, which makes the precious metal more affordable for holders of other currencies.
Taking market variability into account and the promotions to buy gold to a large number of consumers (such as Rush Limbaugh promoting gold through this page or Glenn Beck pushing gold as the only asset that matters because a 70 year old gynocologist says so), the following analysis about a possible gold bubble makes sense...
Gold isn't a stock with real earnings. It isn't a bond with interest payments. It isn't oil. It won't help you drive a car; it won't help you light a fire. Yes, you can wear it, but you can't eat it. If doomsday really arrives, a can of baked beans might be worth a lot more than a brick of gold.
Why have oil prices spiked wildly? Some argue that the volatility is a result of supply-and-demand fundamentals. More and more observers, however, believe that excessive speculation in the oil futures market by investors is driving oil prices sky high.
A June 2 article in the Wall Street Journal said it all: “Wall Street is tapping a real gusher in 2011, as heightened volatility and higher prices of oil and other raw materials boost banks’ profits.” ExxonMobil Chairman Rex Tillerson, testifying before a Senate panel this year, said that excessive speculation may have increased oil prices by as much as 40 percent. Delta Air Lines general counsel Richard Hirst wrote to federal regulators in December that “the speculative bubble in oil prices has concrete detrimental consequences for the real economy.” An American Trucking Association vice president, Richard Moskowitz, said, “Excessive speculation has caused dramatic increases in the price of crude oil, which harms end-users like America’s trucking industry.”
This is a claim that should be taken seriously about the unreliability of some of these stock market reactions (afterall, with much of the wealth with a small number of people (i.e. income inequality), it doesn't take much to skew/play-with a market)
