Gold has sky-rocketed in recent years.
I see you're choosing your historical periods pretty carefully here. What do you consider recent years?
5 years? Gold down from $1600 to $1100 an ounce
6 months? Gold down from $1300 to $1100 an ounce
(see, I can pick historical periods too. There is no standard time frame)
From a historical standpoint, from 1933 until 1974, Americans could not legally own gold. Because of this, charts during this time period are pretty much useless. The dollar was no longer tied to gold by 75, so that's where "real" gold value begins in the US.
It's easy to get in your Delorean, fire up the flux capacitor and buy in the past. Not so easy going forward. In general, gold goes opposite stocks so you know that when the stock market is "skyrocketing", like now, gold is dropping like a rock. When you see stocks dropping, investors flea to gold and it rises. Once stocks level out, though, those same investors go back to stocks and gold again drops.
