You make money when you buy. "Buy and hold" is what I've heard.
From a 5-yr chart
Commodity and Metal Prices, Metal Price Charts - InvestmentMine, Gold and Silver bubble commodities spiked during the USD panic when the big holders made a killing off the floods off desperate unwashed masses wanting to get in where it was safe. Then commodities slowly corrected over time. That seems to the animal spirit.
Platinum and palladium are rare, found in China, and used in catalytic converters.
Cars aren't going away anytime soon.
Questions to ask:
Is there going to be another market correction?
And if, then how big? What is the most safe investment?
Is China going to expel all foreign companies and go hard core Maoist again?
What other companies are possible competitors?
Sell all or some? Diversify with a fund?
