Commodity Selection Index - CSI
  
You know what'd look great as a bed-side table? A barrel of oil. It's one way to ensure that you'll always have a source of energy to light your bedside table. If you really want to go old school, you could write with a feather pen as well.
But how would you know if a barrel of oil is a good investment compared to all the other commodities traded on the market today? You could use something called the Commodity Selection Index.
Back in 1978, a technical trader named Wells Wilder Jr. came up with a way to determine which commodity is best for short-term trading and hedging. Given the volatility of commodity prices, the CSI is used to determine hedging strategies on investments lasting up to 12 months.
