选项：
A.Commodity index returns differ from the changes in the prices of their underlying commodities
Commodity indices commonly use an equal weighting method
Commodity indices in the same markets will share similar risk and return profiles

The performance of commodity indices can be different from their underlying commodities because the indices consist of futures contracts on the commodities rather than the actual commodities. Commodity index returns reflect the risk-free interest rate, the changes in future prices, and the roll yield.
