Futures Trading and Investor Returns: An Investigation of Commodity Market Risk Premiums

The long-standing controversy over whether speculators in a futures market earn a risk premium is analyzed within the context of the capital asset pricing model recently developed by Sharpe, Lintner, and others. Under that approach the risk premium required on a futures contract should depend not on the variability of prices but on the extent to which the variations in prices are systematically related to variations in the return on total wealth. The systematic risk was estimated for a sample of wheat, corn, and soybean futures contracts over the period 1952 to 1967 and found to be close to zero in all three cases. Average realized holding period returns on the contracts over the same period were close to zero.
