We study the basic properties of an equally-weighted index of U.S. commodity futures from the perspective of a Japanese investor. We find that the returns on the U.S. equally-weighted commodity futures index maintain their basic properties, documented in Gorton and Rouwenhorst (2005), when...

For this study of the simple properties of commodity futures as an asset class, an equally weighted index of monthly returns of commodity futures was constructed for the July 1959 through December 2004 period. Fully collateralized commodity futures historically have offered the same return and...

This note is a response to a recent paper by Erb and Harvey (2005). We show that diversification returns are mathematical properties of geometric averages of index returns, and not due to rebalancing. We also show how rebalancing affects the performance of the equal-weighted commodity futures...

We construct an equally-weighted index of commodity futures monthly returns over the period between July of 1959 and March of 2004 in order to study simple properties of commodity futures as an asset class. Fully-collateralized commodity futures have historically offered the same return and...

Commodity futures risk premiums vary across commodities and over time depending on the level of physical inventories, as predicted by the Theory of Storage. Using a comprehensive dataset on 31 commodity futures and physical inventories between 1969 and 2006, we show that the convenience yield is...

Commodity futures risk premiums vary across commodities and over time depending on the level of physical inventories. The convenience yield is a decreasing, non-linear function of inventories. Price measures, such as the futures basis, prior futures returns, prior spot returns, and spot price...

Gorton and Rouwenhorst (2006) examined commodity futures returns over the period July 1959 to December 2004 based on an equally-weighted index. They found that fully collateralized commodity futures had historically offered the same return and Sharpe ratio as U.S. equities, but were negatively...
