Keeping up with evolving approaches to asset allocation, our commodity indices offer the potential to improve diversification and have historically provided liquidity and inflation protection.

As a leader in commodity indexing, we offer a wide range of solutions anchored by two true reflections of commodity beta. The S&P GSCI measures the most liquid commodity futures and is world-production weighted, whereas the Dow Jones Commodity Index (DJCI) emphasizes liquidity and diversification and equal weights three major commodity sectors.

  • Diversification


    Historically, commodities have had low correlations to stocks and bonds because the sources of return are inherently different. Because commodities are necessary, often-used staple goods, they can also provide diversification during economic crises.

  • Inflation Protection

    Inflation Protection

    Commodity indices tend to have a positive correlation to inflation because they reflect our changing expectations of future prices. Historically, one dollar of investment in a broad-based commodity index has provided more than one dollar of inflation protection, because food and energy carry more weight in these indices than in the CPI.

  • Liquidity


    To promote investability, the weight of each commodity in the S&P GSCI® is based on its volume of futures contracts traded. As a result, the index tends to have higher weights in crude oil, natural gas, and heating oil. The DJCI employs a simple, straightforward, equal-weighted approach, so that one-third of the index is devoted to agriculture and livestock, one-third to energy, and one-third to metals.
