S&P Dow Jones Indices (S&P DJI) offers a number of strategies that track various commodities markets. The most widely recognized of these is the S&P GSCI, which is designed to measure the performance of a broadbased, production-weighted, investable representation of the global commodities market. Energy-related futures make up more than half of the index composition.
For a less-energy-intensive commodity market measure, there is the S&P GSCI Light Energy. It tracks the same designated contracts as the headline S&P GSCI, but it divides its contract production weights in the energy sector by four, increasing the relative weights of other S&P GSCI commodity components. Therefore, the index offers a commodity exposure that is more evenly weighted across the five major commodity sectors: energy, industrial metals, precious metals, agriculture, and livestock.
Exhibit 1 compares the methodologies of the S&P GSCI Light Energy and the Bloomberg Commodity Index (BCOM). These two indices are representations of a more equal-weighted view of commodities markets. Their performance is similar, and due to lower energy weights, each index has shown much less volatility than the headline S&P GSCI.
