Index Snapshot:

The iShares S&P GSCI Commodity-Indexed Trust (Ticker: GSG) seeks investment results that correspond generally to the performance, before fees and expenses, of the S&P GSCI Total Return Index. The Index is world-production weighted meaning the quantity of each commodity in the index is determined by the average quantity of production in the last five years of available data. The S&P GSCI contains 24 commodities from all commodity sectors: energy products, industrial metals, agricultural products, livestock products and precious metals. S&P GSCI returns are calculated based on the arithmetic average of stable long positions in futures contracts. The index measures the returns accrued from investing in fully-collateralized nearby commodity futures. In order to avoid delivery and maintain a long futures position, nearby contracts must be sold and contracts that have not yet reached the delivery period must be purchased. This process is known as "rolling" a futures position. The index measures a fully collateralized commodity futures investment that is rolled forward from the 5th to the 9th business day of each month.
