iShares GSCI Commodity-Indexed Trust Fund(AMEX:GSG)

GSG is a commodity pool tracking a version of the S&P GSCI, giving it fairly neutral exposure to the broad energy commodities market. Instead of holding contracts in the underlying commodities, GSG only holds long-dated contracts on the GSCI itself, as well as sometimes quite substantial cash and T-Bill assets. The fund has exposure to the same commodities in the same weights. These commodities are weighted by reference to world production statistics. Only contracts sufficient liquidity are eligible. GSG offers great coverage of plain vanilla broad commodities. As a commodity pool, GSG reports any cap gains marked to market on a K-1 at a blended rate.
