The ICE® BofA® Commodity Index eXtra (MLCX) is designed to provide a liquid, consistent, representative and cost-efficient benchmark for measuring commodity market performance. MLCX constituent selection and weighting takes account of the liquidity of the constituent futures contracts and the value of the global production of each underlying commodity. These criteria ensure that the Index reflects the relative significance of these commodities in the global economy. MLCX is supported by a comprehensive family of sector, single commodity and modified indices. Total return, excess return and spot versions of the indices are compiled.
