The Dow Jones-UBS Commodity Index DJ-UBSCI is a broadly diversified index that allows investors to track commodity futures through a single, simple measure.
The DJ-UBS is composed of futures contracts on physical commodities. The index is designed to minimize concentration in any one commodity or sector. It currently has 19 commodity futures in seven sectors. No one commodity can comprise less than 2% or more than 15% of the index, and no sector can represent more than 33% of the index . The weightings for each commodity included in DJ-AIGCI are calculated in accordance with rules that ensure that the relative proportion of each of the underlying individual commodities reflects its global economic significance and market liquidity. Annual rebalancing and reweighting ensure that diversity is maintained over time.
