The Bloomberg Commodity Index (BCOM) is a broadly diversified commodity price index distributed by Bloomberg Indexes. The index was originally launched in 1998 as the Dow Jones-AIG Commodity Index (DJ-AIGCI) and renamed to Dow Jones-UBS Commodity Index (DJ-UBSCI) in 2009, when UBS acquired the index from AIG. On July 1, 2014, the index was rebranded under its current name. The BCOM tracks prices of futures contracts on physical commodities on the commodity markets. The index is designed to minimize concentration in any one commodity or sector. It currently has 22 commodity futures in seven sectors. No one commodity can compose less than 2% or more than 15% of the index, and no sector can represent more than 33% of the index (as of the annual weightings of the components). The weightings for each commodity included in BCOM 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. ==See also== *Goldman Sachs Commodities Index *Reuters/Jefferies CRB Index *Rogers International Commodity Index *Standard & Poor's Commodity Index 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bloomberg Commodity Index」の詳細全文を読む スポンサード リンク
