Index/Benchmark Summary
The Dow Jones® UBS WTI Crude Oil SubindexSM (a sub-index of DJ—UBS Commodity Index) is intended to reflect the crude oil segment of the commodities market. The Index consists of futures contracts on crude oil only. Visit Dow Jones Indexes for more information.
Unlike equities, which entitle the holder to a continuing stake in a corporation, commodity futures contracts specify a delivery date for an underlying physical commodity. The Dow Jones—UBS Commodity Index purchases futures contracts of a commodity, and, as the date for a futures contract comes due, the DJ—UBSCI sells that contract and purchases a new short-term contract with delivery dates a few months out. The Dow Jones—UBS Commodity index thus "rolls" its futures positions, and continually avoids delivery of the physical commodity.
The Dow Jones—UBS Commodity Index is valued using the settlement prices for the underlying futures contracts. The DJ—UBSCI rolls its contracts over the course of 5 consecutive business days, starting on the 6th business day of the month. Each day, 20% of each futures position that is included in the month’s roll is rolled. Not all contracts are rolled every month.
