游大可以解释第二张图怎么理解吗?
Developed in 1957, the Reuters/Jefferies CRB Index is one of the most often cited indicators of overall commodity prices. Originally, the CRB Index was weighted heavily towards agricultural commodities. Since its inception, it has been revised nine times to be more representative of a broader range of commodity prices, particularly energy. This tenth change brings the Reuters/Jefferies CRB in line with the evolution of a rapidly expanding commodity futures market. The RJ/CRB Index continues to offer investors a broad and reliable benchmark for the performance of the commodity sector; it now represents nineteen commodity futures markets, including all five of the ICE primary agricultural products (cocoa, coffee, cotton, FCOJ and sugar).
The previous version of the Reuters CRB will be renamed the “Continuous Commodity Index” and will be made available for trading under the symbol “CI” after the close of business on June 17th. All outstanding open positions in the current Index will be rolled into the new product and trade under the symbol “CR”. The Exchange will continue to list new months for the CCI.
