Rogers International Commodity Index
The Rogers International Commodity Index (RICI) was developed by Jim Rogers on July 31, 1998 to be an effective measure of worldwide raw materials price action. It is a broad-based representation of commodities intended to be global and diverse. 
It is a composite, U.S. dollar-based, total return index. The RICI® represents the value of a basket of commodities consumed in the global economy, ranging from agricultural to energy to metal products. The value of this basket is tracked via futures contracts on 36 different exchange-traded physical commodities, quoted in four currencies, listed on eleven exchanges in five countries.
