CME Expands GSCI Product Line with Launch of New GSCI Excess Return Futures

Tue Jul 26 2005

CHICAGO, July 26, 2005 - CME, the largest U.S. futures exchange, today announced that it will launch a second futures contract based on the Goldman Sachs Commodity Index (GSCI). The CME GSCI Excess Return Futures Contract will trade exclusively on the CME® Globex® electronic trading platform. The GSCI Excess Return Index differs from the GSCI Spot Index in that it incorporates the returns of the Index as well as the discount or premium obtained by “rolling” hypothetical positions in such contracts as they approach delivery. It also differs in that it is a long-dated contract, about 5 years from initial listing, while the GSCI Spot Index futures contracts have a monthly listing and expiration schedule.
