CHICAGO, March 15, 2012 -- CBOE Holdings, Inc. (Nasdaq: CBOE) today announced that trading in SPXpm options at the C2 Options Exchange (C2) reached a new high of 38,225 contracts on Wednesday, March 14. Yesterday's volume more than doubled the previous high of 18,965 contracts on November 17, 2011.

C2's SPXpm product is an all-electronic, cash-settled index option based on the S&P 500 Index, the premier benchmark of the broader U.S. market. SPXpm is similar in structure to CBOE's flagship S&P 500 SPX contract, the most actively-traded U.S. index options product, except it has a "p.m." settlement - the settlement convention found in the OTC market. SPXpm also features European exercise, which eliminates the risk of early assignment.
