The Options Clearing Corporation Announces Options Trading Volume Surpasses 2006 Annual Record

CHICAGO, October 2, 2007 - The Options Clearing Corporation (OCC) announced today that the total number of options traded for the year reached 2,033,134,720 contracts yesterday, passing the annual volume record set in 2006 of 2,027,847,586 contracts.

With nearly three full months of trading left for the year, the annual volume record was broken on the first day of the fourth quarter of the year. Throughout 2007, OCC has set all new top 10 record volume days. The highest volume day was August 16 when a total of 23,745,650 contracts were traded.

"Recent increases in market volatility create what is traditionally a good climate for the growth of options trading. When added to the already spectacular growth in trading, it shows that investors increasingly understand the value of listed options in any market environment," said Michael Cahill, OCC President and Chief Operating Officer.
