CONTRACT EXPIRATION DATES & OPTIONS SETTLEMENT DATA :

All index options expire on the Saturday after the 3rd Friday of the month of interest, except for the quarter-end months (i.e., March, June, September, and December contracts)… Until not too long ago, the expired options are settled and updated on the Saturday morning after the 3rd Friday of each month, except for those quarter-end months in which expired options are settled and updated on the 3rd Friday of that particular month... Starting sometime in 2005/2006, most online futures and options brokerage firms have the expiration data settled and updated on the 3rd Friday some time (maybe an hour or so) after the regular markets are closed… Most of everything nowadays are pretty automatic except those pit-traded contracts still requiring real persons to trade on the floor…

The settlement prices are based on the markets CLOSING data on the Friday... On the other hand, for those quarter-end months, the settlement prices are based on the markets OPENING data on the Friday... Therefore, for this month of May (a non-quarter-end month), the settlement prices will be based on the CLOSING data of May 18...

[However, SPX Options traded on CBOE are a bit different from the other products traded on CME… The exercise-settlement value is calculated using the OPENING (first) reported sales price in the primary market of each component stock on the Friday before the expiration date…]

Please be reminded that the regular market hours are between 9:30AM and 4:00PM Eastern Time, while the futures and options markets are traded between 9:30AM and 4:15PM Eastern Time… Therefore, SPX (the CASH Index of SP500) is frozen at 4:00PM, while the SP500 Futures Indices are still moving until 4:15PM with an additional 15 minutes of trading… As an example, on today (May 18, 2007, the OE date for the month of May 2007), SPX closed at 4:00PM at 1522.75 (Up +10.00)… On the other hand, SP500 Futures Indices all closed at 4:15PM at 1527.90 (June ’07 Future, Up +12.70), 1542.70 (September ’07 Future, Up +12.80), and 1555.70 (December ’07 Future, Up +13.10), respectively…

It is of paramount importance to note that the SP500 Options settlement data are NOT against the SPX value which is the CASH Index of SP500... Rather, they are based on the nearest quarterly Futures Indices which are quite different from the CASH Index respectively, as listed in the aforementioned example... There are only 4 futures contracts in a year, namely March, June, September, and December futures contracts... However, SP500 Options contracts are available for each month of the year, and their respective settlement data are based on the corresponding underlining quarterly futures contracts... For example, J/F/M Options Contracts are based on March Future Index, A/M/J Options Contracts are based on June Future Index, and so on and so forth... For this month of May, the options exercise-settlement prices are against 1527.90 (June ’07 Future Index) instead of 1522.75 (SPX Index)…
