Extended Listings For Equity, ETF, ETN And Index Weeklys Options
In January 2014 CBOE issued Regulatory Circular RG14-010 re: "Expansion of Number of Expirations Listed in S&P 500 Index Weeklys Options (SPXW)." The circular provides that CBOE will list out and maintain six consecutive SPXW expirations at once, not counting the current expiration.
SPX Weeklys are PM-settled on the last trading day, typically a Friday. As with other PM-settled index options, the exercise-settlement value is calculated using the last (closing) reported sales price in the primary market of each component stock. On the last trading day, trading in expiring SPX Weeklys closes at 3:00 p.m. (Chicago time). All non-expiring SPX Weeklys continue to trade until 3:15 p.m. (Chicago time). For standard PM-settled, S&P 500 options that expire on 3rd Fridays, see ticker SPXPM.
Weeklys are listed each week except that no new Weeklys are listed that would expire during the expiration week for regular options (the third Friday of each month), nor would they be listed if they would expire on the same date as a Quarterly option on the same underlying. Other than SPX Weeklys, closing times for Weeklys options match the closing times for regular, non-weeklys on the same underlying.
