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 options (part of SPXW) are options that are listed to provide expiration opportunities every week. SPX Weeklys expiring at the end of each week (End of Week – EOW) are typically listed on Thursdays and expire on Fridays. As of February 23, 2016, CBOE began offering Wednesday Weeklys (also part of SPXW), which are typically listed on Tuesdays and expire the following Wednesday. (Note that EOW Weeklys or Wednesday Weeklys are not listed if either would correspond with a currently listed option, i.e. regular 3rd Friday or SPX End of Month – EOM options).
SPX Weeklys are PM-settled on the last trading day, typically a Friday for SPX EOW Weeklys, or a Wednesday for SPX Wednesday Weeklys. 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.
Closing times for most Weeklys options match the closing times for regular, non-weeklys on the same underlying. See link below for exact times.
