Weekday Options Expirations Proposed for Nasdaq ISE
Published Date: 7/15/2025
Notice
Summary
Nasdaq ISE wants to let traders buy and sell options that expire on Mondays and Wednesdays for certain stocks and ETFs, adding more flexibility to the Short Term Option Series Program. This change could mean more trading opportunities and faster moves for investors starting soon. The SEC is reviewing the update and will decide by August 19, 2025.
Analyzed Economic Effects
6 provisions identified: 3 benefits, 1 costs, 2 mixed.
New Monday & Wednesday Option Expiries
You (as an investor or trader) could be able to buy and sell option series that expire on Mondays and Wednesdays for certain large stocks and ETFs. The Exchange proposes allowing up to two Monday expirations and two Wednesday expirations beyond the current week for each qualifying security, in addition to existing Friday expirations.
Projected Change in Strikes and Strike Breaks
Using a sample set of qualifying symbols (e.g., NVDA, TSLA, AAPL, AMZN, AVGO, GOOGL, MSFT, META), the Exchange estimates the expansion would add about 16% more strikes for those symbols and that the marginal increase in strike breaks in 2024 would be 66 total (about 22 on Mondays and 44 on Wednesdays). Weeklies currently comprise 52% of total options volume.
Which Securities Can Get Extra Expiries
The extra Monday and Wednesday expirations would only be allowed for 'Qualifying Securities' that meet specific tests each quarter: for stocks, market capitalization greater than $700 billion (measured on the last day of the prior quarter); for ETFs, Assets Under Management greater than $50 billion by NAV. Other requirements include monthly options volume over 10 million sides, a position limit of at least 250,000 contracts, and participation in the Penny Interval Program.
No Expiries on Post-Close Earnings Days
For Qualifying Securities, the Exchange would not list a Monday or Wednesday expiry on any day when there is an after-market Earnings Announcement filed with the Commission. This means expirations will be skipped on days with official post-close quarterly or yearly earnings filings.
Strike Intervals and P.M. Settlement
The Monday and Wednesday expirations would use the same strike price intervals currently applied for SPY, QQQ, and IWM: $0.50 or greater for strikes below $100, $1 for strikes between $100 and $150, and $2.50 or greater for strikes above $150. These series will be P.M.-settled (settle at the close of business).
Cap on Number of Series Remains
The Exchange would continue to be limited to opening no more than 30 series for each expiration date for a specific option class, and that 30-series restriction would apply to the new Monday and Wednesday expirations as well. The Exchange may also list series already open on other exchanges.
