Analyzed Economic Effects

No Monday/Wednesday Listings Before After-Hours Earnings
For qualifying stocks and ETFs, the Exchange will not list Monday or Wednesday Short Term Option Daily Expirations on any day when an Earnings Announcement will occur after the market close. "Earnings Announcement" means official public quarterly or yearly earnings filed with the Securities and Exchange Commission.
Delist or Mark Closing-Only After Post-Close Earnings
If a Monday or Wednesday Short Term Option Daily Expiration is already listed and an Earnings Announcement is made after the listing becomes available for trading, the Exchange will either delist that expiration if there is no open interest, or, if there is open interest, designate that expiration as closing only.
