Trading for expiring MGTNW options will close at 4:00 p.m. ET on the expiration date.

Settlement and Exercise

  • MGTN (AM-Settled): MGTN options exercise will result in delivery of cash on the business day following expiration. The exercise-settlement value, MGSET, is calculated using the opening sales price in the primary market of each component security on the expiration date. The exercise-settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.

  • MGTNW (PM-Settled): MGTNW options exercise will result in delivery of cash on the business day following expiration. The exercise-settlement value, MGTN, is the closing value of the Cboe Magnificent 10 Index, calculated using the closing sales price in the primary market of each component security on the expiration date. The exercise-settlement amount is equal to the difference between the exercise-settlement value and the exercise price of the option, multiplied by $100.

Expiration Months

Cboe may list the following:

  • Up to 6 standard monthly expirations

  • Up to 10 MGTN LEAPS® monthly expirations at one time that expire 12 to 180 months from the date of issuance
