Monthly/Weekly Summary
All of the options listed on the indexes below are cash-settled. The symbols listed below, except for OEX, are European-style options, meaning they can only be exercised, resulting in an assignment, at expiration. If an expiration day or last trade day falls on an exchange holiday, the expiration day or last trade day will be the prior business day.
Some of the underlyings below may be subject to a Single-Listed Exchange Proprietary Index Options Fee by the CBOE. To learn more about these fees, please click here.
