Expiration and settlement of Micro E-mini S&P 500 and Nasdaq-100 options
How is the expiration price determined for Micro E-mini options?
The special fixing price for these contracts is determined by the volume-weighted average trading price of the underlying E-mini futures during the final 30 seconds of trading before the cash equity markets close. For tracking purposes, this benchmark is designated as ESF for Micro E-mini S&P 500 options and NQF for Micro E-mini Nasdaq-100 options.
What happens when Micro E-mini S&P 500 and Nasdaq-100 options expire?
All contracts within this suite are European-style and financially settled, meaning they auto-exercise at expiration based on the following clearinghouse mechanics:
- Automatic exercise: CME Clearing automatically exercises all in-the-money (ITM) options at maturity.
- Financially settled: Instead of delivering a physical futures contract, long option holders automatically receive the net cash value of the position directly into their account.
- Zero futures exposure: Short option holders are assigned a cash debit rather than an opposing physical futures position. This eliminates the risk of inheriting unexpected, unmanaged overnight exposure to the futures market.
- No early assignment risk: Because these options are European-style, they cannot be exercised prior to maturity, allowing option sellers to hold positions with absolute certainty regarding expiration timing.
Can these options be closed out before expiration?
Yes. Traders are not required to hold contracts until maturity. Both long and short European-style options can be traded out of or liquidated on the Globex platform at any time prior to their scheduled expiration.
