E-mini Nasdaq-100 Tuesday and Thursday options will be available starting October 3, 2022, pending regulatory review.

2. What characteristics are shared amongst E-mini Nasdaq-100 European-style options?

E-mini Nasdaq-100 European-style options at CME Group, which by definition can only be exercised on expiration day, prohibit contrarian instructions. Contrarian instructions is the abandonment of in-the-money options or the exercise of out-of-the-money options. At expiration, all in-the-money options are automatically exercised, whereas all out-of-the-money options are automatically abandoned.

Without the possibility of contrarian instruction, both the options buyer and the writer have certainty about respective positions in the underlying futures contract following the expiration of option positions. The writer does not need to wait for assignment notices, which offers a degree of certainty around exercise.

Market participants familiar with the behavior and specification of existing E-mini Nasdaq-100 European-style options can expect a similar profile for these new expiries, which expire on a Tuesday or Thursday.


3. How many new expiries will be available at a given time?

Generally, the two nearest Tuesday and two nearest Thursday E-mini Nasdaq-100 European-style options contract will be available at a given time.

Occasionally, an additional Tuesday or Thursday expiration date may be listed in advance in addition to the one nearest contract to accommodate holidays. More details are provided in question 12.


4. What are the contract codes for E-mini Nasdaq-100 European-style options?

The chart below details contracts codes for differing E-mini NASDAQ-100 European-style option contracts.


5. What are the underlying instruments for E-mini Nasdaq-100 European-style options?

The underlying instrument for all E-mini Nasdaq-100 European-style options is the nearest expiring quarterly E-mini Nasdaq-100 futures contract as of the expiration of the option.


6. What determines whether European-style options are exercisable?

On their expiration day, European-style options will be automatically exercised if the options are determined to be “in-the-money” using a volume-weighted average fixing price calculated by the Exchange at 4:00 p.m. Eastern Time (ET). This fixing price is calculated and disseminated by CME Group daily under the symbol “NQF.”


7. How is the fixing price determined?

The fixing price is the volume-weighted average price of trading in E-mini Nasdaq-100 futures, traded during the 30-second period leading up to 4:00 p.m. ET. Only outright trades of the Nasdaq-100 futures in the corresponding contract month shall be included in the calculation. Spread trades involving the corresponding contract month of the E-mini Nasdaq-100 futures shall be disregarded for the purpose of the fixing calculation.

For example, at expiration, if the volume-weighted average price of the underlying futures contract was determined to be 12,250.01, an E-mini Nasdaq-100 Weekly call option with a strike price of 12,250 would be automatically exercised; the seller of a call option with a strike price of 12,250 would be automatically assigned. As discussed earlier, contrarian instructions are prohibited for these contracts.


8. How does the fixing price and the futures daily settlement price inter-relate with one another?

The E-mini Nasdaq-100 fixing price (NQF) is used to determine exercise and assignment of the expiring option. It has two-decimal digit precision. Any options that are at least 0.01 index point in the money will be exercised.

A futures positions created as a result of the exercise of the options, that is not otherwise offset with other futures positions, will be marked-to-market at the daily settlement price of the underlying futures. The daily settlement price of E-mini Nasdaq-100 Index futures is in increments of 0.25 index point. The daily settlement price of the futures does not factor into the exercise and assignment of the Tuesday and Thursday Weekly options.


9. Does the listing of these new contracts affect the European option listing cycle?

Yes. As of October 3, 2022, all Weekly European-style Nasdaq-100 options will now handle holiday conflicts slightly differently.

End-of-Month European options listings will be unaffected.


10. How is the listing cycle changing?

Prior to October 3, 2022, for Nasdaq-100 options, the Exchange adjusts the options expiration that falls on a scheduled U.S. holiday to the previous trading day, with the exception of Monday options being adjusted to the ensuing Tuesday if the expiration Monday is a holiday. The options are listed using the Monday, Wednesday, and Friday options contract code, notwithstanding the expiration adjustments due to the scheduled holiday.

Starting October 3, 2022, to avoid confusion, Nasdaq-100 options expiration impacted by scheduled U.S. holidays will be listed with the contract code corresponding to the actual day of expiration.

For example, Christmas falls on a Sunday during 2022, and the holiday is observed on Monday December 26. An option with an expiration date of Tuesday, December 27, 2022, will be listed ahead of time to accommodate the holiday, using contract code E4BZ2, instead of the Monday commodity code E4AZ2.

View the CME Group Holiday Hours page for more information.


11. Will any of these changes effect existing contract expiries?

The changes will only apply to newly listed expiries after October 3, 2022.


12. How many different European-style option expiries will be listed at a given time?

Four contracts are available for the following expiry types:

  • Monday weeklies
  • Wednesday weeklies
  • Friday weeklies (weeks 1, 2, and 4)

In addition, four End-of-Month expiries and three Friday Week three expiries are available.

Two Tuesday expiry and two Thursday expiries will be available at a given time under most circumstances. To accommodate holiday coverage, occasionally an additional expiry will be scheduled on a Tuesday or Thursday.


13. How far in advance can traders expect holiday listings available?

Aside from regular listings, traders can expect the following holiday listing availability:

  • A Tuesday expiry will be newly available four weeks in advance to accommodate Monday or Wednesday holidays.
  • A Thursday expiry will be newly available four weeks in advance to accommodate Friday holidays, unless the holiday lands on a third Friday (whereby it would be available months in advance).
  • Monday, Wednesday, and Friday expiries will continue to be available four weeks in advance to accommodate Tuesday or Thursday holidays.

14. When can traders expect new Tuesday or Thursday contract expirations to become available?

The nearest two expiring Tuesday (Thursday) options will be listed at all times. To facilitate position rolling, the next nearest Tuesday (Thursday) expiry will be listed on the last day of trading of the nearest Tuesday (Thursday) option contract.
