Why did the risk team close my position?

In short, it is to eliminate expiration risk

Expiration risk refers to the potential of creating a large, unhedged position in an underlying due to the exercise/assignment process at expiration. If our risk team determines that an account is subject to expiration risk, then the option(s) position may be closed out before market close on the expiration day.

Characteristics of Expiration Risk

The following attributes of exercise/assignment of equity options at expiration create the potential for expiration risk:

  • All long options that are in-the-money by $0.01 or more automatically exercised unless the long option holder submits a "Do Not Exercise" request.
  • All other long options are not exercised unless the long option holder submits an “Exercise by Exception” request*. This primarily affects customers that hold a long options position that expired OTM, but due to after-hours price action, it becomes ITM.
  • Professional traders & market makers have until 4:30 PM CT on expiration to submit “Do Not Exercise” and “Exercise by Exception” requests to the OCC. (tastyworks customers need to submit these instructions to tastyworks by 3:15 PM CT)
  • Exercises & assignments are processed overnight, so if you are assigned on a short option, there is no way to know until after expiration.


*An option is considered ITM/OTM based on the closing price. Additionally, "Exercise by Exception" requests require the account to have enough buying power in order to process an exercise request.


What about defined-risk spreads?

May no longer be defined-risk at expiration

Although defined-risk spreads allow you to know what your theoretical profit or loss will be, expiration day adds another level of complexity. There is no definitive way to know if you will be assigned on a short option(s) positions in your account after the market closes on expiration day. Although a short option(s) position may have expired OTM based on the closing price, after-hours price action can turn an OTM short option into an ITM option. As a result, spreads (verticals, iron condors, etc.) tend to create the most expiration risk. The risk comes from the long options expiring by the time you know whether or not the short option(s) are assigned. In other words, the defined risk position no longer become a defined-risk.


How can I eliminate expiration risk?

The only way to eliminate expiration risk is to close short options before expiration and submit appropriate “Do Not Exercise” and/or “Exercise by Exception” requests for long options.


Examples of Expiration Risk

Long Options and Spreads

Example 1: Long Options

  1. Account deposits $5,000.
  2. Account buys 500 contracts of out-of-the-money SPY calls that are expiring that day for $0.10. (Total cost = $5,000)
  3. The account doesn’t sell the SPY calls before the market closes, they close in-the-money, and the account doesn’t submit a “Do No Exercise” request.
  4. SPY is down $3.00 the following day.

In the situation described above, all of the calls would automatically exercise, and the account would be long 50,000 shares of SPY the following day. If SPY were down $3.00 the next trading day, then the account would lose $150,000.


Example 2: Spreads

  1. Account deposits $10,000.
  2. Account sells 200 at-the-money dollar wide put spreads in SPY that are expiring that day for $0.50. (Buying power reduction = $10,000)
  3. The spreads are out-of-the-money at the end of the day, so the account doesn’t close the position.
  4. SPY is down $3.00 in the extended hours and down $4.00 the following day.

In the situation described above, the short puts will likely be assigned, but there is no way to know for sure until the following day. If the puts were assigned, the account would be long up to 20,000 shares. If SPY was down $4.00 the next trading day, the account would lose $80,000.
