Options Assignment: What to Do When You Get Assigned

Learn what options assignment is, why it happens and what to do step by step when you get assigned. Stop fearing it and turn it into management.

“I got assigned some options and I don’t know what to do.” If you’ve ever sold options, it’s probably happened to you — or it will. Assignment is one of the biggest fears of everyone starting out with options. But that fear comes from not knowing what really happens. When you understand it, it stops being a fear and becomes management.

What is options assignment?

When you sell an option, you take on an obligation. That obligation can be triggered at any time if the other party — the buyer — decides to exercise their right. That’s assignment: the moment your options position transforms into a stock position.

  • If you sold a put, you get assigned the shares. You end up buying the underlying at the strike where you sold that put.
  • If you sold a covered call, your shares get sold. You deliver them at the strike where you opened the call.
  • If you sold a call without shares (naked), you end up short. This is the most dangerous scenario because the potential loss is unlimited.
Spanish regulation and Interactive BrokersIf you’re not a professional investor, in principle the broker shouldn’t let you open naked calls. This is an important protection for retail investors under Spanish regulation.

Why does early assignment happen?

Most stock options are American style, which means the buyer can exercise at any time, not just at expiration. But this isn’t a random event — there’s a logic behind it. Early assignment usually happens for two main reasons:

  • A nearby dividend — if you have sold calls with a strike of $50 but the underlying is already at $60-65 and a dividend is going to be paid soon, it can be worthwhile for the buyer to exercise to collect that dividend.
  • A deep in-the-money option — when the option is very far in the money, the extrinsic value is minimal and it’s more profitable for the buyer to exercise than to keep the option open.

Understanding these incentives is key. If you know when it’s likely to happen, you can get ahead of it and manage it before it does.

What are you going to see in the broker?

No one is going to call to warn you. When most options expire on Friday, what you’ll see is that on Monday, when you open the platform, your position has changed. Where you used to have an options contract, now a stock position appears.

Watch out for marginWhen you get assigned, your margin is going to change. Holding shares requires different collateral than holding options. The first thing to do on Monday morning is check how your available margin looks.

And here’s the key that many people don’t understand: assignment doesn’t mean you’ve automatically lost money. It means your position has transformed. It’s a change of format, not necessarily a loss.

Practical cases: what happens depending on your strategy

Cash Secured Put → You get assigned shares

If you sold a put and get assigned, you now have the shares bought at the strike. If this was your strategy — for example, a Cash Secured Put — there’s no problem here. It was exactly what you were after. Now you can continue with the Wheel Strategy and start selling calls above to keep generating premiums.

Covered Call → Your shares get sold

If you sold a covered call with shares you already had and get assigned, you’ve simply had those shares sold at the strike you chose. In many cases, that was precisely the goal — selling at a price that already seemed good to you. If you weren’t psychologically prepared to let those shares go, that’s where the problem comes, but it’s not a failure of the strategy.

Naked call → You end up short

This is the worst scenario. If you sold a call without owning the shares and get assigned, you end up in a short position. Here you have to act with a very clear head because the potential loss is unlimited. But even in this case, it’s not the end of the world: you close the position by buying the shares and that’s it. What you can’t do is stay paralyzed — you have to act.

The Monday-morning action plan

When you open the platform and see that you’ve been assigned, follow these three steps:

Step 1: Assess your position


Do you have long or short shares?

How many shares and at what price?

How is your available margin?

Step 2: Decide your exit


Close the shares and go back to zero

Keep the shares and hedge with options (sell calls if you’re long)

Structure the exit with options according to your plan and your margin

Step 3: Understand why it happened


Was it because of a dividend you didn’t have under control?

Was the option deep in the money and expected?

Did your plan account for this scenario?

Why do people struggle with assignment?

Most people struggle with assignment for two reasons, and both are avoidable:

  • They didn’t have a plan written down beforehand — this is the most common one. If before opening the trade you haven’t asked yourself “what do I do if I get assigned?”, you’re going to improvise under pressure. And that usually doesn’t end well.
  • They didn’t understand what they were trading — if you don’t know how the mechanics of assignment work, any change in your position feels like an emergency.
Assignment isn’t a mistake — it’s an advantageIf you trade with option-selling strategies, you have to accept that assignment is a dynamic part of the structure of options. What gives you premiums is precisely that you’re taking on obligations. That’s what pays you.

The solution: have a plan before trading

The practical solution to all of this is super simple: have a plan before opening the trade. A plan that accounts for exactly what to do if you get assigned:

  • What happens if I get assigned? → I’ll do A
  • If the price is at such a level? → I do B
  • If the margin moves like this? → I do C

When everything is clear beforehand, assignment stops being a problem and becomes just another step within your usual trading. And when you finally stop fearing it, you start trading options the right way.

Conclusion

Options assignment isn’t the end of the world. It’s simply a transformation of your position: where you had options, now you have shares. If you know why it happens — dividends, deep in-the-money options — you can get ahead of it. If you have a written plan, you can manage it calmly. And if you understand that assignment is a natural part of selling options, you stop seeing it as a risk and start seeing it as what it really is: the reason you collect premiums.
