My put was assigned early. Now what?

You woke up to 100 shares and less cash, days or weeks before expiry. That is early assignment. It's uncommon, it's not a mistake you made, and the next step is simple.

What is actually happening in your account

Your short put is gone. The cash that was set aside for it is gone too. In its place: 100 shares, bought at the strike.

The premium is still yours. Your cost per share is the strike minus that premium. Nothing about the trade's math changed; it just finished early.

US stock options can be exercised by the buyer any day up to expiry. For a put, early exercise usually means the stock fell well below the strike and the put had almost no time value left. The buyer decided there was nothing to wait for.

It can also cluster around dates: right before a dividend on a stock a put buyer wants to be out of, or in the last week when time value is near zero. Our early assignment guide has the full list.

The numbers (an illustration, not a trade idea)

XYZ was at $50. You sold a 45-day put with a $45 strike for $1.00 and collected $100. Your broker set aside $4,500.

Three weeks in, XYZ dropped to $41. The put traded at about $4.05, almost all real value. Overnight you were assigned.

Now you hold 100 shares at a cost of $44 ($45 − $1.00). At $41 the position shows −$300. The $4,500 of cash became $4,100 of stock plus the $100 you were paid.

That −$300 is the same number you would have at expiry with the stock at $41. Early assignment did not add a loss. It removed the three weeks in which the stock might have climbed back above $45 and let the put expire.

Why it is not an emergency

Three things people fear here, and the truth of each:

• "I lost the chance for the put to expire worthless." Yes. In return you now own the shares at a known cost, and you can start the next step right away.
• "Something went wrong at the broker." No. Assignment is random across sellers of that contract. You were picked. See assignment notification timing for when and how it shows up.
• "I have to do something right now." No. The shares are yours. They do not expire. You have time to think.

This is just the middle of the wheel strategy. The put turned into shares. The next turn is a call.

Selling the call: the next trade, outcome by outcome

Say Monday comes and XYZ is still at $41. You sell a 30-day call with a $45 strike (just above your $44 cost, not below it) for $0.60. You collect $60.

The first row is the one to read twice. The call adds $60. It does not stop the shares from falling. If XYZ drops to $34, you are down $940 with a call on top. Owning the stock is still the risk.

The checklist before Monday's call

Do these in order, and do them before the open:

1. Confirm the shares and the cost. 100 shares, cost $44. Check the broker's statement matches.
2. Check what changed. Did the stock fall on news that changes the company, or on a general market dip? If the reason you wanted it at $45 is gone, the honest move may be to sell the shares, not write a call. See assigned and the stock kept falling.
3. Set the give-up price. The level below which you sell the shares and stop. Write the dollar loss at that level.
4. Check the calendar. No earnings and no ex-dividend date inside the call's expiry unless you have decided to accept them.
5. Pick a strike at or above $44. A strike under your cost locks in a loss if called away. Resist the bigger premium.
6. Wait 30 minutes after the open. Then use a limit order near the mid. Monday mornings are noisy and the first prints are often the worst.

The rule for next time

Early assignment on a put is uncommon, but it is a reminder of what the put is: an offer to buy that can be accepted at any time. Two habits remove the surprise:

• Only sell puts on stocks you would buy at the strike this week, not just at expiry.
• When a short put goes deep in the money with little time value left, expect assignment and plan for it. If you don't want the shares, close the put while you still can. Our guide on managing a short put in the money covers that choice.
