What to Do When You’re Assigned

It’s not an emergency. It’s the natural outcome of a put you sold. Here’s how to think about it clearly.

What just happened, mechanically

You sold a cash-secured put. The stock fell below your strike before expiration (or, less commonly, the holder of the long put exercised early). The put holder’s right to sell you 100 shares at the strike has been exercised. In your account:

The cash you had set aside as collateral has been debited.
100 shares per contract have been credited at the strike price.
The original put position is closed.
The premium you collected at the original sale is yours to keep, regardless of what happens next.

Your effective cost basis on the new shares is the strike price minus the premium per share. If you sold a $50 strike put and collected $1.50 of premium, your effective cost basis is $48.50. That is the number that matters for evaluating whether the position is currently in the green or the red.

Don’t panic. You signed up for this.

The most common mistake new options sellers make is treating assignment as an emergency that requires immediate action. It’s not. Assignment is one of two possible outcomes of every cash-secured put you sell, and you should have sized and selected the trade with full awareness of what assignment would look like.

If you’re feeling panic, that’s diagnostic information about the original trade. Either you sold a put at a strike you didn’t actually want to own at, or you sold too many contracts and the position is now bigger than you can comfortably hold, or the underlying business has materially deteriorated since you entered. All three are real possibilities, and each calls for a different response. But none of them justifies a frantic 9:30 AM market order.

The first-24-hours playbook

Step 1: Verify the assignment

Check your account. Confirm the share count, the cost basis shown by the broker, and the cash debit. Sometimes brokers display assignments in unexpected ways — an “average cost basis” might bake in your premium differently than you expect. Most brokers separately report the strike-level basis and the premium-adjusted basis. Know which is which.

Step 2: Re-read your original trade thesis

Pull up the notes you took when you sold the put. (If you didn’t take notes, this is a good moment to start.) What was the case for owning this business at this strike? Is that case still intact?

Step 3: Re-evaluate the underlying with fresh eyes

What has happened to the underlying business between the put sale and now? Quarterly earnings? Management change? Sector rotation? Macro repricing? Has the case for owning the business strengthened, weakened, or stayed the same?

Step 4: Decide which path you’re on

With the underlying re-evaluated, you have three clean paths:

Hold the shares. The thesis is intact, the position is appropriately sized, and you want to own this business at the current price. Do nothing for now. Continue monitoring as you would any equity position.
Start writing covered calls. The thesis is intact and you want the shares working harder. See our article on covered calls for the strike discipline that distinguishes a productive covered-call program from a yield-chasing trap.
Close the position. The thesis is broken, or you’ve realized the original trade was a mistake. Sell the shares and take the loss. The premium you collected reduces the loss but doesn’t fix it. Don’t hold a broken thesis hoping covered-call premium will rescue you. Premium is a small leak from a big bucket.

The most common mistakes

Mistake #1: Selling immediately at any price

Some investors hate seeing the unrealized loss and dump the position into the open. This is bad for two reasons. First, you sold the put because you wanted the stock at the strike — selling the same shares 5% below the strike a day later destroys the entire logic of the trade. Second, the opening cross is rarely the best execution. If you’re going to sell, do it deliberately and during a calm portion of the trading day, not at the bell.

Mistake #2: Refusing to ever sell

The opposite mistake: convincing yourself the original thesis is intact when it isn’t, and holding through indefinite drawdowns while writing increasingly desperate covered calls. Premium income doesn’t repair a broken business. If the thesis is gone, the position should follow.

Mistake #3: Writing covered calls below cost basis

Right after assignment, the stock is often well below your effective cost basis. A common move is to write covered calls at a strike between the current price and the cost basis, “to harvest premium while waiting for recovery.” The trap: if the stock recovers and is called away, you’ve locked in a loss on the equity that exceeds the premium you collected. Now you’ve taken the loss anyway, just in a slower and more emotionally fraught way. Write covered calls at strikes above your cost basis or don’t write them at all.

Mistake #4: Doubling down on the way down

Some investors respond to assignment by selling more puts at lower strikes on the same name — the “averaging in” impulse. This is concentration creep dressed up as conviction. See our piece on position sizing for why this destroys portfolios.

Tax considerations

Assignment has tax implications that vary based on whether the assignment causes a covered-call exit, whether the put qualifies as a wash sale, and how the basis interacts with the premium. We cover the relevant rules in our options tax guide. Briefly: in most cases, assignment is not itself a taxable event — it’s just a basis adjustment. The taxable event happens when you eventually sell the shares.

What good assignment looks like

A successful assignment looks like this: you sold a put on a high-quality business at a strike below your fair value estimate. The stock dropped through the strike and you got assigned. You re-evaluated the business, found the thesis fully intact, and held the position. Over the following months you wrote covered calls at strikes above your cost basis and at or above your fair value estimate, collecting additional premium. Eventually the stock either recovered and was called away at a profit, or you continued holding it as a long-term position because you genuinely wanted to own it.

That’s the system working as designed. Assignment is not failure mode — it’s an expected outcome of a properly constructed cash-secured put on a name you actually want to own.

What to do next

If you have an open assignment right now, run through the first-24-hours playbook above and pick the path that matches your honest re-evaluation of the underlying.

Build the habit of writing trade notes when you sell a put: thesis, strike rationale, target outcome, what would cause you to abandon the position. Future-you will thank present-you when assignment arrives.
