Closing against letting it expire
Letting a short option expire worthless costs nothing and keeps the entire credit. Buying it back costs whatever it still trades for, plus commission. The only thing you get for the money is an early end to the risk, so the decision is the price of the buyback against the damage the remaining days could still do.
Most of the time this is not a close question. The interesting part is where it becomes one.
The two columns
Monday October 13. UBER is $71.80 and your $72.50 call has four days left. It trades at $0.67, all of it time value, because the stock is still under the strike.
- Let it expire: costs nothing. You keep the $153 credit if the stock stays below $72.50, and you carry four more days of the stock being able to do whatever it likes.
- Buy it back: costs $67, plus commission. Call the commission $0.65 a contract, which is roughly the going rate and is an assumption of this example rather than a claim about any particular broker. Total $67.65.
So closing hands back 44 percent of the credit to remove four days. Put that way it sounds obviously bad. Hold that thought.
What it costs at different prices
| UBER | Cost to close | Share of the $153 credit |
|---|---|---|
| $70.50 | $28 | 18% |
| $71.80 | $67 | 44% |
| $73.00 | $126 | 83% |
The price of an exit rises exactly as fast as your reason for wanting one. That is not bad luck, it is what an option is: the closer the stock gets to hurting you, the more the contract that hurts you is worth.
How it actually turned out
UBER closed Friday at $72.49, one cent out of the money, and opened Monday the 20th at $71.10. Three ways of having played it.
| Decision | Premium kept | Stock or proceeds | Total |
|---|---|---|---|
| Closed Monday at $0.67 | $86 | 100 shares, $7,110 | $7,196 |
| Held, not assigned | $153 | 100 shares, $7,110 | $7,263 |
| Held, assigned | $153 | $7,250 cash | $7,403 |
Paying $67.65 for safety was the worst of the three, by $67 against the branch it was protecting you from.
That is one path, and it is the path where nothing went wrong. Push UBER to $78 by Friday instead and the ledger inverts: holding loses $397 on the capped shares, and the $67.65 exit looks like the cheapest decision of the month. Closing early is insurance. On the days you do not need it, it is money you spent for nothing, and most days you do not need it.
The case where it is not close
Pennies. A contract trading at $0.03 costs $3 to close, plus commission, and removes every remaining scenario in which it costs you anything.
Three cents of remaining credit against an unbounded tail is a terrible bargain to keep holding. The stock does not know your option is nearly worthless, and a takeover bid over the weekend cares nothing for the fact that you had 97 percent of the premium banked. Take the $3.65 exit.
Some brokers waive the commission entirely on buying back a short option below a small threshold, which makes the decision even easier. Check yours.
The rule that survives contact
Compare what is left to collect against what you could still lose, and be honest that the second number has no ceiling.
- A few cents of time value left: close it. The remaining income is a rounding error and the tail is not.
- Meaningful time value, stock well away from the strike: let it run. You are being paid to carry a risk that is currently remote.
- Meaningful time value, stock near the strike: this is the real decision, and it is about whether you want the shares, not about the premium. Rolling is the third option and often the right one.
- The buyback costs more than the credit: you are not choosing whether to take a profit, you are choosing whether to realise a loss. Different question, different page: when not to roll.
What does not survive is "never pay to close a winner". It is a fine slogan for the 90 percent of trades that drift to zero, and it is exactly wrong on the ones that do not.
OptionsKing scores every candidate strike on a deterministic 0 to 100 scale, blends that score with the return on the capital the trade ties up, and shows you the highest-ranked handful. There is no minimum score. How it works covers what the ranking does and does not tell you.
Questions people actually ask
Is it better to let an option expire or buy it back?
Letting it expire keeps the whole credit and costs nothing, so it wins whenever the remaining risk is genuinely small. Buying it back is worth paying for when the contract still carries real risk, or when a few cents of remaining premium is all that stands between you and an open-ended tail.
Do I pay a commission if my option expires worthless?
Generally no. Expiration costs nothing at most brokers, while closing the position costs a per-contract commission. That asymmetry is the entire argument for letting cheap contracts run, and it is smaller than most people think.
When should I buy back a short option for a few cents?
Almost always. Three cents of remaining credit is not worth carrying a weekend of gap risk, and the buyback cost is trivial against the position size. Several brokers waive the commission on closing trades below a small price.
Does closing early hurt my returns?
On the paths where nothing goes wrong, yes. On the worked example, closing four days early cost $67 against simply holding. The payment buys certainty, and certainty only pays for itself on the trades that were going to go badly.
