What happens when call options expire in the money, and how does it affect your portfolio strategy When a call option expires in the money, it’s automatically exercised or assigned leading to real profit or unexpected obligations, depending on your position.
This moment can be both an opportunity and a risk for traders. Failing to manage this correctly could result in lost gains or forced trades. But with the right plan, you can turn ITM expiry into an advantage.
In this guide, vietnam-ustrade will walk you through what happens at expiry, the decisions you need to make, and how to avoid costly mistakes.
1. Key definitions and option fundamentals
what happens when call options expire in the money? A call option allows the buyer to purchase an asset, often a stock, at a set price called the strike price. The buyer pays a fee called a premium for this right. Each option has an expiration date the deadline to use or sell it.
“In the money” means the asset’s price is above the strike price, making the option potentially profitable if exercised. Using our previous example, the $100 strike call is ITM when the stock price is $110.
Below is a quick reference table to clarify key terms:
Strike Price: The price at which the call holder can buy the stock.
Premium: The cost paid to buy the option.
Assignment: The process where the option writer must sell the stock to the holder.
Automatic Exercise: Broker’s action to exercise ITM options at expiration by default.
2. What happens when call options expire in the money?
To fully understand what happens when call options expire in the money, we’ll explore both the holder’s and writer’s perspectives.
2.1 For option holders (buyers)
2.1.1 Automatic exercise mechanics
Most brokers automatically exercise ITM call options at expiration unless instructed otherwise. This means you buy the underlying shares at the strike price. For example, with a $100 strike call when the stock is at $110, you’d pay $100 per share, immediately gaining $10 per share in value.
2.1.2 Manual exercise vs. selling position
Instead of exercising, holders can also sell their call options before expiry to lock in profit without buying shares. Alternatively, you can let the option expire, but this is only wise if it’s out of the money.
2.1.3 Capital requirements and broker practices
Exercising requires sufficient funds to buy the shares. Brokers often notify clients before expiration and may have different rules on deadline and thresholds. Some allow choosing cash settlement alternatives if available. This becomes especially important in cases of what happens when call options expire in the money, where quick action can prevent forced assignments or capital shortfalls.
2.2 For option writers (sellers)
2.2.1 Assignment: What it is and how it’s triggered
When call options expire ITM, writers may be assigned, meaning they must sell the underlying stock at the strike price. Assignment usually happens automatically after expiration.
2.2.2 Covered vs. uncovered calls – Portfolio impacts
Writers with covered calls own the underlying stock, making assignment straightforward. Writers of uncovered (naked) calls may face margin calls or need to buy shares at market price to deliver, which can be risky if prices rise sharply.
During expiry week and especially expiration day, assignment notifications are typically sent by brokers, and timelines are tight. This process varies by broker but usually follows standard industry rules.
3. Required actions and user choices at ITM expiry
When a call option expires in the money, you have to choose what to do next act or let it run.
3.1 What if you don’t want to buy (or sell) shares?
Many retail investors ask what happens when call options expire in the money, but don’t realize they can act early to control outcomes. If you’re a holder but lack funds or don’t want shares, selling the call before expiry is a common choice. Sellers who don’t want to deliver shares can buy back the call to close their position.
3.2 How to unwind or close your ITM call position
Unwinding means offsetting your position by selling or buying back options before expiry. This avoids automatic exercise or assignment. Timing is crucial, so watch broker alerts and deadlines.

3.3 Alerts, deadlines, and auto-exercise thresholds
Many brokers automatically exercise calls with at least $0.01 intrinsic value, but policies vary. Deadlines to notify brokers about your intentions can be as early as the morning of expiration day. For example, popular US brokers notify clients one day prior, while some Vietnamese platforms offer automated reminders.
Understanding what happens when call options expire in the money helps you act within these timelines confidently. Here is a simple action table to guide you:
If You Are a Holder:
– Want shares: Prepare funds, accept automatic exercise.
– Don’t want shares: Sell call before expiry or instruct broker not to exercise (if possible).
If You Are a Writer:
– Want to avoid assignment: Buy back the call before expiry.
– OK with assignment: Prepare to deliver or settle shares.
4. Cash vs. physical settlement of ITM calls
Most stock options settle physically, meaning shares are exchanged. Index options, like SPX, are cash-settled, so no shares change hands. Instead, the difference between the index and strike price is paid in cash.
This table shows the main differences:
Settlement Type: Physical (Stocks) vs. Cash (Indexes)
Example: AAPL options vs. SPX options
Investor Action: Buy/sell shares vs. receive/pay cash difference
Risk: Physical requires capital for shares; cash requires less capital but no ownership.
5. Profit and loss when call options expire ITM
To fully understand what happens when call options expire in the money, you need to know how to calculate your real profit or loss.
5.1 How to calculate your gains or losses
Profit on an ITM call equals the stock price at expiration minus the strike price, minus the premium paid. That’s why calculating your net return is a vital part of analyzing what happens when call options expire in the money. For example, if the stock closes at $110, strike is $100, and premium was $8, the net gain per share is ($110 – $100) – $8 = $2.
5.2 Example profit/loss scenarios
Here are three examples:
| Stock Price at Expiry | Strike Price | Premium Paid | Profit / Loss |
|---|---|---|---|
| $110 | $100 | $8 | +$2 gain |
| $108 | $100 | $9 | –$1 loss |
| $105 | $100 | $6 | –$1 loss |
5.3 Tax/fee implications (disclaimer)
Fees, commissions, and taxes can reduce profits. Tax rules vary by country and personal circumstances. Always consult a qualified tax professional before making decisions that affect your tax liability.
6. Scenario summary table: What happens when call options expire in the money?

7. Risks, tips, and mistakes to avoid when call options expire in the money
When your call options are in the money (ITM) at expiry, the outcome can either be a nice profit or an unexpected problem. To stay in control, you need to understand the common risks, smart tips, and mistakes that many traders make at this stage.
7.1 Common risks you should know
If you don’t manage your positions properly, here’s what can go wrong:
- Unexpected assignment: You might be forced to sell shares if you’re a call writer and didn’t close the position in time.
- Margin calls: If you wrote a call without owning the stock (a naked call), your broker may ask you to deposit more money.
- Low liquidity: Near expiry, it might be harder to buy or sell options quickly or at a good price.
- Auto-exercise of low-value options: Even if your call is just $0.01 ITM, your broker might still exercise it.
- Settlement confusion: Stock options usually require delivering shares, while index options settle in cash.
Other risks include missing broker emails, changes in auto-exercise policies, or reporting wrong tax numbers due to poor tracking.
7.2 Tips to manage ITM options smartly
To avoid problems and keep your strategy on track, here are some helpful tips:
- Track expiry dates carefully: Use a calendar or set alerts on your trading platform.
- Check margin rules early: Don’t wait until the last minute to prepare funds or assets.
- Ask your broker about auto-exercise: Learn their policies and deadlines ahead of time.
- Prefer covered calls: If you already own the stock, assignment is much easier to handle.
- Double-check costs and fees: Don’t forget about premiums, commissions, or taxes.
- Watch after-hours price moves: These can change whether your option finishes ITM or not.
Always plan your exit in advance and stay in touch with your broker to avoid surprises.
7.3 Mistakes to avoid
Even experienced traders sometimes make these common errors:
- Missing the cut-off time to act before expiry.
- Assuming you won’t get assigned just because you’re not paying attention.
- Forgetting to set aside enough cash or stock for exercise or delivery.
- Letting ITM options expire when you don’t want to buy or sell shares.
- Misjudging profit by ignoring the cost of the option or trading fees.
- Failing to report taxes correctly or ignoring local tax rules.
- Thinking all brokers have the same rules they don’t.

8. Common broker, market, and legal/tax variations
Top brokers in the US (like TD Ameritrade, Fidelity) generally follow automatic exercise for ITM calls at $0.01 or more, with clear notifications a day before expiry. Vietnamese brokers may have varying rules and different notification timeframes; checking your broker’s FAQ is essential.
International tax laws vary widely. US investors often pay capital gains taxes on option profits, while Vietnam has different treatments. Links to broker policies and official tax resources can help you stay informed.
For exact auto-exercise thresholds, notification methods, and settlement practices, consult your broker’s official website or customer support. Comparing US and Vietnam brokerage approaches can reveal nuances important to active traders.
Examples include:
- TD Ameritrade: Auto exercise at $0.01 ITM, alerts 1 day before expiry.
- Interactive Brokers: Supports manual exercise instructions up to morning of expiry day.
- Viet Capital Securities: May require earlier exercise notification.
- SSI Securities: Different margin policies for uncovered calls.
