What Does In-the-Money Mean?
An option is in-the-money (ITM) when exercising it immediately would result in a positive payoff. For a call option, this means the stock price is above the strike price, so you could buy the stock at the lower strike price and sell it at the higher market price for an instant profit. For a put option, ITM means the stock price is below the strike price, allowing you to sell the stock at the higher strike price.
The amount by which an option is in-the-money equals its intrinsic value. A call with a $100 strike when the stock trades at $115 is $15 in-the-money, giving it $15 of intrinsic value per share. ITM options are more expensive than ATM or OTM options because of this intrinsic value, but they also provide higher probability of profit and more predictable price behavior.
ITM Formulas
- 1ITM amount = $115 - $100 = $15.00 (15% ITM)
- 2Intrinsic value = $15.00
- 3Time value = $17.00 - $15.00 = $2.00
- 4Exercise value per contract = ($115 - $100) × 100 = $1,500
- 5Net profit if exercised now = $1,500 - ($17.00 × 100) = $1,500 - $1,700 = -$200
- 6Breakeven = $100 + $17.00 = $117.00
- 7Stock must reach $117.00 for the trade to be profitable
Advantages of Trading ITM Options
- Higher Delta: ITM options move more closely with the stock, providing better directional exposure
- Lower time value risk: Less premium at risk from time decay compared to ATM or OTM options
- Higher probability of profit: ITM options have greater than 50% chance of expiring with value
- Stock replacement: Deep ITM options can serve as capital-efficient substitutes for owning shares
- Better for hedging: ITM protective puts provide more immediate protection against downside moves
ITM Options and Early Assignment Risk
| Factor | Higher Risk | Lower Risk |
|---|---|---|
| Time value remaining | Very low time value | Significant time value |
| Upcoming dividends | Ex-dividend date within days | No upcoming dividends |
| Option type | Short ITM calls near ex-div | Long options (you decide) |
| How deep ITM | Deep ITM (Delta > 0.90) | Slightly ITM (Delta 0.55-0.70) |
| Expiration proximity | Last week before expiry | 30+ days remaining |
When to Choose ITM Options
If you sell ITM calls on a dividend-paying stock and the remaining time value is less than the upcoming dividend, early assignment is likely. The call buyer can exercise to capture the dividend. Always check the ex-dividend date before selling ITM calls. Close or roll the position before the ex-date to avoid unexpected assignment.
Most brokers automatically exercise ITM options at expiration if they are $0.01 or more in-the-money (the OCC auto-exercise threshold). If you are long an ITM option and do not want exercise, you must explicitly instruct your broker to not exercise before the cutoff time on expiration day.
