"In the money" and "out of the money" are two of the first phrases you hear when you start learning options. They get thrown around constantly, and most introductions treat them like obvious vocabulary. But the distinction between ITM and OTM is not just terminology. It determines what your option is worth, how it behaves, and whether you are paying mostly for real value or mostly for hope.
What "in the money" means
An option is in the money when exercising it right now would produce a profit (ignoring the premium you paid).
For a call option, that means the stock price is above the strike price. If you have a $50 call and the stock is at $54, your call is $4 in the money. You could exercise it, buy shares at $50, and they would be worth $54. That $4 difference is the intrinsic value.
For a put option, it is the reverse. The stock price needs to be below the strike price. A $50 put with the stock at $46 is $4 in the money. You could exercise and sell shares at $50 when they are only worth $46.
Being in the money does not automatically mean the trade is profitable. You still paid a premium to buy the option. If you paid $6 for that $50 call and the stock is at $54, the option has $4 of intrinsic value but you are still $2 underwater on the trade. The break-even point is the strike plus the premium for calls, or the strike minus the premium for puts.
What "out of the money" means
An option is out of the money when exercising it would not make sense because there is no intrinsic value.
For a call: stock price is below the strike. A $50 call with the stock at $47 is $3 out of the money. Exercising would mean buying shares at $50 when you could buy them on the open market for $47. Nobody would do that.
For a put: stock price is above the strike. A $50 put with the stock at $53 is $3 out of the money. You would be selling shares at $50 when they are worth $53.
An OTM option still has value before expiration, though. That value is entirely time value — the market's assessment of the probability that the stock could move enough to push the option into the money before the contract expires. This is why an OTM call with 45 days left still costs something. If expiration were today, it would be worth zero. But 45 days is a long time for a stock to move.
At the money: the middle ground
When the stock price is right at or very close to the strike price, the option is at the money. A $50 call with the stock at $50.10 is essentially ATM. These options have the most time value relative to their price, and they are the most sensitive to changes in implied volatility.
ATM options also have a delta near 0.50 (or -0.50 for puts), meaning they move roughly 50 cents for every dollar the stock moves. This is a useful mental model: an ATM option gives you about half the directional exposure of owning the stock.
In practice, perfectly at-the-money options are rare because stock prices are constantly moving. When traders say "ATM," they usually mean the strike closest to where the stock is currently trading.
Why moneyness matters for option pricing
The split between intrinsic value and time value is the most practical reason to care about moneyness.
An ITM option's price has two components. Part of it is intrinsic value — the real, tangible amount the option is worth right now if you exercised it. The rest is time value. A $50 call with the stock at $55 might trade for $7. Of that, $5 is intrinsic and $2 is time value.
An OTM option's price is 100% time value. There is no intrinsic value because exercising now would be pointless. When you buy an OTM option, you are paying entirely for the possibility that things change before expiration. If they don't, you lose everything you paid.
An ATM option typically has the highest time value in dollar terms. This seems counterintuitive until you think about it: the outcome is maximally uncertain. The stock could go either way, so there is the most "option" left in the option.
This breakdown explains something that confuses a lot of beginners: why does my call lose money even though the stock went up? Because you bought an OTM call, the stock went up a little but not enough to overcome the time decay that was eroding the time value portion. The intrinsic value is still zero, and the time value shrank. Net result is a loss even though the stock moved in your direction.
How moneyness affects the Greeks
If you have been introduced to the Greeks, moneyness changes how they behave.
Delta increases as an option moves deeper in the money. A deep ITM call might have a delta of 0.90, meaning it moves almost dollar-for-dollar with the stock. A far OTM call might have a delta of 0.10, barely responding to stock movement. ATM hovers around 0.50.
Theta (time decay) tends to be highest for ATM options. Deep ITM options have less time value to lose, and far OTM options have already lost most of theirs. ATM options are sitting on the most time value, so they feel the most erosion per day.
Gamma (rate of delta change) is also highest at the money. This means ATM options are the most responsive to stock movement, but also the most unstable. A small stock move can shift the delta significantly.
The practical trade-off: ITM vs OTM
This is where the choice actually matters for your trading.
Buying ITM options is more expensive, but you are paying for real value. A deep ITM call acts almost like owning the stock. It moves with the stock, loses less to time decay as a percentage, and has a higher probability of finishing with some value at expiration. The trade-off is that you need more capital up front and your percentage returns are more modest.
Buying OTM options is cheaper, and that is exactly why they are tempting. A $2 OTM call that doubles to $4 is a 100% return. But the probability of that happening is low. Most OTM options expire worthless. You are paying less per contract, but your probability of losing the entire investment is higher.
Here is a concrete example. Stock is at $100.
You buy the $95 call (ITM) for $8. Of that, $5 is intrinsic value and $3 is time value. If the stock goes to $105, your option is worth roughly $11-12. You made $3-4 on an $8 investment, around 40-50%.
You buy the $105 call (OTM) for $2. All time value. If the stock goes to $105, your option might be worth $2-3, maybe break-even. The stock needs to go to $108 or higher for you to make a decent profit. But if it does reach $110, your option could be worth $6-7, a 200-300% gain.
The ITM trade has a higher probability of profit but a lower maximum percentage return. The OTM trade could produce a bigger percentage gain but is more likely to produce a total loss. There is no free lunch here.
A mistake I see constantly
New traders gravitate toward OTM options because they are cheap. A $0.50 call feels like a low-risk bet. "I can only lose fifty bucks." That is technically true, but when you buy twenty of those over a few months, you have spent $1,000 on contracts that mostly expired worthless. Each one felt cheap. The aggregate was not.
The math on OTM options looks exciting on paper. If this stock goes up 10%, I could make 500%. But that "if" is doing an enormous amount of work. The stock needs to move far enough, fast enough, to overcome both the distance to the strike and the time decay eating your premium every day.
I am not saying never buy OTM options. There are legitimate strategies that use them. But if your entire approach is buying cheap OTM calls because they are affordable, you are probably going to lose money over time. The win rate is too low.
When ITM options make more sense
There are specific situations where buying ITM is the better play.
When you have a strong directional view but want to recover some time value if you are wrong. An ITM option has intrinsic value as a buffer. If the stock moves slightly against you, you lose less than with an OTM option that had no intrinsic value to begin with.
When you are substituting for stock ownership. Deep ITM calls (delta around 0.80-0.90) behave very similarly to owning shares but require less capital. Some investors use deep ITM LEAPS calls as a stock replacement strategy.
When time is short. With only a few days to expiration, an OTM option needs a massive move to become profitable. An ITM option already has real value and does not need the stock to do anything dramatic.
When OTM options make more sense
OTM options have their place too.
When you are expressing a view on the direction of a large expected move (like an earnings announcement or FDA decision). If you believe the stock will make a 15-20% move, an OTM call lets you get exposure at a lower cost per contract.
When you are selling options (writing), not buying. Selling OTM options is a popular income strategy. You collect premium and hope the option stays OTM through expiration. The probability favors the seller in this case.
When you are building spreads. Spread strategies often involve buying one strike and selling another. The OTM leg provides a defined risk or a premium offset.
Moneyness changes throughout the trade
This is something beginners sometimes miss. An option does not stay ITM or OTM forever. The stock moves. What was OTM yesterday could be ITM today.
You buy a $55 call when the stock is at $52. Your call is $3 OTM. Three days later, the stock rallies to $57. Now your call is $2 ITM. The character of your position has changed. Delta is higher. Time decay dynamics are different. The option is now partially intrinsic value rather than pure time value.
This transition is why monitoring your options positions is more involved than monitoring a stock position. A stock is just the price. An option is the price relative to the strike, relative to time remaining, relative to volatility. The moneyness dimension adds a layer that stock trading doesn't have.
Quick reference
For call options:
- ITM: stock price is above the strike price
- ATM: stock price is at or near the strike price
- OTM: stock price is below the strike price
For put options (everything is reversed):
- ITM: stock price is below the strike price
- ATM: stock price is at or near the strike price
- OTM: stock price is above the strike price
What to read next
Moneyness is directly tied to the strike price, which is the reference point that determines whether you are ITM, ATM, or OTM. If you have not read that piece yet, it fills in the other half of this concept.
The other variable is the expiration date. An OTM option with 6 months left is a very different proposition from an OTM option with 3 days left, even at the same strike.
CallPutHub covers moneyness through real-world examples that show exactly how an option's behavior changes as it transitions from OTM to ATM to ITM. Seeing the price, delta, and time value shift together through concrete scenarios makes the concept click in a way that definitions alone cannot.
