What you will learn in this lesson
- Understand what "moneyness" means for an Option
- Learn the precise definitions of ITM, ATM, and OTM, for both Calls and Puts
- Understand why moneyness differs for Calls vs Puts, at the same strike
- See how moneyness relates to an Option's premium
- Build intuition for reading an Option chain, which we cover in the next module
You now know strike price, premium, and every core Options term. This lesson adds one more essential concept before we move into Calls and Puts individually: moneyness - where a strike price sits relative to the current market price, and why that relationship matters.
What Is “Moneyness”?
Moneyness describes the relationship between an Option’s strike price and the underlying asset’s current market price. Every Option, at any given moment, falls into one of three categories:
- ITM (In-The-Money) - exercising the option right now would be immediately favorable
- ATM (At-The-Money) - the strike is at, or very close to, the current market price
- OTM (Out-of-The-Money) - exercising the option right now would not be favorable
Moneyness for Call Options
For a Call option (the right to buy at the strike):
| Moneyness | Condition | Why |
|---|---|---|
| ITM | Strike price below market price | You could buy at the lower strike, immediately worth more than market |
| ATM | Strike price ≈ market price | Right at the boundary - neither favorable nor unfavorable to exercise |
| OTM | Strike price above market price | Buying at a higher strike than the current market makes no sense right now |
Market Price: ₹1,000
Call Strike ₹950 → ITM (buy at 950, worth more than 1,000)
Call Strike ₹1,000 → ATM (strike ≈ market price)
Call Strike ₹1,050 → OTM (buying at 1,050 when market is 1,000 - no benefit yet)Moneyness for Put Options
For a Put option (the right to sell at the strike), the logic flips:
| Moneyness | Condition | Why |
|---|---|---|
| ITM | Strike price above market price | You could sell at the higher strike, immediately worth more than market |
| ATM | Strike price ≈ market price | Right at the boundary |
| OTM | Strike price below market price | Selling at a lower strike than the current market makes no sense right now |
Market Price: ₹1,000
Put Strike ₹1,050 → ITM (sell at 1,050, worth more than market's 1,000)
Put Strike ₹1,000 → ATM (strike ≈ market price)
Put Strike ₹950 → OTM (selling at 950 when market is 1,000 - no benefit yet)This is the single most important thing to remember from this lesson: ITM/OTM direction is opposite for Calls vs Puts, at the exact same strike price.
Real-Life Example: Same Strike, Opposite Moneyness
Suppose a stock is trading at ₹1,000, and you’re looking at the ₹950 strike:
- The ₹950 Call is ITM (you could buy at ₹950, worth more than the current ₹1,000 market price).
- The ₹950 Put is OTM (selling at ₹950 when the market is ₹1,000 makes no sense right now - you’d rather sell at market price).
Same strike price, same underlying, same moment in time - completely opposite moneyness, simply because Call and Put rights work in opposite directions.
Why Moneyness Matters: Premium and Probability
Moneyness directly relates to two practical things every trader cares about:
- Premium (cost): ITM options generally cost more than OTM options at the same expiry, since they already carry some “real,” immediate value (called intrinsic value, covered fully in Module 12), on top of time value.
- Probability of profit: ITM options generally have a higher probability of expiring profitably than OTM options, though this comes at the cost of paying more upfront.
Neither ITM nor OTM is “better” in an absolute sense - the right choice depends entirely on a trader’s strategy, risk tolerance, and how much they’re willing to pay for a higher probability of success.
Analogy: A Race With a Head Start
Imagine strike prices as different starting positions in a race toward “the finish line” (being profitable at expiry):
- An ITM option starts the race already partway to the finish line - it needs less additional favorable movement to stay ahead.
- An ATM option starts right at the starting line - it needs the market to move meaningfully in its favor to win.
- A deep OTM option starts well behind the starting line - it needs a large, favorable move just to catch up, let alone win.
Naturally, a head start (ITM) costs more to “buy into” than starting from further back (OTM) - which is exactly why premium scales with moneyness the way it does.
Common Beginner Mistakes
- Applying the same ITM/OTM direction to both Calls and Puts. This is, by far, the most common moneyness mistake - remember, the direction flips between Call and Put.
- Assuming OTM options are worthless. They still carry time value until expiry, reflecting the chance of a favorable move.
- Treating moneyness as a fixed label. It changes continuously as the underlying’s price moves - an option can shift between ITM, ATM, and OTM multiple times before expiry.
- Believing ITM options are automatically the “better” choice. They cost more, and “better” depends entirely on strategy and context, not a universal rule.
Practical Tips
- When you look at any Option chain going forward, practice quickly identifying: is this specific strike ITM, ATM, or OTM, for a Call? Then ask the same for the Put at that identical strike - remembering the direction flips.
- Most broker platforms visually highlight ITM strikes on an Option chain (often with shading) - use this as a training aid until identifying moneyness becomes automatic without needing the visual cue.
- Before buying any option, explicitly note its moneyness and consider: am I paying for a higher probability (ITM), a balanced middle ground (ATM), or a cheaper, lower-probability opportunity (OTM)? This framing will directly support the strategy lessons in Module 13.
Practical Exercise
- Pick a stock or index currently trading at a specific price. Write down 3 Call option strikes (one below current price, one at/near current price, one above) and label each as ITM, ATM, or OTM. Then do the same for 3 Put option strikes.
- Open your broker's Options chain for any underlying. Find the strike closest to the current price (ATM), and note the premiums for 2 ITM and 2 OTM strikes on both the Call and Put side. Observe how premium changes as you move away from ATM in each direction.
Mini Quiz
1. What does "moneyness" describe, in the context of Options?
Moneyness describes where a strike price sits relative to the underlying's current market price - classified as ITM, ATM, or OTM.
2. A Call option is "in-the-money" (ITM) when the strike price is...
A Call option is ITM when its strike price is below the current market price - meaning exercising it (buying at the lower strike) would be immediately favorable.
3. A Put option is "in-the-money" (ITM) when the strike price is...
A Put option is ITM when its strike price is above the current market price - meaning exercising it (selling at the higher strike) would be immediately favorable.
4. What does "at-the-money" (ATM) mean?
ATM describes a strike price that is at, or very close to, the current market price of the underlying - neither clearly ITM nor OTM.
5. If Nifty is trading at 24,000, is a Call option with a strike of 24,500 ITM, ATM, or OTM?
A Call option with a strike (24,500) above the current market price (24,000) is OTM - exercising it (buying at a higher price than the current market) would not currently be favorable.
6. For the SAME strike price, can a Call and a Put on the same underlying have different moneyness at the same time?
Because Calls and Puts benefit from opposite price movements, the same strike is typically ITM for one and OTM for the other (with ATM being the point where the classification flips) - this is a key, easy-to-forget distinction.
7. Do OTM options have zero value/premium?
OTM options aren't worthless while time remains before expiry - they retain some premium (time value) reflecting the market's assessment of the probability they could still become profitable. We cover this fully in Module 12.
Frequently Asked Questions
Is an ITM option always more expensive than an OTM option, at the same expiry?
Generally, yes - an ITM option's premium includes intrinsic value (the immediate, "already favorable" value) plus time value, while an OTM option's premium consists only of time value (since it has no intrinsic value yet). We cover intrinsic value and time value in complete detail in Module 12.
Does moneyness stay fixed once you buy an Option, or can it change?
Moneyness can change continuously, since it's based on the underlying's current market price relative to a fixed strike price. An option that starts OTM can become ATM or ITM if the underlying moves favorably, and vice versa - moneyness is a live, moving classification, not a one-time label.
Why would anyone buy a deep OTM option, if it's unlikely to become profitable?
Deep OTM options are typically much cheaper (lower premium) than ITM or ATM options, offering a smaller, capped-risk way to speculate on a large, less likely price move, or to construct specific strategies (covered in Module 13). It's a legitimate approach, but one that requires understanding the lower probability of profit it typically carries.
What's the practical difference between trading an ITM option versus an OTM option?
ITM options typically cost more (higher premium) but have a higher probability of expiring profitably and tend to move more directly (point-for-point) with the underlying's price. OTM options cost less but have a lower probability of expiring profitably, and their premium is more sensitive to time decay and volatility changes - the right choice depends on the trader's specific strategy and risk tolerance.
Is ATM always exactly at the current price, or can it be "close enough"?
In practice, since exchanges only list specific, discrete strike price intervals (not every possible price), the "ATM" strike is typically the one closest to the current market price, rather than an exact match. This is a practical convention, not a rigid rule.
Does moneyness apply the same way to both Call and Put options?
The concept applies to both, but the direction flips: for Calls, ITM means the strike is below the market price; for Puts, ITM means the strike is above the market price. Getting this direction right for each type is one of the most common early points of confusion.
How does moneyness relate to the risk of buying vs selling an Option?
Moneyness affects premium (cost) and probability of profit, but the fundamental buyer-vs-seller risk asymmetry from Lesson 13 (capped loss for buyer, uncapped-style risk for seller) applies regardless of whether the option is ITM, ATM, or OTM at any given moment.
Will I need to identify moneyness manually every time I look at an Option chain?
No - most broker platforms and Option chain tools visually highlight or color-code ITM, ATM, and OTM strikes automatically, making it easy to identify at a glance. Understanding the underlying concept (this lesson) helps you interpret what that visual highlighting actually means.
Can an option be simultaneously ITM for one trader and OTM for another?
No - moneyness is determined purely by the relationship between the strike price and the current market price of the underlying, which is the same for every market participant looking at that same contract at that same moment. It has nothing to do with an individual trader's own entry price or personal profit/loss.
Why does this lesson close out Module 5, right before Modules 6 and 7?
Because moneyness is a concept both Call options (Module 6) and Put options (Module 7) rely on constantly, when discussing strategy selection, risk, and pricing behavior - having it clearly understood now makes both of those modules significantly smoother to follow.
Glossary
Key Takeaways
- Moneyness describes the relationship between an Option's strike price and the underlying's current market price - classified as ITM, ATM, or OTM.
- A Call option is ITM when the strike is below the current price, and OTM when the strike is above it; a Put option is the exact reverse.
- ATM describes a strike at, or very close to, the current market price - the boundary point between ITM and OTM.
- At the same strike price, a Call and a Put typically have opposite moneyness - if one is ITM, the other is typically OTM.
- OTM options aren't worthless while time remains before expiry - they retain time value, reflecting the chance of a favorable move before expiry.
- Moneyness is a live, continuously changing classification based on the underlying's current price - not a fixed label set at the time of purchase.
Conclusion
Moneyness is one of those concepts that feels abstract until you've worked through a few examples - and then becomes second nature almost immediately. With ITM, ATM, and OTM now clear for both Calls and Puts, Module 5 is complete: you understand what Options are, the four basic positions, the full vocabulary, and how to classify any strike relative to the market. Module 6 now takes everything from this module and applies it specifically to Call options - buying and selling - with full worked examples and payoff diagrams.
