Moneyness of an option
Moneyness of an option tells you whether the option is in‑the‑money, at‑the‑money or out‑of‑the‑money based on the relationship between the underlying price and the strike price. It is a core concept in the NISM Series VIII exam because it directly influences option premium, Greeks and the payoff diagram. Understanding moneyness helps you answer classification, valuation and risk‑management questions confidently.
Learning Objectives
- 1Define moneyness and its importance in option pricing.
- 2Identify and differentiate ITM, ATM and OTM for both call and put options.
- 3Calculate the moneyness ratio and intrinsic value using standard formulas.
- 4Apply moneyness concepts to typical NISM exam scenarios.
What is Moneyness?
Moneyness is the relationship between the current market price of the underlying asset (S) and the option's strike price (K). It tells you whether exercising the option today would be profitable, break‑even, or result in a loss.
For a call option, the option is in‑the‑money (ITM) when S > K, at‑the‑money (ATM) when S = K, and out‑of‑the‑money (OTM) when S < K. The opposite holds for a put option: ITM when S < K, ATM when S = K, OTM when S > K.
Exam questions often ask you to classify an option given S and K, or to infer the likely premium level. Remember: higher moneyness (deep ITM) generally means a higher premium because the option already possesses intrinsic value.
- ITM options have intrinsic value.
- ATM options have zero intrinsic value but high time value.
- OTM options have no intrinsic value and lower premiums.
Students frequently reverse the ITM/OTM rule for calls and puts. Always recall: for calls, S > K = ITM; for puts, S < K = ITM.
Types of Moneyness
In the NISM syllabus, moneyness is split into three clear categories. Each category influences the option's payoff and its market premium.
In‑the‑Money (ITM): The option would generate a positive cash flow if exercised immediately. For a call, this means the underlying price exceeds the strike; for a put, the underlying price is below the strike.
At‑the‑Money (ATM): The underlying price equals the strike price. The intrinsic value is zero, but the time value is usually at its peak because the market perceives the highest uncertainty about the direction.
Out‑of‑the‑Money (OTM): Exercising the option now would lead to a loss. Calls are OTM when the underlying is below the strike; puts are OTM when the underlying is above the strike. These options have only time value and are cheaper.
Moneyness Classification for Calls and Puts
| Moneyness | Call Condition (S vs K) | Put Condition (S vs K) |
|---|---|---|
| In‑the‑Money (ITM) | S > K | S < K |
| At‑the‑Money (ATM) | S = K | S = K |
| Out‑of‑the‑Money (OTM) | S < K | S > K |
Moneyness Ratio
Where:
S= Current market price of the underlying asset (in rupees)K= Strike price of the option (in rupees)Worked Example
Given S = 12,500 and K = 12,000: Step 1: Compute ratio = 12,500 / 12,000 Step 2: Ratio = 1.042 Verification: 12,500 ÷ 12,000 = 1.042.
The ratio >1 indicates ITM for calls but OTM for puts. Always check the option type before interpreting the ratio.
Intrinsic Value and Moneyness
The intrinsic value represents the immediate exercise profit. It is zero for ATM and OTM options and positive for ITM options.
For a call, intrinsic value = max(0, S – K). For a put, intrinsic value = max(0, K – S). This formula directly ties the concept of moneyness to monetary value.
In the exam, you may be asked to compute the intrinsic value to determine the minimum premium an option can have. Remember that the market premium = intrinsic value + time value.
Where:
S= Underlying price (₹)K= Strike price (₹)Worked Example
Call option: S = 13,000, K = 12,500 Step 1: Compute S - K = 13,000 - 12,500 = 500 Step 2: Intrinsic = max(0, 500) = 500 Verification: max(0, 13,000 - 12,500) = 500. Put option: S = 13,000, K = 13,500 Step 1: Compute K - S = 13,500 - 13,000 = 500 Step 2: Intrinsic = max(0, 500) = 500 Verification: max(0, 13,500 - 13,000) = 500.
Practical Implications for Traders
Traders use moneyness to select contracts that match their market view. Deep‑ITM options behave more like the underlying asset, offering higher delta, while deep‑OTM options have low delta but high leverage.
The Greeks (Delta, Gamma, Theta) vary with moneyness. For example, Delta approaches 1 for deep‑ITM calls and 0 for deep‑OTM calls. Understanding this helps you manage directional risk.
In SEBI‑regulated Indian markets, brokers must disclose the moneyness of options sold to retail clients, ensuring transparency about the risk profile of the product.

NISM‑Style Question
Scenario
Rohit holds a call option on Reliance Industries Ltd. with a strike price of ₹2,500. The current market price of Reliance is ₹2,620. He wants to know whether the option is ITM, ATM or OTM and what its intrinsic value is.
Solution
Step 1: Compare underlying price (S = 2,620) with strike (K = 2,500). Since S > K, the call is In‑the‑Money (ITM). Step 2: Compute intrinsic value using max(0, S‑K) = max(0, 2,620‑2,500) = ₹120. Step 3: Conclude that the option has a minimum premium of ₹120 plus any time value. This classification and intrinsic value calculation are directly asked in the NISM exam.
Conclusion
Rohit's option is ITM with an intrinsic value of ₹120. Remember, ITM status guarantees a positive intrinsic component in the premium.
Key Considerations for SEBI Disclosures
SEBI mandates that brokers disclose the moneyness of options sold to retail investors in the client‑facing statement. This helps investors understand the inherent risk and potential payoff.
The disclosure must specify whether the option is ITM, ATM or OTM at the time of trade, along with the strike and underlying price. Failure to do so can attract penalties under the SEBI (Stock Brokers) Regulations.
For exam preparation, remember the regulatory emphasis on transparency – a question may ask which piece of information is mandatory in a client‑facing document.
C = Call, P = Put, O = OTM. For calls, think "C > K = ITM"; for puts, think "P < K = ITM". This quick mnemonic avoids mixing the rules.
Summary of Moneyness
Moneyness links the underlying price to the strike price, defining whether an option is ITM, ATM or OTM. It determines intrinsic value, influences premium, and affects the Greeks.
Key formulas – the moneyness ratio (S/K) and intrinsic value (max(0, S‑K) for calls, max(0, K‑S) for puts) – are frequently tested in the NISM exam.
Always verify the option type before interpreting ratios or classifications, and remember SEBI’s disclosure requirements for retail clients.
⭐Exam Takeaways
- Moneyness describes the S‑K relationship; ITM, ATM, OTM differ for calls and puts.
- For calls: ITM when S > K, ATM when S = K, OTM when S < K; reverse for puts.
- Moneyness Ratio = S ÷ K; >1 indicates ITM for calls, <1 indicates ITM for puts.
- Intrinsic Value = max(0, S‑K) for calls and max(0, K‑S) for puts; zero for ATM/OTM.
- Higher moneyness (deep‑ITM) leads to higher premium and delta; deep‑OTM offers higher leverage but lower premium.
- SEBI requires brokers to disclose the moneyness of options sold to retail investors.
- Common exam trap: mixing call and put rules – use the "C‑P‑O" mnemonic.
- Remember to calculate both the ratio and intrinsic value when the question asks for option classification and minimum premium.
