Intrinsic Value

What Is Intrinsic Value?

Intrinsic value is the immediately realizable value of an in-the-money option — the difference between underlying price and strike price when that difference favors the holder. It’s the portion of premium representing real economic value, independent of time or volatility.

For calls, intrinsic value equals underlying price minus strike price, but only when underlying is above the strike. A call with $150 strike on a stock at $160 has $10 intrinsic value. For puts, intrinsic value equals strike minus underlying when underlying is below the strike. A put with $150 strike on a stock at $140 has $10 intrinsic value.

Options with intrinsic value are in the money. At-the-money or out-of-the-money options have zero intrinsic value — their entire premium is extrinsic. Intrinsic value can never be negative.

Why It Matters for Options Traders

Understanding intrinsic value is fundamental to evaluating fair pricing and making exercise decisions. An option trading below intrinsic value represents theoretical arbitrage — buy the option, exercise it, capture the spread. This enforces a floor: options cannot trade below intrinsic value in liquid markets.

Intrinsic value determines how much premium you can recover regardless of volatility or time. Deep ITM options have high intrinsic value relative to total premium, behaving more like the underlying with less sensitivity to time decay. This is why deep-ITM options work as stock substitutes in leveraged directional trades.

For sellers, intrinsic value sets minimum loss exposure. If you sold a call now $15 in the money, you face at least $15 loss to close, regardless of implied volatility. No amount of theta decay or IV collapse eliminates intrinsic value — only the underlying moving back out of the money removes it.

Key Relationships

• Call intrinsic value: Max(underlying price - strike price, 0) — only positive when stock is above strike.
• Put intrinsic value: Max(strike price - underlying price, 0) — only positive when stock is below strike.
• Zero floor: Intrinsic value cannot go below zero regardless of how far out of the money an option is.
• Extrinsic value: Total premium minus intrinsic value equals extrinsic (time) value — the portion subject to theta decay.
• Deep ITM behavior: Options with high intrinsic value relative to total premium have delta approaching 1.0 and minimal sensitivity to volatility.
• Exercise and assignment: Early exercise of American-style options is sometimes rational when intrinsic value exceeds any remaining extrinsic value.
• Moneyness relationship: Only in-the-money options possess intrinsic value; at-the-money and out-of-the-money options have zero.
