The amount by which an option is in-the-money. For a call: max(S − K, 0). For a put: max(K − S, 0). The remainder of the premium is extrinsic (time value).
⚡ KEY TAKEAWAY: Intrinsic is the hard floor — an option cannot trade below it without creating arbitrage. Premium sellers harvest extrinsic, not intrinsic.
Why It Matters
Intrinsic value is the hard floor under any option's price. It separates real value (exercise payoff) from speculative value (time premium). Premium sellers need to know the split because they only harvest extrinsic — intrinsic value is untouchable by theta.
How It Works
Call intrinsic = max(S − K, 0). Put intrinsic = max(K − S, 0). If the option is OTM, intrinsic is zero. The option cannot trade below intrinsic without creating a risk-free arbitrage — buy it, exercise immediately, pocket the difference.
Example
NVDA at $142. The $120 call trades at $24.50. Intrinsic = $22.00 (142 − 120). Extrinsic = $2.50. Only $2.50 of the $24.50 is actual time premium. Buying this call is 90% stock substitute, 10% options play.
Common Mistakes
Confusing high premium with high extrinsic. A $30 deep-ITM option might have only $1 of extrinsic — the rest is intrinsic that moves 1:1 with the stock. Also: thinking intrinsic can be negative. The max(…, 0) floor ensures it's always zero or positive.
