Intrinsic Value, Extrinsic Value, and Moneyness
The two parts of every option premium: the value an option would have if it were exercised now, and the extra paid for what might still happen. How each behaves as the share price moves and as time runs out.
The short version
An option is in the money when exercising it now would be worth something, at the money when the share price equals the strike, and out of the money otherwise. Its intrinsic value is that exercise value, and never less than zero. Everything else in the premium is extrinsic value, also called time value: the price of the chance that the option will be worth more before it expires. Time value is largest when the share price is near the strike, and it shrinks to nothing by expiration, slowly at first and quickly at the end. An out-of-the-money option is made entirely of it.
By the end of this lesson, you'll be able to
- Classify an option as in, at, or out of the money and calculate its intrinsic value
- Split a premium into intrinsic value and time value
- Describe how time value changes with the share price and as expiration approaches
Why this matters
The option chain in Strike, Expiration, and Premium had a call priced at $10.80 and another at $0.95, on the same share and the same date. Those two premiums are made of different stuff. Most of the first is value that exists today and would survive if nothing else happened. All of the second is a payment for possibility, and possibility has an expiry date. Knowing which part of a premium is which tells a buyer what they'll lose simply by waiting, and tells a seller what they're being paid for.
Moneyness
Moneyness describes where the share price stands against the strike.1
- In the money. A call is in the money when the share price is above its strike. A put is in the money when the share price is below its strike. Exercising would be worth something.
- At the money. The share price equals the strike.
- Out of the money. A call whose strike is above the share price, or a put whose strike is below it. Exercising would be worth nothing.
The same strike is in the money for one kind of option and out of the money for the other. With STU Corp at $50, a $45 call is in the money by $5 and a $45 put is out of the money by $5.
Intrinsic value
Intrinsic value is the amount by which an option is in the money, and an option that's out of the money has an intrinsic value of zero.1 It's what the option would be worth if it expired this instant.2
Call's intrinsic value = Share price − Strike, or zero if that's negative
Put's intrinsic value = Strike − Share price, or zero if that's negative
Intrinsic value can't be negative, because the holder is never obliged to exercise. That one-sidedness is the source of an option's value.
Extrinsic value, or time value
An option almost always costs more than its intrinsic value. The difference is called extrinsic value or, more commonly, time value: whatever the premium is in addition to intrinsic value.1
Time value = Premium − Intrinsic value
Time value is the price of what might happen between now and expiration. A $55 call on a $50 share is worth nothing if exercised today. People still pay $2 for it, because there are three months in which the share might rise above $55. That $2 is entirely time value.
| Strike | Call premium | Intrinsic | Time value | Put premium | Intrinsic | Time value |
|---|---|---|---|---|---|---|
| $40 | $10.80 | $10.00 | $0.80 | $0.45 | $0.00 | $0.45 |
| $45 | $6.85 | $5.00 | $1.85 | $1.50 | $0.00 | $1.50 |
| $50 | $3.90 | $0.00 | $3.90 | $3.40 | $0.00 | $3.40 |
| $55 | $2.00 | $0.00 | $2.00 | $6.50 | $5.00 | $1.50 |
| $60 | $0.95 | $0.00 | $0.95 | $10.35 | $10.00 | $0.35 |
The premiums are the ones from the previous lesson. The calls with strikes below $50 and the puts with strikes above it are in the money.
Read the two time-value columns from top to bottom. Each peaks at the $50 strike and falls away on both sides. The disclosure document gives the rule: an option normally has very little time value if it's substantially in the money, and one that's substantially out of the money has only time value, though less of it than an at-the-money option on the same share and date.1
The reason is uncertainty. At the money, the option is balanced on its edge, and a small move either way decides whether it pays, so the right to wait and see is worth the most. Deep in the money, it will almost certainly be exercised and behaves nearly like the shares. Far out of the money, it almost certainly won't be, and little is paid for a slim chance.
