> Split any option's premium into intrinsic and extrinsic value, tell ITM from OTM for calls and puts, and see what strike choice trades off.

What you'll be able to do: Split premium into intrinsic + extrinsic, classify ITM/ATM/OTM for calls and puts, and explain the trade-offs of strike choice.

## Every price has two parts

A tiny option chain for a $50 stock, 30 days to expiration, IV 30%. Call and put prices per share. The at-the-money row is highlighted.

| Strike | Call | Put |
| --- | --- | --- |
| 45 | 5.22 | 0.22 |
| 50 | 1.72 | 1.72 |
| 55 | 0.30 | 5.30 |

1. The 45 call costs 5.22 with the stock at 50.
2. If you exercised right now, you'd gain 50 − 45 = 5.00. That's the intrinsic value.
3. The other 0.22 is extrinsic value: what people pay for time and for the chance of a bigger move.

> **Key idea:** Premium = intrinsic value + extrinsic value.

## Intrinsic value

Intrinsic value is how far an option is in the money. It can't be negative, because you'd never exercise a right that loses money.

- Call: max(0, stock − strike). A 70 call with the stock at 80 has 10.00.
- Put: max(0, strike − stock). An 85 put with the stock at 80 has 5.00.
- A 90 call with the stock at 80 has 0. You wouldn't buy at 90 what sells for 80.

## Extrinsic value

Extrinsic value pays for two things: time left, and how much the stock might move. It's biggest at the money, where the outcome is least certain. It shrinks to zero by expiration.

*Chart (Extrinsic value (per share) against Stock price, priced with Black-Scholes):* Extrinsic value of the 50 call as the stock moves, with 30 days to expiration and IV 30%. It peaks when the stock is at the strike, at the money, and fades on both sides.

> **Key idea:** The 55 call has no intrinsic value, yet it costs 0.30. That's all extrinsic: the chance the stock gets above 55 in time.

## In, at and out of the money

| Call | Put |
| --- | --- |
| In the money: stock above the strike | In the money: stock below the strike |
| At the money: stock near the strike | At the money: stock near the strike |
| Out of the money: stock below the strike | Out of the money: stock above the strike |

With the stock at 50, the 45 call is in the money by 5.00 and the 45 put is out of the money. Out-of-the-money options have no intrinsic value at all.

> **Watch out:** Common mistake: mixing up puts. A put is a right to sell, so it gains value when the stock is below the strike.

## Choosing a strike is a trade-off

| 45 call, in the money (5.22) | 55 call, out of the money (0.30) |
| --- | --- |
| Costs $522 per contract | Costs $30 per contract |
| Breakeven: 50.22 | Breakeven: 55.30 |
| Stock stays at 50: −$22 | Stock stays at 50: −$30 |
| Stock reaches 60: +$978 | Stock reaches 60: +$470 |
| Moves almost dollar for dollar with the stock | Needs a big move to pay off |

> **Watch out:** Cheaper isn't a better deal. It's cheaper because it's less likely to pay off.

## Worked example: Five options on a $50 stock, 30 days out

*Illustrative numbers, not real quotes.*

Stock at $50. Split each price into intrinsic and extrinsic value:

| Option | Price | Moneyness | Intrinsic | Extrinsic |
| --- | --- | --- | --- | --- |
| 45 call | 5.22 | ITM | 5.00 | 0.22 |
| 50 call | 1.72 | ATM | 0 | 1.72 |
| 55 call | 0.30 | OTM | 0 | 0.30 |
| 45 put | 0.22 | OTM | 0 | 0.22 |
| 55 put | 5.30 | ITM | 5.00 | 0.30 |

- The 45 call: stock 50 − strike 45 = 5.00 intrinsic. The other 0.22 is extrinsic.
- The 55 put: strike 55 − stock 50 = 5.00 intrinsic. The other 0.30 is extrinsic.
- The ATM 50 call has no intrinsic value, yet carries the most extrinsic value, 1.72.

Now the trade-off. Here is each call's P&L per contract at expiration:

| Stock at expiration | 45 call (5.22) | 50 call (1.72) | 55 call (0.30) |
| --- | --- | --- | --- |
| 50 | −$22 | −$172 | −$30 |
| 55 | +$478 | +$328 | −$30 |
| 60 | +$978 | +$828 | +$470 |

- The cheap 55 call loses only $30 when the stock sits still, but it needs the stock past 55.30 to profit.
- The 45 call loses only $22 if the stock stays at 50, because 5.00 of its 5.22 price is intrinsic value that is still there at expiration.
