Harbor shares rise from $66 to $68 after earnings. Your $65 call, bought for $4, is now quoted at $3.50 with 59 days still left.
Return to the 60-day call on Harbor Coffee, our fictional coffee business, from options basics. This time, the earnings news arrives one day after purchase. The event and quotes are invented; results exclude fees and taxes.
At that quote, one standard contract shows a $50 loss. The stock went your way. Something else in the option's price moved against you.
The premium has two parts
An option's intrinsic value is the value of exercising it immediately, never less than zero. For a call, subtract the strike from the share price. For a put, subtract the share price from the strike. If the result is negative, use zero.
Time value, also called extrinsic value, is the premium left over after intrinsic value.
For Harbor's call, $66 − $65 = $1 of intrinsic value per share. The remaining $4 − $1 = $3 is time value.
For the same 100-share contract, those pieces are worth $100 and $300. You pay $400 for a right with only $100 of immediate exercise value.
Take a separate $65 put quoted at $3, also with 60 days left. Selling a $66 share for $65 offers no advantage: intrinsic value is zero, so all $3 is time value. A right can have a price before it has any exercise value.
Here, intrinsic value is stock-versus-strike arithmetic. It says nothing about what Harbor's business is worth.
In the money does not mean in profit
Moneyness compares the stock price with the strike. A call is in the money when the stock is above the strike; a put is in the money when it is below. An in-the-money option has positive intrinsic value.
At the money means the stock price equals the strike. Out of the money means it is on the opposite side: below the strike for calls, above it for puts.
For a $65 strike:
| Stock price | Call status | Put status |
|---|---|---|
| $60 | Out of the money | In the money |
| $65 | At the money | At the money |
| $70 | In the money | Out of the money |
Moneyness ignores what you paid. Harbor's call is in the money at both $66 and $68, yet selling at $3.50 would lose money after your $4 purchase.
Its expiration break-even is $65 + $4 = $69. Before expiration, you can profit by selling above your $4 entry price even if the stock has not reached $69.
An out-of-the-money option can still have a premium while time remains. Harbor's $3 put has time to become worth exercising.
Time and uncertainty have a price
More time gives the stock more opportunity to move in your favor, which supports time value. Time decay is the loss of option value caused by time passing, with other inputs unchanged. At expiration, time value is gone.
Time value is not a daily rental charge. Dividing Harbor's $3 by 60 days gives $0.05, but the option does not lose that amount on a fixed daily schedule. The rate of decay changes, and other pricing inputs move too.
Implied volatility is the level of volatility that makes a pricing model match the option's market price. Start with the quoted premium and work backward to the size of price swings the model needs to explain it.
Historical volatility measures past price swings. Implied volatility describes uncertainty priced into the option, without choosing up or down or promising a particular move.
Holding other inputs fixed, higher implied volatility generally raises both call and put values. A wider range of possible moves gives calls more room to benefit from a rise and puts from a fall. In the unfavorable direction, their exercise value has a floor of zero. That uneven trade-off gives uncertainty value.
Compare the same stock, strike and expiration. A higher dollar premium on a different contract proves little. Stock price, strike, remaining time, implied volatility, interest rates and expected dividends all enter option valuation.
After earnings, less uncertainty
Before an earnings release, investors face a scheduled event that could move the stock sharply. That uncertainty can lift implied volatility. Once the news arrives, implied volatility often falls. A sharp drop is called volatility crush.
That drop can leave a call down even while its stock rises. It is not automatic, and a large enough stock move can outweigh it.
Harbor's call has 59 days left after the headline. At $68, its intrinsic value is $68 − $65 = $3. Its $3.50 premium leaves just $0.50 of time value. The intrinsic portion grows, but the time-value portion shrinks by more.
The call gains $2 of intrinsic value and loses $2.50 of time value: $2 − $2.50 = −$0.50 per share. Across 100 shares, the quoted value falls from $400 to $350.
The quotes alone cannot tell you how much of the $2.50 drop came from implied volatility. Time value also changes with the stock's position relative to the strike, and one day passed. Estimating each contribution takes a pricing model. The loss is explained; its causes are only partly known.
In a real sale, the bid-ask spread also matters: the displayed value may differ from the price a buyer will pay. The $50 loss here is measured at the quoted $3.50.
The Greeks offer optional depth on sensitivity to pricing inputs. The next application is covered calls and cash-secured puts, where receiving a premium comes with obligations.
In short
- An option's premium is intrinsic value plus time value.
- In the money describes stock versus strike, not whether you made money.
- Time value reflects uncertainty as well as the calendar, and disappears at expiration.
- Implied volatility comes from option prices; it does not choose a direction.
- A favorable stock move can be outweighed by a bigger loss of time value.
- Implied volatility often falls after earnings, but the drop is not automatic.
