Relationship between intrinsic value and time

Price of Options - Extrinsic & Intrinsic Value

relationship between intrinsic value and time

An option's premium is comprised of two values: intrinsic value and time value. For in the money options, intrinsic value is calculated as the difference of the. Extrinsic or time value is one of the two; the other being Intrinsic value. The difference between the strike price (fixed) and the stock price. The two components of an option premium are the intrinsic value and time value of the option. The intrinsic value is the difference between the underlying's price.

It's possible, of course, for an options contract to have no intrinsic value. If a call option has a strike price that is higher than the current price of the underlying security, then there would be no profit to be made from exercising the option at that point and because of this there is no intrinsic value.

The same would be true for a put option that had a strike price lower than the current price of the underlying security. In such circumstances, the contract is said to be out of the money. When the strike price of an options contract is equal to the price of the underlying security, the contract is said to be at the money. Calculating intrinsic value is really quite simple. For call options, you subtract the strike price from the current price of the underlying security.

For put options, you subtract the current price of the underlying security from the strike price. Intrinsic value cannot be a negative number though.

If there is no intrinsic value, then the intrinsic value is considered to be zero. All in the money contracts have intrinsic value, while at the money contracts and out of the money contracts do not.

Extrinsic Value The extrinsic value of an options contract is the less tangible part of the price. It's determined by factors other than the price of the underlying security and can also be known as premium value or time value.

It's essentially the part of the price that accounts for the risk being taken by the writer of the option. Extrinsic value is basically the true cost of owning an option, because any intrinsic value that you pay for is already reflected in the current theoretical profit of the contract.

The reason extrinsic value is sometimes known as time value is because one of the main factors which affect the extrinsic value of an options contract is the time left until it expires. Generally speaking, the extrinsic value will be higher when there is more time left. As a contract moves toward the expiration date, the extrinsic value will typically decrease due to time decay, and there's less time for the price of the underlying security to move.

How to Calculate the Intrinsic Value & Time Value of a Call Option

Time value isn't a particularly accurate label for extrinsic value though, because there are more factors involved than just the time element.

To truly understand extrinsic value, you need to understand how pricing models, such as the Black Scholes Model, work and aid in Options Trading. However, when you are just getting started with options trading, it's sufficient to understand just the basic principles.

Mainly the fact that it represents the true cost of owning an option and serves as compensation to the writer of the contract for the risk they are taking. Accurately calculating extrinsic value can be quite complicated, and again you really need to understand options pricing models, but there is actually a relatively simple way to work out how much you are paying in extrinsic value for any options contract you buy.

As we have mentioned above, any options contracts that are either at the money or out of the money have no intrinsic value.

Therefore, the price of any at the money option or out of the money is made up entirely of extrinsic value. For an in the money contract, the extrinsic value can be determined simply by deducting the intrinsic value from the price. In the picture to the right, we can see how the intrinsic value in red and extrinsic value in blue add together to form the option's total value.

If the strike price is below the current stock price you will be able to buy stock for less than it is currently worth. Like puts, if a call option has no intrinsic value at expiration out of the moneyit will expire worthless. How did we get that number? Then what is the extrinsic value? The easiest way to think about extrinsic value is this: As an equation, it looks like: In the example to the right, the equations would be: So why on earth would anyone pay more for an option than what it could be exercised for?

Another way to understand extrinsic value is this: The amount of time left until expiration and the volatility of the underlying we will look at these briefly in the next sectiondirectly impact the price of an option, thus impacting the extrinsic value. Options cost significantly less money than buying stock outright because options have expiration dates, while stocks do not.

As stated before, traders are hoping that the options price will change in their favor. Essentially, the market is aware the price may change so added premium extrinsic value is included to compensate for the changes in time value and volatility.

The more time an option has until expiration, the more time the underlying price has to change. Thus, the more time the option has until expiration, the more valuable the option becomes. Implied Volatility Aside from time value, implied volatility also makes up the extrinsic value of an option. Implied volatility effectively measures how much the stock price may swing over a specific timeframe.

If volatility in an underlying decreases, the extrinsic value of the option will also decrease. If an option has a longer contract or higher implied volatility, the extrinsic value of the option will increase.

You can see this in the option chain pictured above comparing options with the same strike price, but with longer or shorter timeframes. Would you like to test yourself on the options knowledge you just picked up?
