I’m starting to learn more about option pricing. Can you elaborate on the difference between intrinsic and extrinsic value?
The price you pay for buying (or receive for selling) an option is often referred to as the “premium.” The premium of an option can be divided into two parts: intrinsic and extrinsic value.
Intrinsic Value:
Intrinsic value or IV can be defined as the amount an option is in-the-money. The deeper in-the-money the option, the more IV it possesses. For a call option, the formula to calculate IV is: stock price minus strike price. For a put option, the formula is: strike price minus stock price. Let’s practice calculating IV on stock XYZ, currently trading at $50. Suppose the 45 calls are trading at $7.50. To calculate how much IV is in this call option, we would plug the stock price (50) and strike price (45) into the aforementioned formula: 50-45= 5. Thus the 45 strike call has $5 of intrinsic value. This should be quite intuitive as the option is indeed $5 in-the-money. Now let’s look at a put option by calculating the amount of IV in the 60-strike put, currently trading at $11.75. Once again just plug the stock price (50) and the strike price (60) into the put IV formula: 60-50 =10. There is $10 of intrinsic value in the 60 put because it is $10 in-the-money.
