Option Pricing Models
Intrinsic Value
- Intrinsic value is the value any given option would have if it were exercised today. Basically, the intrinsic value is the amount by which the strike price of an option is profitable or in-the-money as compared to the stock's price in the market. If the strike price of the option is not profitable as compared to the price of the stock, the option is said to be out-of-the-money. If the strike price i…
Time Value
- Since options contracts have a finite amount of time before they expire, the amount of time remaining has a monetary value associated with it—called time value. It is directly related to how much time an option has until it expires, as well as the volatility, or fluctuations, in the stock's price. The more time an option has until it expires, the greater the chance it will end up in the mo…
Volatility
- An option's time value is also highly dependent on the volatility the market expects the stock to display up to expiration. Typically, stocks with high volatility have a higher probability for the option to be profitable or in-the-money by expiry. As a result, the time value—as a component of the option's premium—is typically higher to compensate for the increased chance that the stock'…
Examples of How Options Are Priced
- Below, you can see the GE example already discussed. It shows the trading price of GE, several strike prices, and the intrinsic and time values for the call and put options. At the time of this writing, General Electric was considered a stock with low volatility and had a beta of 0.49 for this example. The table below contains the pricing for both calls and puts that are expiring in one mo…
How Gamma Works
- Gamma is the options Greek that shows how much the delta will change with a $1.00 movement in the underlying security. Where delta shows how much an option price will increase with the next $1.00 move in a stock, gamma measures how fastthe delta of that option price will increase after that $1.00 move in the stock. Let's take a look at a hypothetic...

Time Value and Volatility
- The rate at which a stock's price fluctuates, called volatility, also plays a role in the probability of an option expiring in the money. Implied volatility, also known as vega, can inflate the option premium if traders expect volatility. Implied volatility is a measure of the market's view of the probability of stock's price changing in value. High volatility increases the chance of a stock mov…
