Understanding The Basics of Option Prices
Intrinsic Value
- One of the key drivers for an option's premium is the intrinsic value. Intrinsic value is how much of the premium is made up of the price difference between the current stock price and the strike price. For example, let's say an investor owns a call option on a stock that is currently trading at $49 per share. The strike price of the option is $45, and the option premium is $5. Because the s…
Time Value
- The time remaining until an option's expiration has a monetary value associated with it, which is known as time value. The more time that remains before the option's expiry, the more time value is embedded in the option's premium. In other words, time value is the portion of the premium above the intrinsic value that an option buyer pays for the privilege of owning the contract for a c…
The Bottom Line
- An option's value or premium is determined by intrinsic and extrinsic value. Intrinsic value is the moneynessof the option, while extrinsic value has more components. Before booking an options trade, consider the variables in play and have an entry and exit strategy.
Option Pricing Models
The Black-Scholes Formula
- The Black-Scholes model is perhaps the best-known options pricing method. The model's formula is derived by multiplying the stock price by the cumulative standard normal probability distribution function. Thereafter, the net present value (NPV) of the strike price multiplied by the cumulative standard normal distributionis subtracted from the resul...
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.

The table below contains the pricing for both calls and puts that are expiring in one mo…
Stock Option Types

Settlement/Expiration Dates
- Each option has a different expiration date and rule for settlement. There are two option styles in the markets. 1. An American-styleoption which allows the holder of the option to exercise the call/put option any time before expiration 2. A European-styleoption which only allows the option to be exercised on the expiration date. In the past, when the holder of an option exercised his rig…
Example
- Mr. A purchases AAPL November 2016 call options with a strike price of $108. The option contract premium costs $223 for one contract of 100 shares. AAPL, at the time of purchase, stood at $109.10. If the option exercised, Mr. A would get 100 AAPL shares at $108 the next trading day. The next day, AAPL opened at $109.20. If Mr. A decided to sell the shares at marke…
