Understanding the Options Premium
The lower this strike price is in relation to the Big Tech Company’s current price, the higher the premium you’ll have to pay. The Black-Scholes call option formula is calculated by multiplying the stock price by the cumulative standard normal probability distribution function. The net present value (NPV) of the strike price multiplied by the cumulative standard normal distribution is then subtracted from the resulting value of the previous calculation. Black-Scholes posits that instruments such as stock shares or futures contracts will have a lognormal distribution of prices following a random walk with constant drift and volatility. The equation uses this assumption and factors in other important variables to derive the price of a European-style call option.
The Basics of Option Premium: What It Is and How It’s Calculated
Option Greeks, attributes like Delta and Vega that indicate changing market factors, also play a significant role in determining option premiums. This premium can be calculated using models like the Black-Scholes model, the Binomial model, and the Monte Carlo simulation, which consider factors like asset price, strike price, and expiration time. On the other hand, the strike price, a fixed and agreed-upon value, determines the level at which an option holder can buy or sell the underlying asset. As investors navigate these critical elements, understanding their roles in pricing and execution becomes paramount for making informed decisions in trading. For example, consider a call option with a strike price of $50, an underlying stock trading at $60, and an option premium of $12. The option’s intrinsic value would be $10 (the difference between the strike price and the underlying stock price), and the extrinsic value would be $2 (the option premium minus the intrinsic value).

Higher the volatility of the underlying asset, the more expensive it is to buy the option. This table shows the trading price of GE, several strike prices, and the intrinsic and time values for the call and put options. General Electric was considered a stock with low volatility at this time and had a beta of 0.49. option premium formula Historical volatility looks back in time to show how volatile the market has been. This helps options investors determine which exercise price is most appropriate to choose for a particular strategy. Historical volatility (HV) helps determine the possible magnitude of future moves of the underlying stock.

The amount of time remaining on an option impacts its premium or value. Intrinsic value is the portion of an option’s price that’s not lost or impacted due to the passage of time. Many options expire worthless, so accounting for time decay is crucial for avoiding and limiting losses. Adding time to an option or increasing the IV theoretically has the same fundamental effect. They increase the probability that an option will finish in the money (ITM). Options trading is most suitable for more experienced retail investors, particularly those who carefully research their trades and have a predefined strategy.
Asset prices are often observed to have significant right skewness and some degree of kurtosis or fat tails. High-risk downward moves often happen more often in the market than a normal distribution predicts. Similarly, binomial models allow you to break the entire option duration to further refined multiple steps and levels. Using computer programs or spreadsheets, you can work backward one step at a time to get the present value of the desired option.

In either case, an investor’s successful use of option contracts requires an understanding of the option premium, or the amount an investor will pay for the option. Like the call option, an investor uses a put option to lock in a stock price. In this case, the option protects against a decrease in the stock’s market price. Time decay is the decline in the value of an options contract as the expiration date approaches. It is a key factor in the option premium and can have a significant impact on the potential profitability of an options trade.
Options are decaying assets meaning every day that passes the options premiums get cheaper. While this is an important piece to trading directional options, the other factors below can have just as big of an impact on your profitability. The risks of loss from investing in CFDs can be substantial and the value of your investments may fluctuate. CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage.
How far away the stock price is from the strike price of the option is referred to as the” moneyness” of the option. Option premiums are calculated by adding an option’s intrinsic value to its time value. We want to clarify that IG International does not have an official Line account at this time.
An options contract that’s “out of the money” today, could be “in the money” tomorrow if the option market price of the contract’s underlying asset increases. This fact illustrates the time value of an option contract in that an investor may pay above an option’s intrinsic value in anticipation of an increase in the value of the related asset. An option contract is a financial instrument whereby the option’s holder can buy or sell the underlying asset at a certain price during a predetermined period. For instance, a call stock option might grant its owner the right to buy 500 shares at a price of $30 per share at any time between the date the option was created and one year later. An investor uses a call or put option to enhance their investment strategy. For example, consider two call options with the same strike price and expiration date, but with different underlying stocks.
The trinomial model is a “tree” calculator that’s similar to the binomial model. Both involve a certain number of “tree steps” and both calculate options prices. The time value of the option rises when the market believes a stock will be very volatile.
However, understanding the factors that impact the options premiums can help you select the best strategy to maximize your profits based on your outlook for the stock. Intrinsic value is the difference between the option’s strike price and the current price of the underlying market. For call options, intrinsic value is calculated by subtracting the strike price from the underlying price. For put options, the opposite is true – intrinsic value is calculated by subtracting the underlying price from the strike price.
