Risk Factors Affecting Option Price

A contract to buy or sell an underlying asset at a given price, often known as the strike price, on or before a certain date is referred to as an option. A call option is a chance to buy, whereas a put option is an opportunity to sell the underlying asset. There are a lot of factors that go into determining an option’s premium. It is difficult to determine the effects of these pricing components without applying complex mathematical models. The amount of time left until the option’s expiration, the interest rate situation, the price and volatility of the underlying asset, and the present market climate are all important considerations.

Underlying Price

Use reasoning in this situation. You would logically pay more for the call when the company is trading close to $280 as opposed to when it is trading at $320, right? For example, if you are considering a call option that enables you to purchase XYZ shares at $280 per share. This is due to the fact that the call option is closer to being in the money. For put options, this works in the opposite manner.

Strike Price

At this price, call owners can buy shares and put owners can sell shares. As in the previous case, wouldn’t you rather pay less for the option to buy shares at, say, $270 than more for the option to buy the stock at $320? Having the option to purchase shares at a discount is always more desirable. As a result, calls increase in price as the strike price decreases. Likewise, as the strike price rises, it puts a gain in value and becomes more costly.

Expiration Periods

It doesn’t take much effort to comprehend how time affects things, but it does take some work to fully appreciate how important the date of expiration might be. Stock traders have the advantage of time since successful firms often enjoy prolonged growth. Time is on their side.

However, time works against the option buyer since the value of the option will fall as days pass with little to no change in the underlying asset. This is because the value of the option will decrease even if the underlying asset does not change. In addition, the value of an option will decrease at a rate that is proportional to the proximity to its expiration date.

On the other hand, this is beneficial for option sellers who want to make money from time decay, particularly in the penultimate month when it happens the quickest when they are trying to maximize their profits.


The hardest concept for beginners to understand is how volatility affects an option’s pricing. It is based on a metric called statistical (or historical) volatility, or SV, which looks at the stock’s previous price movements over a certain time period.

Volatility is the difference between daily stock price changes and is a factor often linked to the Greeks option. This is another term for changes in a stock’s price. More volatile stocks are more frequently susceptible to shifting strike price levels than their non-volatile peers.

Large moves improve the likelihood of generating money. So, compared to less or non-volatile stock options, volatile stock options are much more expensive. It’s crucial to remember that even little adjustments to volatility forecasts can have a big effect on option pricing.

Volatility is typically thought of as an estimate, and using merely an estimate, particularly for future volatility, renders it virtually impossible to determine the ideal option value.

Other Key Factors To Keep In Mind


The pricing of options is influenced by cash dividends since they have an effect on the value of the underlying stock. Because of the expectation that the stock price would drop by the dividend amount on the ex-dividend date, options contracts with significant cash payouts tend to have lower call prices and higher put premiums.

Options Type

The value of an option is determined by the type of option that it is. There are two types of options available to choose from: Options to Call and Options to Put. The distinction allows one to determine which side of the market or transaction they are on at any one time. It’s likely that the typical trader has the finest understanding of this variable.

Interest Rates

Options prices, like those of many other financial assets, are impacted by changes in interest rates and the present rate of interest. Changes in interest rates have the opposite impact on call and put option premiums: increasing rates increase the value of calls while decreasing the value of puts. In contrast, the opposite is evident when interest rates are falling.

Our Final Word

The value of each choice depends heavily on the criteria mentioned above. An investor’s sole say is in the option’s strike price and time remaining before expiration (presuming the underlying securities have already been selected). As a result, business investors need to zero in on the optimal combination of strike price and time to expiry to ensure the best stock trades.
