Equity Option Premium
Understand Equity Option Premiums
An option premium is the price associated with an option contract. For an option seller, the premium represents the amount received for writing the contract. For an option buyer, it represents the amount paid to obtain the rights associated with the option.
Options premiums are generally quoted on a per-unit basis. Understanding what influences an option premium is an important part of evaluating option contracts and their potential risks.
Three important components that influence an option premium are intrinsic value, time value and implied volatility. Understanding these factors can help market participants evaluate option pricing more effectively.
Intrinsic Value
The relationship between the strike price and underlying market price.
Time Value
The value associated with the remaining time before an option expires.
Implied Volatility
A market-based measure that influences the extrinsic value of an option.
Components of an Option Premium
Intrinsic Value
Represents the value an option may have based on the current relationship between the underlying asset and strike price.
Time Value
Time remaining until expiration can influence the amount market participants are willing to pay for an option.
Implied Volatility
Changes in expected market volatility can influence an option's premium.
Intrinsic Value
The intrinsic value of an option contract is generally based on the difference between the strike price and the current market price of the underlying stock, where applicable.
For a call option, an option can be considered in-the-money when the underlying market price is above the strike price. For a put option, the relationship is reversed.
The further an option moves in-the-money, the greater its intrinsic value can become, subject to the terms and characteristics of the contract.
Time Value
The time value of an option is associated with the amount of time remaining before expiration. Generally, an option with more time remaining may have greater time value than an otherwise comparable option approaching expiration.
As an option approaches its expiration date, its time value generally declines. At expiration, the option's remaining value depends on its applicable intrinsic value and contract terms.
Implied Volatility
Implied volatility is derived from an option's market price and reflects the market's assessment of potential future price variability of the underlying asset.
Changes in implied volatility can affect the extrinsic portion of an option premium. The effect can differ depending on whether a market participant is holding a long or short option position.
