Time Value in Options Trading: Explained, Calculated, and Its Impact on Profits

In the dynamic realm of options trading, time value emerges as a critical factor influencing an option’s premium. It stands alongside implied volatility, collectively constituting the extrinsic value of an option.
Options, financial instruments granting the right to buy or sell an asset at a predetermined price, entail a cost known as the premium. This premium comprises two components: intrinsic value and extrinsic value.

The intrinsic value signifies the disparity between the underlying asset’s current price and the option’s strike price. For call options, intrinsic value equals the underlying price minus the strike price; for put options, it’s the strike price minus the underlying price.

An option’s total premium integrates intrinsic and extrinsic values. Extrinsic value, encompassing time value, tends to diminish as an option nears expiration. Notably, an option with a longer duration until expiration typically boasts a higher time value, offering a more extended window for potential profitability.

Expressed as an equation, time value is articulated as:

Option premium−Intrinsic value=Time value+Implied volatility

Consider, for instance, an Alphabet Inc. $950 call option trading at $97. With an intrinsic value of $94, the time value is $3 ($97 – $94).

As a fundamental rule, the time value of an option tends to increase as the expiration date approaches. Investors are willing to pay a premium for an option with more time remaining, anticipating a favorable shift in the underlying asset’s price.

Conversely, with less time remaining, investors become more conservative in their premium payments. Holding or selling an option with residual time value often prevails over immediate exercise, preserving the opportunity for future profitability.

Augmenting the time allocated to an option or elevating implied volatility serves a common purpose: augmenting the likelihood of the option concluding in the money.

No, an option’s premium is influenced by both intrinsic and extrinsic values. Time value is just one component of the extrinsic value.

Time decay, or time-value decay, results in a faster decline of an option’s time value during the second half of its life. This phenomenon is quantified by the option’s theta.

While time value can enhance profitability, it cannot fully compensate for a strike price that significantly diverges from the underlying asset’s market value.
