For example, if we have an S&P 500 call with a strike price of 1,100 (an example we will use to illustrate time value below), and if the underlying stock index at expiration closes at 1,150, the option will have expired 50 points in the money (1,150 - 1,100 = 50).In the case of a put option at the same strike price of 1100 and the underlying asset at 1050, the option at expiration also would be 50 points in the money (1,100 - 1,050 = 50). That is, to be out of the money, the put's strike would be less than the underlying price, and the call's strike would be greater than the underlying price.Finally, both put and call options would be at the money when the underlying asset expires at the strike price.

All other things remaining the same (or no changes in the underlying asset and volatility levels), the longer the time to expiration, the more value the option will have in the form of time value.But this level is also affected by how close to the money the option is.For example, two call options with the same calendar month expiration (both having the same time remaining in the contract life) but different strike prices will have different levels of extrinsic value (time value). [[This is because one will be closer to the money than the other.The table below illustrates this concept and indicates when time value would be higher or lower and whether there will be any intrinsic value (which arises when the option gets in the money) in the price of the option.As the table indicates, deep in-the-money options and deep out-of-the-money options have little time value.

Intrinsic value increases the more in the money the option becomes.And at-the-money options have the maximum level of time value but no intrinsic value.Time value is at its highest level when an option is at the money because the potential for intrinsic value to begin to rise is greatest at this point. In the figure below, we simulate time-value decay using three at-the-money S&P 500 call options, all with the same strikes but different contract expiration dates. Through this presentation, we are making the assumption (for simplification) that implied volatility levels remain unchanged and the underlying asset is stationary.This helps us to isolate the behavior of time value.The importance of time value and time-value decay should thus become much clearer.

Taking our series of S&P 500 call options, all with an at-the-money strike price of 1,100, we can simulate how time value influences an option's price. If we compare the prices of each option at a certain moment in time, each with different expiration dates (February, March, and April), the phenomenon of time-value decay becomes evident.We can witness how the passage of time changes the value of the options.The figure below illustrates the premium for these at-the-money S&P 500 call options with the same strikes. 60 sekunden trading tipps deutsch. With the underlying asset stationary, the February call option has five days remaining until expiry, the March call option has 33 days remaining, and the April call option has 68 days remaining.As the figure below shows, the highest premium is at the 68-day interval (remember prices are from February 8), declining from there as we move to the options that are closer to expiration (33 days and five days).Again, we are simply taking different prices at one point in time for an at-the-option strike (1100), and comparing them.
