Options time decay strategies

Most investors and traders new to options markets prefer to buy calls and puts because of their limited risk and unlimited profit potential. Buying puts or calls is typically a way for investors and traders to speculate with only a fraction of their capital. But these straight option buyers miss many of the best features of stock and commodity options - such as the opportunity to turn time-value decay into potential profits.

When they establish a position, option sellers collect time-value premiums, paid by option buyers. Rather than struggling against the ravages of time value , the option seller can benefit from the passage of time, and time-value decay becomes money in the bank even if the underlying is stationary.

For option writers sellers , time-value decay thus becomes an ally instead of a foe. If you have ever sold covered calls against stock positions, you can appreciate the beauty of selling time value. In this article I focus on the importance of time value in the option-pricing equation.

But before turning to a detailed look at the phenomenon of time value and time-value decay, let's review some basic option concepts that will make it easier for you to understand what we mean by time value. Options and Strike Price Depending on where the underlying price is in relation to the option strike price, the option can be in , out or at the money.

Let's look at this relationship while keeping in mind our central focus on time value. When we say an option is at the money , we mean the strike price of the option is equal to the current price of the underlying stock or commodity.

Time Decay - Using Options to Profit from the Passage of Time

When the price of a commodity or stock is the same as the strike price also known as the exercise price it has zero intrinsic value , but it also has the maximum level of time value compared to that of all the other option strike prices for the same month. Figure 1 provides a table of possible positions of the underlying in relationship to an option's strike price. As can be seen in Figure 1 above, when a put option is in the money, the underlying price is less than the option strike price.

For a call option , 'in the money' means that the underlying price is greater than the option strike price.

For out-of-the-money options, the exact reverse applies. 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 strike price and underlying expire at the exact same price.

While we are referring here to the position of the option at expiration, the same rules apply at any time before the options expire. With these basic relationships in mind, let's now take a closer look at time value and the rate of time-value decay represented by theta , from the Greek alphabet. If we leave volatility aside for now, the time-value component of an option, also known as extrinsic value, is a function of two variables: All other things remaining the same i.

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. Figure 2 below illustrates this concept, indicating when time-value would be higher or lower and whether or not there will be any intrinsic value which arises when the option gets in the money in the price of the option.

As Figure 2 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 the greatest right at this point. Learn more in Understanding The Time Value Of Money. This should make the above concepts more tangible.

Through this presentation, we are making the assumption for simplification that implied volatility levels remain unchanged and that the underlying 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. Assume the date is Feb 8.

If we compare the prices of each option at a certain moment in time, each with different expiration dates Feb, 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. With the underlying stationary, the Feb call option has five days remaining until expiry, the Mar call option has 33 days remaining and the Apr call option has 68 days.

As Figure 3 shows, the highest premium is at the day interval remember prices are from Feb 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 , and comparing them. The fewer days remaining translates into less time value. As you can see, the option premium declines from The next level of the premium, a decline of One important dynamic of time value decay is that the rate is not constant.

As expiration nears, the rate of time-value decay theta increases not shown here. This means that the amount of time premium disappearing from the option's price per day gets greater with each passing day. Looking at the exhibit, you can see that at 68 days remaining until expiration, it takes 1.

But at just 33 days remaining until expiration, the time required for a one-dollar loss in premium has fallen to 1. In the last month of the life of an option, theta increases sharply, and the days required for a one-point decline in premium falls very fast. At five days remaining until expiration, the option is losing one point in just less than half a day.

This means that the premium will decline by approximately 2. Of course, the rate increases even more in the final day of trading, which we don't show here. The Bottom Line While there are other pricing dimensions such as delta, gamma, and implied volatility , a look at time-value decay is a good place to start when beginning to understand how options are priced.
