When investors buy securities (e.g., stocks), they may hold them for months or years before selling them. The duration during which an investor holds on to a particular security is known as the **holding period **and the return over that period is referred to as the **holding period return**. This is typically abbreviated as **HPR**.

## Holding period return calculator

We offer a holding period return calculator that accommodates up to 10 periods (10 months, 10 years, etc.). All you need to do is to enter the return observations for each period. Please note the following:

- If you have, say, 7 return observations, simply leave the fields for Return 8, Return 9, and Return 10 as zero.
- Make sure to enter “net returns” rather than “gross returns”. For example, if the gross return is 120%, then the net return is 20%, so you should enter 20%.
- The result is shown at the bottom, together with the number of (non-zero) return observations you’ve used.

## Holding period return formula

Imagine that you bought a stock for £5/share in September. Afterward, the share price increased to £8 in October but went back down to £5 in November. What is your holding period return (HPR) over this 2-month period?

Intuitively, you know that the result should be zero because you bought the stock for £5 back in September and it is still worth £5 in November. In general, you can calculate the HPR as follows:

where *P _{0}* is the initial price you paid when you bought the stock and

*P*is the final price you received when you sold the stock. So, we have:

_{T}*HPR = £5 / £5 — 1 = 0*

However, this simple formula works ONLY IF there were no dividends and/or stock splits during the holding period. Otherwise, there are two ways of handling such events as explained next.

### Option 1: Use adjusted prices

The first option is to use what we call **adjusted prices**, which account for dividend payments and stock splits. Various data providers such as Yahoo! Finance offer free access to adjusted stock prices. If you’re using adjusted prices, you can still use the same formula for HPR computations:

*HPR = P _{T} / P_{0} — 1 *

Now, *P _{0}* is the

*adjusted*price you paid when you bought the stock and

*P*is the

_{T}*adjusted*price when you sold it.

### Option 2: Compound returns to obtain the holding period return

If you are unable to use adjusted stock prices, you can use the following formula instead.

With this formula, we first compute the return for each period and then compound them to get the result. Note that *∏ *is the product symbol and is telling us to compound gross returns *(1 + R _{t} )* to obtain the

*HPR.*

Going back to our example, the net return for October is £8 / £5 − 1 = 60% and the one for November is £5 / £8 *− *1 = *−*37.5%. Then, we have:

*HPR = (1 + 60%) (1 *− 37.5%) *− 1 = 0*

This is the same result as before.

##### Summary

In the case of adjusted prices, the HPR is simply the return computed using the adjusted purchase price and the adjusted selling price. In the case of raw returns, you have to first compute the gross return for each period (taking into account dividends, etc.) and then compound these returns to obtain the result.
