In [[finance]], '''holding period return''' (HPR) is the total return on an [[asset]] or [[Portfolio (finance)|portfolio]] over the period during which it was held. It is one of the simplest measures of [[investment performance]].
 
HPR is the percentage by which the value of a portfolio (or asset) has grown for a particular period. It is the sum of [[income]] and [[capital gains]] divided by the initial period value (asset value at the beginning of the period).
 
'''HPR''' = ((Present Value, or face Value, End-Of-Period Value) + (Any Intermediate Gains e.g. Dividends) - (Initial Value))  /(Initial Value)'''
 
<math>HPR_n \ = \ \frac{Income + (P_{n+1} - P_n)}{P_n}</math>
 
==Example==
<!--Where, in this example, is HPR mentioned? Example shortly to be deleted. -->

To the right is an example of a stock investment of '''one share purchased at the beginning of the year for $100'''. At the end of the first quarter the stock price is $98. This is a capital loss. The stock share bought for $100 can only be sold for $98, which is the value of the investment at the end of the first quarter.  The first quarter return is:
 
($98 – $100 + $1) / $100 = -1%
 
Since the final stock price is $99, the annual ROI is:
 
($99 ending price - $100 beginning price + $4 dividends) / $100 beginning price  =  3% ROI.
 
If the final stock price had been $95, the annual ROI would be:
 
($95 ending price - $100 beginning price + $4 dividends) / $100 beginning price = -1% ROI.
 
==Annualizing the holding period return==
===Over multiple years===
To ''annualize'' a holding period return (translate it into percentage per year), then
 
[[AHPR|Annualized HPR]] = (((Present Value, or face Value, End-Of-Period Value) + (Any Intermediate Gains e.g. Dividends) - (Initial Value))  /(Initial Value)) + 1 ) ^ ( 1 / (Years) ) - 1
 
<math>\mathrm{Annualized\, HPR}_{n}=\left(\frac{D+(P_{n+1}-P_{n})}{P_{n}}+1\right)^{\frac{1}{t}}-1</math>
 
t being number of years that have passed. For example, if you have held the item for half a year, year would equal 1/2.
 
===From quarterly holding period returns===
To calculate an annual HPR from four quarterly HPRs:
 
If HPR1 through HPR4 are the holding period returns for four consecutive periods, the annual '''HPR''' is calculated as follows:
 
<math>1+HPR=\left(1+HPR_{1}\right)\left(1+HPR_{2}\right)\left(1+HPR_{3}\right)\left(1+HPR_{4}\right)</math>
