The Holding Period Return is a measure of the total return received from holding an asset or portfolio of assets over a period of time. It is generally expressed as a percentage.There are many factors that can affect the holding period return, such as the length of time the assets are held, the type of assets involved, and market conditions. In general, however, it is important to remember that the longer an asset is held, the greater its potential return will be. This is why it's often said that "time in the market" is more important than "timing" when it comes to investing success.
