For risk management purposes, this statistic might be a better measure of downside risk than the average just discussed. Maximum drawdown (MDD) is a measure that tries to summarize the historical DD experience of an investment or portfolio of securities in a single number.

In addition to the current DD, the average DD of an investment is perhaps more informative about the average level of DD the investor can expect from a portfolio or investment Where p max is the historical peak and p t is the current value of the investment or portfolio. In that case, the asset’s current DD t equals Let’s denote the drawdown at time t as DD t.

Having discussed the concept, we now discuss how to calculate it. The shorter this recovery period, the better. The recovery period or ‘ time under water‘ is the time that the investment needed to reach the level of the previous peak again. As such, it is a measure of downside risk. It’s typically expressed as a percentage from the previous peak. In particular, the peak-to-trough or peak-to-valley drawdown is simply the amount of loss incurred since the previous peak. It is the extent to which an investment is below the highest net asset value achieved by that investment. But first we discuss the concept in detail. In the Excel file below we illustrate how we can perform a drawdown calculation for a randomly generated portfolio. It is a measure that, especially in recent years, has become more popular in finance and risk management in particular. Present Value of Growth Opportunities (PVGO)ĭrawdown is a risk measure used in asset management (mainly by hedge fund investors) to evaluate how long it typically takes an investment to recover from a temporary decline its net asset value.
