How do you calculate downside deviation?
How do you calculate downside deviation?
Downside deviation measures to what extent an investment falls short of your minimum acceptable return by calculating the negative differences from the MAR, squaring the sums, and dividing by the number of periods, and taking the square root.
How do you calculate downside variance?
The downside variance is the square of the downside potential. To calculate it, we take the subset of returns that are less than the target (or Minimum Acceptable Returns (MAR)) returns and take the differences of those to the target.
How do you calculate downside risk?
We then select negative returns only, as they represent downside deviations, and we square them and sum the squared deviations. The resultant figure is divided by the number of periods under study, then we find the square root of the answer, which gives us the downside risk.
How do you calculate downside risk in Excel?
Example of Sortino Ratio (With Excel Template)
- The average return percentage for 12 months of a company XYZ Ltd is given as follows.
- Solution:
- Downside Risk = √(∑(Square of Negative Excess Returns) / No.
- Average Excess Return = Sum of Excess Return / No of Months.
- Sortino Ratio = Average Excess Return / Downside Risk.
What is downside deviation?
Downside deviation is a measure of downside risk that focuses on returns that fall below a minimum threshold or minimum acceptable return (MAR). It is used in the calculation of the Sortino ratio, a measure of risk-adjusted return.
How is downside risk deviation calculated?
After that, we divide it by the number of observations, 9 in our example, to get about 18.78. Finally, we take the square root of that number to get the downside deviation, which is about 4.33% in this case….Calculation of Downside Deviation.

What is the difference between downside and upside risk?
Investors often compare the potential risks associated with a particular investment to possible rewards. Downside risk is in contrast to upside potential, which is the likelihood that a security’s value will increase.
