Portfolio Standard Deviation is the standard deviation of the rate of return on an investment portfolio and is used to measure the inherent volatility of an investment.В It measures the investmentвЂ™s risk and helps in analyzing the stability of returns of a portfolio. LetвЂ™s understand the portfolio standard deviation calculation of a three asset portfolio with the help of an example: Apply the values in the above-mentioned to derive the Standard Deviation formula Standard Deviation Formula Standard deviation (SD) is a popular statistical tool represented by the Greek letter 'Пѓ' to measure the variation or dispersion of a set of data values relative to its mean (average), thus interpreting the data's reliability.Correlation can vary in the range of -1 to 1. Find the correlation between the assets in the portfolio (in the above case between the two assets in the portfolio).Find the weight of each asset in the overall portfolio.Find the Standard Deviation of each asset in the portfolio.Portfolio Standard Deviation FormulaДЄssuming a Portfolio comprising of two assets only, the Standard Deviation of a Two Asset Portfolio can be computed using Portfolio Standard Deviation Formula: Portfolio Standard Deviation calculation is a multi-step process and involves the below-mentioned process. How to Calculate Portfolio Standard Deviation? Standard Deviation of Portfolio is important as it helps in analyzing the contribution of an individual asset to the Portfolio Standard Deviation and is impacted by the correlation with other assets in the portfolio and its proportion of weight in the portfolio. ParticularsДЄverage Rate of Return for the Last 3 Years read more, if Raman wishes to avoid excess volatility, he will prefer investment in Fund A compared to Fund B as it offers the same average return with less amount of volatility and more stability of returns. Thus based on his risk appetite Risk Appetite Risk appetite refers to the amount, rate, or percentage of risk that an individual or organization (as determined by the Board of Directors or management) is willing to accept in exchange for its plan, objectives, and innovation. On the other hand, Fund B has a Standard Deviation of 14, which means its return can vary between -2% to 26% (by adding and subtracting 14 from the average return).Assuming that stability of returns is most important for Raman while making this investment and keeping other factors as constant, we can easily see that both funds are having an average rate of return of 12% however Fund A has a Standard Deviation of 8, which means its average return can vary between 4% to 20% (by adding and subtracting eight from the average return).Raman plans to invest a certain amount of money every month in one of the two Funds which he has shortlisted for investment purpose.

Interpretation of Standard Deviation of Portfolio Portfolio Standard Deviation refers to the volatility of the portfolio which is calculated based on three important factors that include the standard deviation of each of the assets present in the total Portfolio, the respective weight of that individual asset in total portfolio and correlation between each pair of assets of the portfolio.
