What is Portfolio Standard Deviation?
Portfolio standard deviation is a measure of the dispersion or volatility of returns for a portfolio of assets. It quantifies the extent of variability or risk associated with the portfolio's returns. The standard deviation of a portfolio takes into account both the individual volatilities of the assets within the portfolio and the correlations between them.
In simpler terms, portfolio standard deviation accounts for the volatility of each asset in the portfolio, their respective weights, and the correlation between the returns of the assets. It measures the risk of the portfolio as a whole, considering diversification effects.
To calculate the portfolio standard deviation, you need the standard deviations of the individual assets' returns, their weights in the portfolio, and the correlation coefficients between the returns of each pair of assets in the portfolio. Then, you apply the formula to compute the overall standard deviation of the portfolio.
How to Calculate Portfolio Standard Deviation?
Portfolio Standard Deviation calculator uses Portfolio Standard Deviation = sqrt((Asset Weight 1)^2*Variance of Returns on Assets 1^2+(Asset Weight 2)^2*Variance of Returns on Assets 2^2+2*(Asset Weight 1*Asset Weight 2*Variance of Returns on Assets 1*Variance of Returns on Assets 2*Portfolio Correlation Coefficient)) to calculate the Portfolio Standard Deviation, The Portfolio Standard Deviation formula is defined as a measure of the dispersion or volatility of returns for a portfolio of assets. Portfolio Standard Deviation is denoted by σp symbol.
How to calculate Portfolio Standard Deviation using this online calculator? To use this online calculator for Portfolio Standard Deviation, enter Asset Weight 1 (w1), Variance of Returns on Assets 1 (σ1), Asset Weight 2 (w2), Variance of Returns on Assets 2 (σ2) & Portfolio Correlation Coefficient (p12) and hit the calculate button. Here is how the Portfolio Standard Deviation calculation can be explained with given input values -> 0.381499 = sqrt((0.4)^2*0.37^2+(0.6)^2*0.56^2+2*(0.4*0.6*0.37*0.56*0.108)).
