How do you find the standard deviation of a portfolio?
In order to calculate standard deviation, figure out the mean or the average in the data set. For each of those numbers and square the result. Once that's done, determine the mean of each of those squared differences, then take the square root of that figure. The result is the standard deviation.What is portfolio standard deviation (%)?
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. It measures the investment's risk and helps analyze a portfolio's stability of returns.- Say there's a dataset for a range of weights from a sample of a population. Using the numbers listed in column A, the formula will look like this when applied: =STDEV. S(A2:A10). In return, Excel will provide the standard deviation of the applied data, as well as the average.
