How do you find the standard deviation of an investment?
Standard deviation formula Calculate the variance for each data point by subtracting the mean value from the data point value. Square each resulting variance and add the points together. Divide this from the number of data points minus one. Take the square root of the variance to find standard deviation.
What is the standard deviation of the returns?
It tells how much data can deviate from the historical mean return of the investment. The higher the Standard Deviation, the higher will be the ups and downs in the returns. For example, for a fund with a 15 percent average rate of return and an SD of 5 percent, the return will deviate in the range from 10-20 percent.
How can the return and standard deviation of a portfolio be determined?
Portfolio Standard Deviation is calculated based on the standard deviation of returns of each asset in the portfolio, the proportion of each asset in the overall portfolio i.e., their respective weights in the total portfolio, and also the correlation between each pair of assets in the portfolio.
