need to calculate the monthly returns of the portfolio before we can calculate standard deviation. That means we first need to get the prices of each ETF over a certain time period, convert prices to the monthly returns for each ETF, and convert those individual returns to portfolio r...
The premise of standard deviation is a statistical method that gauges the distribution of a set of numbers relative to its means. Often standard deviation is used in finance and is applied to the rate of returns associated with investments. Standard deviation is very useful in developing investi...
How to calculate the sample standard deviation Step 1: Calculate the average The first thing you need to do to calculate the standard deviation of the sample is to work out the average value. To do this you simply add up all the values in your sample, and divide the answer by the numbe...
the SMLrepresents the market’s risk and returnat a given time and shows the expected returns of individual assets. While the measure of risk in the CML is the standard deviation of returns (total risk), the
The CAL is represented as a line graph. The y-axis is the expected return, and the x-axis is the amount of risk, usually measured by the standard deviation of returns. The line displays the relationship between the risk and expected return of portfolios that combine a risk-free asset with...
