What is the expected standard deviation of portfolio return?
An expected return and a standard deviation are two statistical measures that investors can use to analyze their portfolios. The expected return is the anticipated amount of returns that a portfolio may generate, whereas the standard deviation of a portfolio measures the amount that the returns deviate from its mean.
How do you find standard deviation from expected return?
To find standard deviation on a mutual fund, add up the rates of return for the period you want to measure and divide by the total number of rate data points to find the average return. Further, take each individual data point and subtract your average to find the difference between reality and the average.
What is the formula for the standard deviation of a portfolio?
Formula for Portfolio Variance
The standard deviation of the portfolio variance is given by the square root of the variance. In the calculation of the variance for a portfolio that consists of multiple assets, one should calculate the factor (2𝑤1𝑤2Cov1,2) or (2𝑤1𝑤2ρ𝑖,𝑗σ𝑖σ𝑗)for each pair of assets in the portfolio.
What is a good standard deviation for a stock portfolio?
When using standard deviation to measure risk in the stock market, the underlying assumption is that the majority of price activity follows the pattern of a normal distribution. In a normal distribution, individual values fall within one standard deviation of the mean, above or below, 68% of the time.
How do you calculate expected return variance and standard deviation?
Calculation of expected return, variance, & standard deviation: 2 …
How do you calculate expected return on a portfolio in Excel?
Expected Return for Portfolio = ∑ Weight of Each Stock * Expected Return for Each Stock
- Expected Return for Portfolio = 25% * 10% + 25%* 8% + 25% * 12% + 25% * 16%
- Expected Return for Portfolio = 2.5% + 2% + 3% + 4%
- Expected Return for Portfolio = 11.5%
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.
What does standard deviation of portfolio mean?
Definition: The portfolio standard deviation is the financial measure of investment risk and consistency in investment earnings. In other words, it measures the income variations in investments and the consistency of their returns.
How do you calculate expected return?
Expected return is calculated by multiplying potential outcomes by the odds that they occur and totaling the result.
…
Expected return = (return A x probability A) + (return B x probability B).
- First, determine the probability of each return that might occur.
- Next, determine the expected return for each possible return.
What is a good standard deviation percentage?
The empirical rule, or the 68-95-99.7 rule, tells you where most of the values lie in a normal distribution: Around 68% of values are within 1 standard deviation of the mean. Around 95% of values are within 2 standard deviations of the mean. Around 99.7% of values are within 3 standard deviations of the mean.
How do you calculate expected return and standard deviation of a portfolio?
Standard Deviation of Portfolio = (Weight of Company A * Expected Return of Company A) + ((Weight of Company B * Expected Return of Company B)
- Standard Deviation of Portfolio = (0.50 * 29.92) + (0.50 * 82.36)
- Standard Deviation of Portfolio= 56.14%
How do you calculate the expected return of a portfolio in Excel?

How do you calculate standard deviation of return in Excel?
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.
What does the standard deviation of a portfolio mean?
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.
How do you calculate the expected return of a portfolio?
The basic expected return formula involves multiplying each asset’s weight in the portfolio by its expected return, then adding all those figures together. In other words, a portfolio’s expected return is the weighted average of its individual components’ returns.
What does a high standard deviation of a portfolio mean?
A high portfolio standard deviation highlights that the portfolio risk is high, and return is more volatile in nature and, as such unstable as well.
Is a standard deviation of 5 high?
5 = Very Good, 4 = Good, 3 = Average, 2 = Poor, 1 = Very Poor, The mean score is 2.8 and the standard deviation is 0.54.
What does a standard deviation of 1.5 mean?
In the second graph, the standard deviation is 1.5 points, which, again, means that two-thirds of students scored between 8.5 and 11.5 (plus or minus one standard deviation of the mean), and the vast majority (95 percent) scored between 7 and 13 (two standard deviations).
What is expected return of portfolio?
How do you calculate the expected rate of return on a portfolio?
How do you manually calculate standard deviation in Excel?
Excel standard deviation formula examples
- To get population standard deviation: =STDEVP(B2:B50)
- To calculate sample standard deviation: =STDEV(B2:B10)
How do you use standard deviation formula?
- The standard deviation formula may look confusing, but it will make sense after we break it down.
- Step 1: Find the mean.
- Step 2: For each data point, find the square of its distance to the mean.
- Step 3: Sum the values from Step 2.
- Step 4: Divide by the number of data points.
- Step 5: Take the square root.
What does a standard deviation tell you?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
What is good standard deviation value?
Statisticians have determined that values no greater than plus or minus 2 SD represent measurements that are are closer to the true value than those that fall in the area greater than ± 2SD. Thus, most QC programs require that corrective action be initiated for data points routinely outside of the ±2SD range.
