For instance, if a stock has a mean dollar amount of $40 and a standard deviation of $4, investors can reason with 95% certainty that the following closing amount will range between $32 and $48. In the first histogram, the largest value is 9, while the smallest value is 1. Stocks A and B have the following returns: What are the expected returns of the two stocks?. Hence, the coefficient of variation allows the comparison of different investments. Find the variance of the following test results percentages:. Standard deviation is also a measure of volatility. Question 2 There are two securities with the following parameters: Stock i Expected Return Standard Deviation of i A 15% 40% B 5% 0% a. A possible strategy for testing the model is to collect securities' betas at a particular point in time and to see if these betas can explain the cross-sectional differences in average returns. The average deviation is the measurement of variability but its calculation is exactly the same as the standard deviation. The standard deviation? To calculate the standard deviation, we first need to calculate the variance. The standard deviation is the weighted standard deviation of the riskiest investment only. 1 (30%) Below average 0.

If a data set represents the entire population, the true standard deviation can be calculated as follows: where r i is the ith value of the rate of return on an asset in a data set, ERR is the expected rate of return or the true mean, and N is the size of a population. If your data set is a sample of a population, (rather than an entire population), you should use the slightly modified form of the Standard Deviation, known as the Sample Standard Deviation. If your goal is to create a portfolio with an expected return of 13. or The square root of the variance. If in 1999 investors took the mean historical return and standard deviation of the S&P 500 as proxies for its expected return and standard deviation, then the values of outstanding assets would imply a degree of risk aversion of about A = 3. The larger this dispersion or variability is, the higher the standard deviation. Explanation.
