The wider the dispersion of returns on a stock, the:
higher the standard deviation.
lower the variance.
lower the real rate of return.
lower the expected rate of return.
Dispersion tells about the size of the range of values that a particular variable can take. With large dispersion, a variable can take values in a wider range. Thus deviation from the mean value of the variable increases.
Since standard deviation is the measure of deviation from the mean value, therefore, the standard deviation will increase with an increase in the range of values that a variable can take.
Thus wider the dispersion higher will be the standard deviation.
Hence the first option is correct.
The wider the dispersion of returns on a stock, the: higher the standard deviation. lower the...
The higher the standard deviation of returns on a security, the _____ the expected rate of return and the _____ the risk. 1) higher; lower 2) lower; lower 3) lower; higher 4) You cannot determine anything about the expected rate of return from the standard deviation. 5) higher; higher
Stock X has a 10.0% expected return, a beta coefficient of 0.9, and a 35% standard deviation of expected returns. Stock Y has a 12.0% expected return, a beta coefficient of 1.1, and a 30.0% standard deviation. The risk-free rate is 6%, and the market risk premium is 5%. Calculate each stock's coefficient of variation. Round your answers to two decimal places. Do not round intermediate calculations. CVx = CVy = Which stock is riskier for a diversified investor?

6. Calculating a beta coefficient for a single stock Suppose that the standard deviation of returns for a single stock A IS A = 25%, and the standard deviation of the market return is on = 15%. If the correlation between stock A and the market is PAM - 0.6, then the stock's beta is prns against the market returns will equal the true value of Is it reasonable to expect that the beta value estimated via the regression of...

QUESTION 28 The expected returns, standard deviation, and coefficient variation of Stocks A and B are given below. If you are risk adverse investor, which stock will you buy? | Stocks | Expected Return Std. Deviation Coefficient Variation, CV A 15% 4% 0.27 B 12% 3% 0.25 O Stock A since expected return is higher Stock B since standard deviation is lower O Stock A since coefficient variation is higher Stock B since coefficient variation is lower O Need additional...

true or false: the standard error of estimate of the expected return is higher than the standard deviation of returns.
Stock A has an expected return of 7%, a
standard deviation of expected returns of 35%, a correlation
coefficient with the market of -0.3, and a beta coefficient of
-0.5. Stock B has an expected return of 12% a standard deviation of
returns of 10%, a 0.7 correlation with the market, and a beta
