Question 26
Security A has an expected return of 14% and a standard deviation of 20%. Security B has an expected return of 18% and a standard deviation of 25%. Suppose that the rates of return of the two securities have a correlation coefficient of 0.8. Based on the given information select the correct statements from below.
The covariance of security A and security B is 1.5%.
If an investor invests 50% of wealth in each security, then his portfolio’s expected return is 16%.
If an investor invests 50% of wealth in each security, then his portfolio’s standard deviation is 21.36%.
If short selling is not allowed, it is not possible to build a portfolio with expected return of 20%.
