Question 31
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 4%.
If an investor invests half of his wealth in security A and remaining half wealth in security B, then his portfolio’s expected return is 16%.
If an investor invests half of his wealth in security A and remaining half wealth in security B, then his portfolio’s standard deviation is 21.36%.
If an investor wants to build a portfolio with expected rate of return 15%, then he should invest 25% of wealth in security A and remaining 75% wealth in security B.
