Suppose the expected returns and standard deviations of Stocks A and B are E(RA)= .091,E(RB)=.151,A=.361, and B=.621. a-1. Calculate the expected return of a portfolio that is composed of 36 percent Stock A and 64 percent Stock B when the correlation between the returns on A and B is .51. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) a- Calculate the standard deviation of a portfolio that is composed of 36 percent Stock 2. A and 64 percent Stock B when the correlation between the refurns on A and B is 51.
