If the correlation coefficient on a stock is perfectly positively correlated, p = +1.0, is diversification working?Yes or No point

If the correlation coefficient on a stock is perfectly negatively correlated, p = -1.0, is diversification working?Yes or No point

Assume you are the manager of an investment fund worth $25,000,000 which consists of the following five stocks with their beta coefficients.

Stock A$5,000,0000.5 beta

Stock B$6,000,0001.0 beta

Stock C$4,000,0001.4 beta

Stock D$7,000,0002.0 beta

Stock E$3,000,0002.5 beta

If the market's required rate of return is 12%, r_m, and the risk free rate, r_RF, is 4%, what is this fund's required rate of return, r. First calculate the fund's beta below.Then use the SML equation to calculate the fund's required rate of return, r.
