X has an expected rate of return of 0.14 and variance of 0.01, and Y has an expected rate of return of 0.10 and a variance of 0.0081. The coefficient of correlation, rho, between X and Y is 0.45. What is the SR for the portfolio P? What is the change in SR if the coefficient of correlation is changed to -0.20? Assume TB rate is 5%
