Determine the expected return and variance for a portfolio composed of 25% of security A and 75% of security B. Portfolio Expected Return = A*r(a) + B*r(b) Portfolio Expected Return = 25%*0.17 + 75%*0.13 = 0.0425+0.0975 = 0.14 =14% Standard Deviation (SD) = sqrt( Variance) = Sqrt(V) SD (A) = Sqrt (0.0169) = 0.13 SD(B) = sqrt(0.0361) = 0.19 Correlation(a,b) = Covariance(a,b) / ( St.Dev.(a)* St.Dev.(b) ) Covariance(a,b) = Correlation(a,b) *( St.Dev.(a)* St.Dev.(b) ) = 0.4*0.13*0.19 = 0.00988 Variance(a,b) = sq(A)*var(a) + sq(B)*var(b) + 2*A*B*cv(a,b) = sqrt(25%)*0.17 + sqrt(75%)*0.13+2*25%*75%*0.00988 ie Var(a,b) = 0.085+0.1126+0.0037 = 0.2013 b. Determine the expected return and variance of a portfolio that contains 78% security A and 22% security B. Is this portfolio superior to that one in (a) above? Portfolio Expected Return = 78%*0.17 + 22%*0.13 = 0.1326+0.0286 = 0.1612=16.12% Variance(a,b) = sq(A)*var(a) + sq(B)*var(b) + 2*A*B*cv(a,b) = sqrt(78%)*0.17+sqrt(22%)*0.13+2*78%*22%*0.00988 = 0.15+0.061+0.0034 = 0.2144 Yes. This Portfolio is superior to the one in (a).
