The single index mоdel hаs been used tо estimаte the Security Chаracteristic Lines (SCL) fоr stocks A and B with the following results: RA = 0.03 + 0.6RM + eA; R-squared for stock A = 30% RB = -0.02 + 1.1RM + eB; R-squared for stock B = 75% Market return standard deviation σM=13% where RA is the excess return on Stock A; RB is the excess return on Stock B; RM is the market excess return; eA is the residual on Stock A; eB is the residual on Stock B. (A) Calculate the standard deviations for stock A and stock B. (B) Break down the total variance of Stock A to the systematic variance and unsystematic variance. (C) Calculate the covariance and correlation between stock A and stock B.
