E(Rxy) with 50% X and 50% in Y

Weight of X in the portfolio = W_X = 0.5, Weight of Y in the portfolio = W_Y = 0.5

In 2012

E(Rxy) = W_X*E[R_X] + W_Y*E[R_Y] = 0.5*8 + 0.5*24 = 16%

In 2013

E(Rxy) = W_X*E[R_X] + W_Y*E[R_Y] = 0.5*10 + 0.5*20 = 15%

In 2014

E(Rxy) = W_X*E[R_X] + W_Y*E[R_Y] = 0.5*12 + 0.5*16 = 14%

In 2015

E(Rxy) = W_X*E[R_X] + W_Y*E[R_Y] = 0.5*14 + 0.5*12 = 13%

In 2016

E(Rxy) = W_X*E[R_X] + W_Y*E[R_Y] = 0.5*16 + 0.5*8 = 12%

E(Rxz) with 50% X and 50% in Z

Weight of X in the portfolio = W_X = 0.5, Weight of Z in the portfolio = W_Z = 0.5

In 2012

E(Rxz) = W_X*E[R_X] + W_Z*E[R_Z] = 0.5*8 + 0.5*8 = 8%

In 2013

E(Rxz) = W_X*E[R_X] + W_Z*E[R_Z] = 0.5*10 + 0.5*12 = 11%

In 2014

E(Rxz) = W_X*E[R_X] + W_Z*E[R_Z] = 0.5*12 + 0.5*16 = 14%

In 2015

E(Rxz) = W_X*E[R_X] + W_Z*E[R_Z] = 0.5*14 + 0.5*20 = 17%

In 2016

E(Rxz) = W_X*E[R_X] + W_Z*E[R_Z] = 0.5*16 + 0.5*24 = 20%
