The expected return on stock W is 10% and its standard deviation is 15%.

The expected return on stock W is 10% and its standard deviation is 15%. Expected return on stock V is 16% and its standard deviation is 24%. The correlation between returns of W and V is 20%.

a)     calculate expected return and standard deviation of a portfolio that invests 40% in W and 60% in V.

b)    determine the minimum variance combination of W and V and determine its expected return and standard deviation.

c)     If the risk-free rate is 4%, determine the tangency portfolio and derive the capital market line equation.

Expert Solution

Expected return of stock W=E(RW)=10% " " " " V=E(RV)=16%

  Standard deviation of stock W=(SDW)=15% " " " " V=(SDV)=24% Standard deviation of portfolio return measuring portfolio risk=SDp

correlation coefficient between stock W and V=rW V=20%

Proportion of total portfolio value invested in stock W=XW=40%   " "       " " "    " " " " V=XV=60%

expected return on the portfolio=E(Rp)

E(Rp)=XW*E(RW)+XV*E(RV) =0.40*10+0.60*16 =13.6%

SDp= (XW2SDW2+XV2SDV2+2.XW.XV.rWV.SDW.SDV)1/2

=(0.42*152+0.62*242+2*0.4*0.6*0.2*15*24)1/2

=16.67%
