Given the following information calculate the standard deviation of returns of a portfolio that combines government bonds with the market portfolio.
Rm = .11
Rf = .05
Standard Deviation of market return = 0.14
Enter your answer as a decimal accurate to three decimal places.
Proportion invested in Rm = 0.5
See here,
The risk of government bonds is zero because government will not defaults. So, standard deviation of bonds =0.
Portfolio standard deviation =SQRT((weight of market*standard deviation of market)^2+(weight of bonds*standard deviation of bond)^2)
Here they gave proportion invested in market=0.5
So proportion invested in bond =1-weight of market=1-0.5=0.5
Give risk of market=0.14
Standard deviation of portfolio =sqrt((0.5*0.14)^2+(0.5*0)^2)
Portfolio standard deviation =0.070 or 7%
