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 = 0.12
Enter your answer as a decimal accurate to three decimal places.
Proportion invested in Rm = 0.6
If an investor invests in risk free asset then risk will be zero.
Therefore,
Risk on government bonds (f) = 0
Wm = 0.60
Wf = 0.40
Standard deviation of return of portfolio (p) =
=
=
=
= 7.20 or 0.072
Hence, standard deviation of return of a portfolio (p) is 0.072.
