2) You manage bond portfolios and are setting up a new portfolio with a “planning horizon” of three years. So you wish to set the duration of this portfolio to a 3-year horizon.
Portfolio is to be formed by using 2 bonds with durations longer than 3-year planning horizon. You are long one bond and short on other. One bond has duration of 7 years. The other bond has duration of nine years.
Solve, algebraically, for weights which you will need to hold in two bonds to set duration of portfolio to the wanted 3 years.
