Implementing Markowitz's generalized model of optimal portfolio selection using a factor model is a practical alternative to the calculation of the full variance-covariance matrix of security returns. This note investigates whether the efficient frontier of bond returns is sensitive to how a two-factor model is estimated. An analysis of 19 bond categories with different maturities indicates that the efficient fromtiers obtained are sensitive to the choice of estimation method.
