This study addresses the optimal investment problem with corporate bonds. The investment strategy with corporate bonds is derived to maximize the expected logarithmic utility and the constant relative risk aversion utility of terminal wealth. Default intensity is a function of multiple state variables, which follow CIR process. Three types of default correlation are considered: the conditional independent default correlation, the simultaneous default correlation, and the contagion default correlation. Solutions are derived by using the duality approach. A few implications of the optimal strategy are discussed. Unlike the default-free assets, the optimization of the portfolio with defaultable bonds does not bring out the fund separation.
