A Multi-Period Bank Portfolio Management Program

We describe a bank portfolio management program based on the complete Markowitz model, which explicitly treats risk due to unanticipated fluctuations in interest rate. Our program takes into account both inter-temporal and intra-temporal covariance. The major result of this approach is that, for the same expected return, our model yields a portfolio with significantly smaller risk than that determined by an index model. For the same risk level, our method yields a portfolio with higher expected yield.
