Optimal dynamic portfolio selection: multiperiod mean-variance formulation (Q2707157)

This paper studies quadratic portfolio selection problems in a model with finite discrete time and for assets with independent returns whose mean vectors and covariance matrices are known. It gives explicit feedback formulae (in terms of current wealth) for the optimal strategies under several mean-variance related criteria. This is possible because due to the independence assumption, the associated linear-quadratic control problem can be solved explicitly. The paper also gives necessary optimality conditions for maximizing utility from the mean and variance of final wealth, and concludes with a few numerical examples.
