Title: "Evaluating Portfolio Policies: A Duality Approach"
Abstract:
The performance of a given portfolio policy can in principle be
evaluated by comparing its expected utility with that of the
optimal policy. Unfortunately, the optimal policy is usually
not computable in which case a direct comparison is impossible.
In this paper we solve this problem by using the given portfolio
policy to construct an upper bound on the unknown maximum
expected utility. This construction is based on a dual
formulation of the portfolio optimization problem. When the
upper bound is close to the expected utility achieved by the
given portfolio policy, the potential utility loss of this
policy is guaranteed to be small. Our algorithm can be used to
evaluate portfolio policies in models with incomplete markets
and position constraints. We illustrate our methodology by
analyzing the static and myopic policies in markets with return
predictability and constraints on short sales and borrowing.
