A Simple Model of Robust Portfolio Selection
AbstractWe propose a single-period portfolio selection model which allows the decision maker to easily deal with uncertainty about the distribution of asset returns. The model is preference-based and relies upon a separate parametrization of risk aversion and ambiguity aversion. A particular specification of preferences allows us to solve the portfolio selection problem and obtain a simple closed-form expression for the portfolio weights, which lends itself to a straightforward economic interpretation.
