New Expected Utility Regret Rule for Optimal Portfolio Choice

A new study introduces the Expected Utility Regret (EUR) rule for portfolio choice, aiming to maximize an investor's expected utility of wealth. This rule is designed to be asymptotically optimal in terms of expected utility regret, which is the difference between an oracle investor's utility and the utility achieved from data-driven portfolio selection. The EUR rule can jointly select a portfolio class and estimate its weights, achieving both minimax and Bayes lower bounds without requiring a prior distribution. The framework encompasses mean-variance and risk-parity portfolios as special cases. AI
