Synopsis:
Many studies show that mean-variance portfolios perform poorly, delivering suboptimal average out-of-sample utility. A lesser-known fact we characterize is that their out-of-sample utility is also very volatile. Using our analytical characterization of performance volatility, we propose a robustness measure that balances out-of-sample utility mean and volatility and show that neither mean-variance portfolios nor minimum-variance portfolios offer maximal robust performance. Our robustness measure serves as a portfolio framework to construct strategies that achieve the optimal tradeoff between out-of-sample utility mean and volatility. These strategies are resilient to estimation errors and outperform portfolios that ignore parameter uncertainty or out-of-sample utility risk.
