Abstract

Financial crises can cause financial portfolios to incur large losses. Methodologies for portfolio selection taking into account the possibility of large losses have existed for decades but their economic value is not established. This article investigates if there is economic value in reducing the probability of large losses in portfolio selection. We combine mean-variance analysis with semi-parametric estimation of potential portfolio large losses. We find that strategies that reduce the probability of large losses outperform efficient minimum variance portfolios, especially when semi-parametric estimation is used. Our results are robust to transaction costs.
