Abstract

This paper develops an optimal portfolio allocation model for an investor with quantile preferences, i.e., who maximizes the t-quantile of the portfolio return. Quantile preferences allow to study heterogeneity in individuals’ portfolio choice and have a solid axiomatic foundation. We derive conditions under which the optimal portfolio allocation problem has an interior solution guaranteeing diversification and conditions under which the portfolio allocation is characterized by two regions: full diversification for quantiles below the median and no diversification for upper quantiles. These results are illustrated via simulation and empirically with a portfolio of cash, a stock index and a bond index.
