Abstract

We measure the economic value of diversification for international multiasset investment strategies. This study implements five existing diversification measures and proposes a novel measure of diversification, the unsystematic risk ratio (URR). Only the URR and the effective number of bets measures predict the future risk‐adjusted performance. These relations are robust to the choice of investment horizon and degree of relative risk aversion. The diversification benefits are larger for the frontier and emerging markets than for the developed markets, for multiasset strategies than for single asset class strategies, and for the pre‐crisis and post‐crisis periods than for the financial crisis period.
