Abstract

Using both mean-variance portfolio optimization (MVPO) and stochastic dominance (SD) approaches, this paper investigates whether international diversification and home bias inertia are substitutes or complements. More specifically, we compare daily closing prices of 30 US stocks and the stock indices from American, Latin American, and Asian financial markets, including both emerging and major markets. Results from the MVPO show that a domestic diversification strategy performs better for any risk level up to 0.5%, whereas international diversification performs better for any risk level higher than 0.5%. Some results from the SD test support international diversification, some promote home bias, and still others conclude that there is no difference between investing domestically and internationally. However, our findings show that one could not find any single internationally diversified portfolio that dominates all domestically diversified portfolios and, similarly, one could not find any single domestically diversified portfolio that dominates all internationally diversified portfolios. Our SD findings also recommends that investors have a “home bias” if they prefer less risk and to be “internationally diversified” if they prefer higher risk.
