International Portfolio Diversification Is Better Than You Think

Do investors completely ignore the basics of portfolio theory? Given their over-exposure on domestic risk, investors should try to hedge this risk by picking foreign assets that have low correlation with their home assets. In the data though, we find a robust positive relationship between bilateral equity holdings and bilateral return correlations. We argue that this finding could be driven by the common impact of financial integration on cross-border equity holdings and on cross-market correlations. Indeed, when we instrument current correlations with past correlations to control for endogeneity, we recover asset demand functions that decrease with returns correlation.
