Firm-level return dispersion and correlation asymmetry: challenges for portfolio diversification
AbstractThe main purpose of this article is to study whether firm-level return dispersions might have any significance in explaining asymmetric return correlations observed in equity market returns. Correlation asymmetry, in particular increased return correlations conditional on downside moves, implies that portfolio diversification will not be as successful during bear markets - periods during which portfolio diversification will be most needed. Similarly, low firm-level return dispersion imply that stocks within the portfolio behave the same way, making diversification harder. It is found that asymmetric correlations are associated with asymmetric firm-level return dispersions. The results indicate that portfolio managers need to not only take into account the asymmetry in return correlations but also be aware of how firm-level return dispersions behave during such periods when they need diversification most.
