We investigate the relationship between product diversification and performance in the Dutch property-liability (P&L) insurance industry for the period 2007-2018. We employ a two-step approach: we first investigate the drivers of diversification and, as a second step, we investigate the impact of diversification on risk and return. Our results suggest that the impact of diversification can be beneficial, as it reduces an insurer’s risk. Diversification is however also associated with lower returns, while it is not significantly related to risk-adjusted returns. Furthermore, the impact of diversification on performance is contingent upon an insurer’s size and its extent of diversification.
