Abstract: We examine the impact of economic policy uncertainty and geopolitical risk on various industries, highlighting their asymmetric effects on sectoral volatility. Furthermore, we investigate the differential effects of economic policy uncertainty and geopolitical risk on sectoral volatility, distinguishing between good and bad volatility responses. We find an asymmetric relationship between economic policy uncertainty and geopolitical risk in these industries, with economic policy uncertainty generally exerting a stronger impact on sector-specific volatility compared to geopolitical risk. During normal circumstances since the 2010s, the influence of geopolitical risk on sector-specific volatility has been relatively insignificant. However, both economic policy uncertainty and geopolitical risk have played significant roles in affecting multiple sectors during certain crisis periods, with geopolitical risk demonstrating short-term effects. These findings have important implications for both investors and policymakers. Investors can time positions using insights on policy uncertainty and geopolitical risk, while policymakers can identify vulnerable sectors.
