This paper examines if industries with higher economic policy uncertainty (EPU) sensitivity also respond differently to the evolution of COVID-19 pandemic. Initially, industries are allocated into decile portfolios according to their sensitivity to the US-EPU shocks, then portfolio returns are conditioned against changes in daily cases and deaths, respectively. After controlling for the standard risk-factors of equity returns, neither the cases nor deaths can load significantly against the returns of portfolio with the highest negative EPU exposure. However, industries which respond positively to the US-EPU shocks also respond positively to increases in cases and deaths.
