ABSTRACT
This paper investigates the direct and spillover portfolio effects from the global outbreak of COVID-19. We find that an increase of the newly added cases of one specific country causes investors to significantly decrease their portfolio allocations in the outbreak countries (direct effect). Simultaneously, investors also decrease their allocations to other countries (spillover effect). In addition, we provide evidence and documentation that the transmission mechanism underlying foreign exposures matter to the above-mentioned portfolio effect. Moreover, we provide evidence for phase heterogeneity. The first wave of the COVID-19 pandemic has significant direct and spillover portfolio effects, but the impacts are weakened in second wave of the pandemic. The capital reallocation effect occurs only when the disease becomes global. Finally, our heterogeneities analysis shows that both local and spillover effects are mitigated when the economies are more developed and democratic and when the country has better health care facilities.

ABSTRACT
We study how a public health crisis affects the corporate sector at different phases of outbreak. Using an event study approach, we find significant valuation effects in a sample of Chinese listed firms following two symbolic events in the outbreak of COVID-19: (1) the lockdown of Hubei province; and (2) the containment of the disease in China and its spread to overseas. Market responded negatively (positively) to the first (second) event. Regression analysis further reveals that, following the first event, firms with Hubei (foreign) exposures earned significantly lower (higher) returns. Foreign exposures, however, had significantly negative effects on returns following the second event. The valuation effects of Hubei and foreign exposures also vary across firm ownership and industries. Our results indicate that, in a globalized world, firms' international status, internal networks and input-output linkages all play important roles in determining their exposures to the pandemic.
