The Impact of COVID-19 Pandemic on Global Stock Markets: An Event Study
Purpose: This study aims to empirically examine the immediate reaction of affected countries' stock market indices to COVID-19. Approach/Methodology/Design: The study applies an event study methodology using daily data series of stock price indices. Findings: Evidence from eleven global stock market indices shows that the first confirmed COVID-19 case announcement has had a significant negative impact on the returns. Moreover, these effects were more substantial following the WHO announcement of COVID-19 as a global pandemic on March 11, 2020. Practical Implications: The rapidly developing outbreak of the COVID-19 pandemic has depressed the affected countries' economies and caused turmoil in global financial markets. The results presented in this paper shed some light on the potential economic and social cost of COVID-19 concerns policymakers and other stock market stakeholders. Originality/value: The results suggest that stock markets have captured investors' expectations over potential adverse economic consequences of COVID-19. Moreover, there is evidence for an underreaction to the pandemic's announcement, as shown by the delayed response of stock markets in terms of significant CARs. These findings leave a wish list of topics for future research.
