Conclusion and implications
Our study highlights the research progress on the spillover effects of COVID-19 on stock markets.

Our research also suggests that policymakers and researchers design preventive strategies for stock markets to avoid the detrimental effects of future infectious diseases and pandemics. Finally, we recommend that regulators must focus on small equity investors and small firms with high debt and working capital requirements in stimulus packages during the crisis period and provide awareness against panic selling and herding
