PurposeThis study undertakes a comprehensive investigation into the far-reaching repercussions of Covid-19 stimulus packages and containment policies on stock returns, meticulously examining a diverse array of 14 distinct markets.Design/methodology/approachThis study employed the Panel SVAR model to analyze the relationships between various policies and stock market performance during the Covid-19 outbreak. The sample comprises 5432 daily observations spanning from December 2020 to January 2022 for the 14 selected markets, with missing data excluded.FindingsThe findings reveal three consistent impacts across all 14 markets. Firstly, stock returns immediately reversed and decreased within a day when Governments tightened containment policies. Secondly, economic stimulus packages led to a fall in stock returns. Thirdly, an increasing death rate caused the stock return to decrease in the following two days. These findings are supported by the uniform impulse responses in all three shocks, including common, composite and idiosyncratic shocks. Furthermore, all inverse root tests satisfy the stability conditions, indicating the stability and reliability of Panel SVAR estimations.Practical implicationsOne vital implication is that all government decisions and measures taken against the shock of Covid-19 must consider economic impacts to avoid unnecessary financial losses and support the effective functioning of stock markets during similar shocks. Secondly, investors should view the decline in stock returns due to Covid-19 effects as temporary, resulting from anxiety about the outbreak. The study highlights the importance of monitoring the impact of policies on financial markets and the broader economy during crises. Overall, these insights can prove helpful for investment decisions and policymaking during future crises.Originality/valueThis study constitutes a noteworthy addition to the literature on behavioural finance and the efficient market hypothesis, offering a meticulous analysis of the multifaceted repercussions of Covid-19 on market interactions. In particular, it unveils the magnitude, duration and intricate patterns of market volatilities linked to significant shock events, encompassing a comprehensive dataset spanning 14 distinct markets.
目的本研究全面调查了 Covid-19 刺激计划和遏制政策对股票回报的深远影响,细致研究了 14 个不同市场的各种情况。样本包括 14 个选定市场从 2020 年 12 月到 2022 年 1 月期间的 5432 个每日观测值,并剔除了缺失数据。首先,当政府收紧遏制政策时,股票回报率立即逆转并在一天内下降。第二,经济刺激计划导致股票回报率下降。第三,死亡率上升导致股票回报率在随后两天内下降。所有三种冲击(包括普通冲击、综合冲击和特异冲击)的脉冲响应都是一致的,这证明了上述结论。实际意义一个重要的意义是,政府针对 Covid-19 冲击所做的所有决策和采取的措施都必须考虑经济影响,以避免不必要的经济损失,并支持股市在类似冲击中的有效运行。其次,投资者应将 Covid-19 影响导致的股票回报率下降视为暂时性的,是对疫情爆发的焦虑所致。本研究强调了在危机期间监测政策对金融市场和更广泛经济影响的重要性。总体而言,这些见解有助于未来危机期间的投资决策和政策制定。原创性/价值本研究是对行为金融学和有效市场假说文献的一个值得注意的补充,对 Covid-19 对市场互动的多方面影响进行了细致的分析。特别是,它揭示了与重大冲击事件相关的市场波动率的幅度、持续时间和复杂模式,涵盖了 14 个不同市场的综合数据集。

PurposeThis study undertakes a comprehensive investigation into the far-reaching repercussions of Covid-19 stimulus packages and containment policies on stock returns, meticulously examining a diverse array of 14 distinct markets.Design/methodology/approachThis study employed the Panel SVAR model to analyze the relationships between various policies and stock market performance during the Covid-19 outbreak. The sample comprises 5432 daily observations spanning from December 2020 to January 2022 for the 14 selected markets, with missing data excluded.FindingsThe findings reveal three consistent impacts across all 14 markets. Firstly, stock returns immediately reversed and decreased within a day when Governments tightened containment policies. Secondly, economic stimulus packages led to a fall in stock returns. Thirdly, an increasing death rate caused the stock return to decrease in the following two days. These findings are supported by the uniform impulse responses in all three shocks, including common, composite and idiosyncratic shocks. Furthermore, all inverse root tests satisfy the stability conditions, indicating the stability and reliability of Panel SVAR estimations.Practical implicationsOne vital implication is that all government decisions and measures taken against the shock of Covid-19 must consider economic impacts to avoid unnecessary financial losses and support the effective functioning of stock markets during similar shocks. Secondly, investors should view the decline in stock returns due to Covid-19 effects as temporary, resulting from anxiety about the outbreak. The study highlights the importance of monitoring the impact of policies on financial markets and the broader economy during crises. Overall, these insights can prove helpful for investment decisions and policymaking during future crises.Originality/valueThis study constitutes a noteworthy addition to the literature on behavioural finance and the efficient market hypothesis, offering a meticulous analysis of the multifaceted repercussions of Covid-19 on market interactions. In particular, it unveils the magnitude, duration and intricate patterns of market volatilities linked to significant shock events, encompassing a comprehensive dataset spanning 14 distinct markets.
目的本研究全面调查了 Covid-19 刺激计划和遏制政策对股票回报的深远影响,细致研究了 14 个不同市场的各种情况。样本包括 14 个选定市场从 2020 年 12 月到 2022 年 1 月期间的 5432 个每日观测值,并剔除了缺失数据。首先,当政府收紧遏制政策时,股票回报率立即逆转并在一天内下降。第二,经济刺激计划导致股票回报率下降。第三,死亡率上升导致股票回报率在随后两天内下降。所有三种冲击(包括普通冲击、综合冲击和特异冲击)的脉冲响应都是一致的,这证明了上述结论。实际意义一个重要的意义是,政府针对 Covid-19 冲击所做的所有决策和采取的措施都必须考虑经济影响,以避免不必要的经济损失,并支持股市在类似冲击中的有效运行。其次,投资者应将 Covid-19 影响导致的股票回报率下降视为暂时性的,是对疫情爆发的焦虑所致。本研究强调了在危机期间监测政策对金融市场和更广泛经济影响的重要性。总体而言,这些见解有助于未来危机期间的投资决策和政策制定。原创性/价值本研究是对行为金融学和有效市场假说文献的一个值得注意的补充,对 Covid-19 对市场互动的多方面影响进行了细致的分析。特别是,它揭示了与重大冲击事件相关的市场波动率的幅度、持续时间和复杂模式,涵盖了 14 个不同市场的综合数据集。
