This article studies the relationship between the COVID-19 epidemic, public sentiment, and the volatility of infectious disease equities from the perspective of the United States. We use weekly data from January 3, 2020 to March 7, 2021. This provides a sufficient dataset for empirical analysis. Granger causality test results prove the two-way relationship between the fluctuation of infectious disease equities and confirmed cases. In addition, confirmed cases will cause the public to search for COVID-19 tests, and COVID-19 tests will also cause fluctuations in infectious disease equities, but there is no reverse correlation. The results of this research are useful to investors and policy makers. Investors can use the number of confirmed cases to predict the volatility of infectious disease equities. Similarly, policy makers can use the intervention of retrieved information to stabilize public sentiment and equity market fluctuations, and integrate a variety of information to make more scientific judgments on the trends of the epidemic.
本文从美国的角度研究了 COVID-19 疫情、公众情绪与传染病股票波动之间的关系。我们使用了 2020 年 1 月 3 日至 2021 年 3 月 7 日的周度数据。这为实证分析提供了充足的数据集。格兰杰因果检验结果证明了传染病股票波动与确诊病例之间的双向关系。此外，确诊病例将导致公众搜索 COVID-19 检测，COVID-19 检测也将导致传染病股票波动，但没有反向相关关系。这项研究的结果对投资者和政策制定者都很有用。投资者可以使用确诊病例的数量来预测传染病股票的波动。同样地，政策制定者可以利用检索信息的干预来稳定公众情绪和股票市场波动，并整合各种信息，对疫情趋势做出更科学的判断。
