Abstract

The World Health Organization (WHO) declared the coronavirus disease, which broke out in early 2020, a “public health emergency,” triggering significant problems to the Chinese economy. The pandemic has had a massive effect on the majority of industries. This article will apply the Event Analysis Approach based on Granger Causality Test to examine the epidemic’s influence on the stock returns of public companies in China’s pharmaceutical industry by using the Shenwan Pharmaceutical Biological Index as an example. The Granger causality test is a statistical hypothesis test used to determine if one time series can be used to predict another. If the probability value is less than any α level, then the hypothesis would be rejected at that level. The research findings reveal that the COVID-19 pandemic has a substantial positive impact on the profitability of China’s pharmaceutical sector, although the influence is only temporary. The importance of studying the impact of epidemics on capital markets is that the findings can provide a theoretical basis and practical recommendations for regulators and investors to make decisions during emergencies.
