Capital market and public health emergencies in Chinese sports industry based on a market model

Abstract

The public health emergencies have had a significant impact on the world economy, and the sports industry has been no exception. This study employed StataMP-64 software and event study methodologies to examine the reaction of the Chinese sports industry's capital markets to the outbreak of public health emergencies. The event study method, which is becoming increasingly popular in the field of economics and management, is well-suited for evaluating the impact of specific events on stock returns in the capital market. This method has also garnered significant interest in the sports industry. In this study, the expected return is calculated using the classical market model, and the cumulative abnormal return and average cumulative abnormal return were calculated for each sports company during the period of the Wuhan "city closure" event and the inflection point event. The Wilcoxon non-parametric test has been used to examine the significance of the abnormal return. The results indicate that the event study method, applied to a procedural market model, is effective in analyzing the capital market's response to the public health emergencies outbreak in the Chinese sports industry.
