Dataset for the analysis of stock price responses to African Swine Fever Outbreaks in China

The African Swine Fever (ASF) outbreaks in China since 2018 caused a more than 100 million decline in its hog inventory. Leveraging publicly available announcements of ASF outbreaks and daily stock prices data from 25 major publicly listed hog companies from China and eight major hog exporting countries, we use the event study method to estimate firm-level abnormal stock price responses to China's ASF outbreak announcements for both Chinese and foreign hog companies. This article describes the data used in the research article “A Fortune from misfortune: Evidence from hog firms’ stock price responses to China's African Swine Fever outbreaks” (Xiong et al., 2021). The daily stock price data in this article can be applied to other events that also occurred during the same sample period using a similar event study approach.
