This study examines the role of accounting information posted in Naver stock message boards. With the growth of Internet use and the ease of access to stock information, many people are posting and reading messages in Internet stock message boards. However, internet message postings are anonymous and the content of the messages can vary from value-relevant information to random chatters. Based on the premise that accounting data is value-relevant, among all the messages, we expect that messages with accounting information would induce retail investors’ stock trading and lead to more stock trading and greater stock volatility. Using Python-based web crawler to collect all messages posted in Naver stock message boards, we sort messages into those that contain accounting words and those that do not. Our empirical analyses show that messages containing accounting information are positively related to both stock trading volume and stock price volatility. These results can be interpreted as stock message boards serving as a channel of word-of-mouth and retail investors being influenced by messages with accounting information. This study extends the literature on the stock market influence of message boards and helps understand the information processing of retail investors.
