Abstract: We examined the information dissemination role of social media in capital markets by using Chinese intraday trading data from 2010 to 2016. To isolate the information dissemination impact of social media in capital markets from the information content of public earnings announcements, we take advantage of the news released by Microblog (the Chinese Twitter) after earnings is officially announced. We focus on one-trading-hour market reaction after Microblog announcement, and find that news released by Microblog can trigger market reactions; the more detailed Microblog news and the more audience of a Microblog account, the stronger the market reaction. We also find that the market reaction is mainly driven by small investors. Compared to large investors, small investors make stronger market reactions; small investors also react more to /Microblog news with more detailed format and larger size of audience. Small investors can get more profits (or lose less) for firms with Microblog earnings news accompanied than without. In all, the findings in this study can help us better understand the dissemination role of social media in capital markets, especially its positive effect on small investors.
