Abstract: The phenomenon of information cascade widely exists in the financial market, mainly manifested in the herd behavior of investors. With the development of online social networks, stock forums provide conditions for cascading effects. Taking the stock bar forum as the research scenario, this paper used a Python Web crawler to collect forum data and empirically tested the cascading effect of the stock bar Forum. Research shows that, as proxy variables, stock popularity ranking and opinion leader posts are related to investors’ herding behavior.
