Abstract

This study examines whether video-based social media influences stock price crash risk. Using YouTube data regarding Korean listed companies’ stocks from 2014 to 2022, we find that the number of YouTube videos related with the stock is negatively associated with stock price crash risk, with this effect being more pronounced in the post-COVID-19 period. The results reveal that YouTube videos conduct informational and disciplinary role, and thus reduce excessive negative market reactions. Additionally, the negative relation between the number of YouTube videos and stock price crash risk is more pronounced for firms with high information asymmetry. Overall, this study provides evidence that YouTube functions as an important platform for providing and sharing information regarding the stock market.
