Social media, investor-company interaction and insider trading profitability: Evidence from China

Abstract

The emergence of social media enables minority shareholders to participate in corporate governance by making their voice heard. This study examines the effect of social media interaction between minority shareholders and companies on insider trading profitability. Using the “Easy interaction” platform in China, we find robust evidence that social media interaction significantly reduces the profitability of insider trades. This negative effect is stronger for firms with higher management shareholdings, poorer information environment, and less government involvement. Overall, our findings indicate that social media can play a role in corporate governance by restricting the profits of opportunistic insider trading activities.
