Insider Sales and Corporate Bond Yield Spread: Evidence from China

We study whether and how insider sales affect a firm's bond yield spreads. By examining insider sales and corporate bond yield spreads from 2011 to 2022 in the Chinese market, we find robust evidence that insider sales have a significant and important impact on corporate bond yield spreads. A one-standard-deviation increase in insider sales resulted in an increase of 11.82 bps in corporate bond yield spread. Further analysis suggests that while both the information asymmetry channel and the tunneling channel exist, bond investors do not believe that excess return from insider sales would reduce fund occupancy and alleviate default risk. We also find that ownership structure matters for the impact of insider sales on corporate bond yield spreads, where insiders in firms with more concentrated ownership structures tend to tunnel or withhold private information, whereas a more balanced ownership has the opposite effect. There is also weak evidence that the impact of insider sales on corporate bond yield spreads is larger in private firms than in state-owned ones. In addition, institutional investor ownership weakens the role of insider sales in bond pricing and, in particular, weakens the response of bond investors to insider sales in private firms.
