Against the Gravity as a Jenga Tower? Asset Growth and Stock Price Crash Risk

Abstract

Does growth lead to stock price crashes? In this study, we find that total asset growth positively relates to future crash risk. Consistent with the managerial empire-building incentive, agency problems tend to accentuate the asset growth-crash risk relationship while accounting conservatism attenuates the relationship, suggesting that not all growth is harmful. We also find corroborating evidence from overinvestment estimation and a quasi-natural experiment that reduces managers’ empire building incentive. Despite the popularity of studying asset growth and future stock returns in the literature, our focus on higher moments of returns sheds light on the consequences of asset growth for stock prices.
