Financing Constraints and Stock Price Volatility Empirical Evidence from Shanghai and Shenzhen A-share listed Companies

Abstract

Based on the theoretical analysis of financing constraints and stock price volatility, the hypothesis of “corporate financing constraints inhibiting corporate stock price volatility” is proposed. After data cleaning, the cross-sectional data based on A-share was used to make an empirical analysis of the relationship between financing constraints and stock price volatility of listed companies in 2018 through regression model. The study found that when companies relax financing constraints, due to widespread overinvestment, the stock price of companies will fluctuate more. In addition, we have shown that by replacing the return of financing constraint indicators and the regression of subsamples based on enterprise size, market type and ownership, the conclusion of the study is more robust. The research reveals the mechanism of the impact of financing constraints on the volatility of corporate stock prices. The conclusions have practical significance for investors, corporations and relevant regulatory authorities.
