Stock Overvaluation, Management Myopia, and Long-Term Firm Performance

Abstract

How does stock overvaluation in secondary financial markets affect long-term firm performance when significant corporate “insiders” seek to realize self-benefit? Using a sample of Chinese listed companies from 2007 to 2018, we find that overvaluation of stock price has a negative impact on long-term firm performance. Moreover, our results show that management myopia mediates the relationship between stock overevaluation and long-term performance. Our study enriches the discussion of stock overvaluation and extends the management myopia literature by considering unique aspects of the irrational behavior of firm decision makers, providing implications for governments to improve their capital market reform and development.
