[Abstract]:This paper makes an empirical study on the impact of significant shareholder reduction on the share price of gem, and draws a conclusion through data analysis: the reduction of significant shareholders will have a negative impact on the share price, among which market factors. Whether the senior executives themselves reduce their holdings, the way they reduce their holdings, the price-earnings ratio, the amount of market value and the proportion of the total share capital have a significant impact on the stock price; And the market factor is the most important factor that affects the stock price in the short term. But the proportion of actual controller and core technical team is small among the important shareholders, and the scale of gem is not large. Finally, the paper puts forward some suggestions to the policy makers to optimize the management system of listed companies on the gem. Strengthen information disclosure and protect the interests of the majority of small and medium-sized investors. Encourage major shareholders, especially actual controllers and core technicians, to extend the lock-up period and increase the value of stock investment; And improve the gem restrictions on the sale of shares reduction provisions.
