踏空對機(jī)構(gòu)投資者投資行為的影響研究
[Abstract]:Originally, institutional investors are the dominant forces in the stock market, but institutional investors have become a common phenomenon. There are not only a lot of institutional investors, but also many institutional investors. With the gradual improvement of the structure of China's financial market and securities market, institutional investors undertake the historical mission of guiding rational investment, adjusting the financial structure, promoting the reform and innovation of the economic system, and promoting the sustainable development of the economy. The investment behavior, investment idea, investment style and management level of institutional investors play an important role in the trend of securities market, and even the structure and institutionalization of the whole market. The purpose of this paper is to analyze and test whether institutional investors will take positive feedback, reverse trading and herd behavior when they go short. These irrational investment behaviors increase the volatility of the market and lead to stock market bubbles. There is a serious risk of a financial crisis. Therefore, based on the inherent requirements of the stock market and institutional investors' interactive development, it is of great theoretical value and practical significance to study the impact of the emptiness on the investment behavior of institutional investors. This paper first discusses the factors that affect institutional investors' short-selling, and reveals the reasons of institutional investors' short-selling from the aspects of policy changes, noise trading, information disclosure of listed companies and cognitive psychological deviation of institutional investors. Then, the formation mechanism of institutional investors' positive feedback trading behavior, reversal behavior and herding behavior is analyzed theoretically, and the influence of blanking on institutional investors' investment behavior is explained. On this basis, select the bull market, bear market sample stock, using the data model and dynamic interval comparison method, to carry on the empirical analysis to the institutional investor investment behavior based on the short-term. According to the theoretical and empirical analysis of the influence on institutional investors' investment behavior, this paper obtains that the institutional investors have obvious positive feedback trading behavior and herding behavior, the positive feedback trading behavior in bull market, herding behavior is stronger than bear market, and the positive feedback trading behavior in bull market is stronger than that in bear market. The reverse behavior exists only in the bull market. Finally, according to the conclusion of the article, in order to reduce the occurrence of institutional investors' short flight and the impact of the stock market, the author puts forward some targeted policies and suggestions from the perspective of regulators, listed companies and institutional investors themselves. Such as weakening the effect of policy market, vigorously developing diversified institutional investors, the obligation of listed companies to do well in information disclosure, and establishing a more reasonable performance evaluation and entrustment incentive system for institutional investors, and so on. In order to promote institutional investors and China's stock market more healthy development.
