中國(guó)股票市場(chǎng)噪聲交易風(fēng)險(xiǎn)實(shí)證研究
[Abstract]:With the globalization of the economy, the financial markets of all countries have also entered the era of globalization. The interaction between the real economy and the financial market is becoming more and more obvious. The volatility of the financial market has a great impact on the real economy. Whether it is the historical Holland tulip crisis, the British South Sea crisis and the 1929 US stock market crash, or 2008 The global financial crisis caused by the American subprime crisis has greatly affected the global real economy. The subprime crisis in the United States has not fully recovered the global economy. Countries are still facing high unemployment, low economic growth, monetary tightening, and some countries facing a serious debt crisis. Financial market bubbles. The foam seriously interferes the normal operation of the real economy and affects the steady development of the financial market. Therefore, it is of great significance to maintain the stability of the financial market, reduce the bubble of the financial market, and supervise the behavior of investors for the smooth and rapid development of our country's economy.
The financial bubble and many other anomalies in the market have made the traditional financial theory dominated by the "effective market hypothesis" more and more questioned and challenged. The traditional financial theory can not explain these anomalies. In the complex social environment, the transmission of information will be affected, and it is difficult for investors to keep it at the same time. The decision of the rational person is influenced by many factors. The behavioral finance theory, which combines sociology and psychology with financial theory, has been pursued by many scholars and has developed rapidly. Noise trading is one of the hotspots of behavioral finance theory and also the focus of many scholars. Whether there is a noise transaction, whether the noise transaction can survive for a long time and the size of the noise trading on the market, the study of these questions will be of great theoretical and practical significance to reducing the degree of noise trading in the stock market, reducing the risk of noise trading, maintaining the stability of the stock market and maintaining the efficiency of the market.
This paper firstly explains the market anomalies through the behavioral finance theory, leads to the noise transaction, and fully explains the cause of the noise transaction. Secondly, it proves that the noise transaction can exist in the stock market for a long time through the DSSW model, and then through the comprehensive analysis of the situation of the noise trading and the value of the noise transaction risk in the stock market of our country. Finally, the conclusion is drawn. The contents of each chapter are as follows:
The first chapter, introduction, elaborates the research background and the significance of the topic, and points out the structure, main work and shortcomings of this article.
The second chapter, literature review. Through the review and combing of relevant literature at home and abroad, the relevant literature is divided into three categories according to the purpose of writing, and the research results and research status of noise trading are expounded comprehensively, which lays the foundation for the writing of this article.
In the third chapter, the causes of noise trading and the survival mechanism are analyzed. From the shortcomings of the traditional financial theory, this chapter leads to the behavioral finance theory, and then analyses the cause of the noise transaction in a detailed way from the perspective of behavioral finance theory, and then proves that the noise trader can be self - trading with the rational trader through the DSSW model. We have created the living space and thus exist in the market for a long time. This lays a theoretical foundation for this study.
The fourth chapter is a descriptive analysis of the noise trading in China's stock market. This chapter compares the price earnings ratio, turnover rate and noise factor of the Shanghai and Shenzhen two cities with the corresponding indexes of the western mature financial market, and analyzes the overall situation of the noise trading on the stock market in China.
The fifth chapter is an empirical study on the existence of noise trading in China's stock market. Based on the random walk model, this chapter tests whether the daily return sequence of the Shanghai and Shenzhen two cities conforms to the distribution, and studies the existence of the noise trading in the Chinese stock market.
The sixth chapter, the empirical analysis of the size of the noise trading risk in China's stock market. This chapter calculates the value of the noise transaction risk of each stock through the BAPM model and the CAPM model, and examines the situation of the noise transaction risk from the micro point of view. At the same time, it shows that the BAPM model is more reasonable than the CAPM model in calculating the asset risk premium coefficient.
The seventh chapter, conclusions and policy recommendations. Based on theoretical analysis and empirical results, the conclusions of this paper are obtained and corresponding policy recommendations are put forward.
The conclusion of this paper is that noise trading can survive in the stock market for a long time. Compared with the stock market in mature western countries, there is a relatively serious noise transaction in China's stock market; noise trading during the bull market is more obvious than that during the bear market; there are many different sizes in China's stock market, which can not be ignored. Noise trading risk.
