[Abstract]:In recent years, the banking industry has not only developed and expanded, but also obviously played a more and more important role in the economic development of our country. The banking industry has been developing rapidly in recent years, and the government has introduced macro policies to restrain capital overheating in succession, and many small and medium investors are also in favor of the banking enterprises. For investors, an important source of information for investors is the annual report of the enterprise. Based on the information disclosure theory, this article tries to explore the factors that affect the duration of the price rise or fall after the disclosure of the annual report information. The system diagram of various factors can not only provide reference for the related behavior and decision of the investors, but also provide reference and inspiration for other enterprises and individuals to examine the performance of the banking and capital markets.
On the basis of the review of the results of accounting information disclosure and stock price response at home and abroad, this paper sets up a model of stock price response after the annual report of the listed bank, which is based on the banking industry. Combined with the characteristics of the annual report of China's listed banks, the research object of this paper is 16 banks in 2008, 2009 and 2010 for three years. The duration of the rise or decline of the stock price after the annual report is disclosed. Estimates of the Kaplan-Meier in its use of survival analysis results in a continuous rise in the stock price and the distribution of the fall time. The results show that there are significant differences in the distribution of the two cases of the stock price rising and falling time. Some key financial indicators and stock trading technical factors will affect the duration of stock price volatility. In this paper, the Cox risk proportion model is introduced to fit and analyze the sample data. The results show that the 8 main financial indexes of the bank listed companies, the change of the stock volume and the transaction price are the influence of the volatility of the stock price. 10 of the most critical variables of time. By comparing these factors, this paper draws a conclusion that accounting information has a greater impact on the duration of stock price changes than technical factors. Finally, this paper, on the basis of investigating the characteristics of the report of the listed companies of the banking industry and combining with the status of the securities market in China, discussed the origin of the conclusions more deeply. As well as the enlightenment that can be obtained from the conclusion, it also puts forward the direction for future research.
