[Abstract]:Since the China Securities Regulatory Commission promulgated and implemented the "measures for the Administration of Securities issuance of listed companies" in 2006, because of the relatively short approval process, the long-term stability of the financing obtained, the low threshold and the advantages of a certain discount for investors, etc. Listed companies and investors favour them. 2014 to 2016 was the fastest growing year for growth, with only 281 actual offerings in 2013, with 3440,400 in total. 1.8 billion yuan, in 2016, the actual number of annual fund-raising 794, the actual size of the collection reached 1, 008. 9.9 billion yuan, an increase of 423.3 percent over 2013. Five, set a record high. However, sometimes due to the market environment, the company's fundamental changes and other reasons, after the implementation of the fixed increase, the secondary market share price fell below the fixed issue price of the "directional issuance break phenomenon." With the constant increase in the number of times and the constant increase in the size of the phenomenon has become frequent. Most scholars at home and abroad mainly focus on the announcement effect of fixed increase announcement, the theory of large shareholder support and encroachment, and the short-term effect of fixed growth of listed companies, etc. The breakthrough point of this paper is the breaking phenomenon before the release of the ban, which is relatively novel. In this paper, the stock price trends of the target companies in China's A share market from 2014 to 2016 after the implementation of directional additional offerings to the day of lifting the ban are statistically analyzed and screened. The sample data are divided into the bull period from 1 January 2014 to 31 May 2015, the bear market stage from 1 June 2015 to 28 February 2016 and the full sample period from 1 January 2014 to 28 February 2016. The proportion of major shareholders subscription, the proportion of fixed increase scale to total market value size, circulating market value, gross profit rate, net asset return rate, enterprise nature, Shanghai Composite Index rise and fall in the same period eight independent variables, using SPSS software to carry out multivariate linear regression, Analysis of the largest increase after breaking to the lifting of the ban on the relevant factors. The results show that the maximum break ratio, gross profit margin, enterprise nature, the rise and fall of Shanghai Composite Index in the same period and the five variables of constant are significant. In the bear market stage, the maximum break ratio, the proportion of constant increase and market value, the circulating market value, the rise and fall of Shanghai Composite Index and the constant five variables are significant. In the whole sample interval, the maximum break ratio, circulation market value, gross profit margin, enterprise nature, the rise and fall of Shanghai Composite Index in the same period and six variables of constant are significant. The multivariate linear regression equation based on the whole sample data is the best one, and there are many significant variables. The reason may be that the total sample data is large and the influence of market environment and other factors on the regression results can be well eliminated when multivariate regression is carried out. Finally, according to the conclusion, this paper puts forward the investment strategy suggestions based on the phenomenon of directional placement break, which has strong practical significance.
