The Stock Celecting Modle Of Quantitative Analysis And Qualitative Analysis

With the developing of Marketing Economic,security market becomes more mature and investors pay more attention to scientific investing method. This essay analyses the actual state of the research of the stock selecting modle.Because of the different the state of the nation,the developing extent of the market and the clarify of the information,when we constructe the stock selecting modle,making use of the foreign stock selecting modle directly is very limited.Acording to the analyzing and selecting of stock involve many factors including quantitative factors and qualitative factors,the essay thinks the adoption of the solution of the complicated multi-attribute ploblems is very proper and select the the analytic hierarchy process(AHP) and the fuzzy comprehensive evaluation(FCE) as the main method of the construction of the stock selecting modle. The essay analyses the factors that affect the stock prices and after consulting the standard of selecting stock of other essays,the famous investor and the famous institution, summarize the factors that affect the prices of stocks were market factor,company factor,growth ability,profit ability and so on.It chooses some important indices as samples from every factors.Using EXCEL to calculate the correlation of every two quantitative indices it deletes the less important one to the stotck prices of the quantitative indices the correlation of which is greater then 0.8.Then it uses AHP to calculate the weights of the quantitative factors and indices and the consistency of the comparison matrixes.This process prepares datas for FCE. FCE can make a whole judgement for multi-attribute problems.After using FCE to calculate the degrees of the membership of the quantitative indices it achieve the single factor judgement matrix from which we can have the the score of the the quantitative indices.Using the scores of the qualitative indices to multiply the weights of every qualitative indices,it gets the score of the qualitative indices. At last it chooses stocks according to the whole score of every stock.Using the concrete figure to test the modle proves making use of quantitative analysis and qualitative analysis to construct the stock selecting modle is appropriate and the forcast of the modle is very exact.
