Analysis Of Investment Value Of Rare Earth Listed Companies

With the development and upgrading of rare earth products and the rapid development of rare earth market in China,more and more investors pay attention to the investment value of rare earth listed companies.It is very important to make a thorough study on all aspects of target listed companies before carrying out investment activities,and the effect is remarkable.At present,the analysis of investment value of rare earth listed companies has become a hot issue in the investment market.This paper makes a detailed and comprehensive analysis of the investment value of rare earth listed companies in different ways from the technical analysis and the company’s investment value analysis.In this paper,the theory and method of investment value analysis are carefully sorted out and summarized before in-depth study,and the present situation of rare earth industry development at home and abroad is analyzed in detail.Because the rare earth permanent magnet plate index is affected by many factors and the data is not stable,the regression model is established by regression analysis method to determine the correlation and explanatory coefficient between the rare earth permanent magnet plate index and the rare earth index,the rare earth price index and the price of rare earth products.After that,the REPM plate index is taken as indirect variable,and the REPM plate index,REPM price index and REPM product price with relatively stable data are selected as direct variables to determine the expression equation.In order to predict the future trend of rare earth permanent magnet plate index,ARIMA model is established to predict the rare earth index,rare earth price index and monthly index of rare earth product price in 2019.Finally,the model formula is obtained through regression analysis to calculate indirectly the rare earth permanent magnet plate index.This method aims to establish a "dynamic" model and increase the accuracy of prediction.The accuracy of the prediction model is high.The monthly average error rates are 4.35%,4.04% and 1.8% respectively.The prediction results are accurate.It can provide investors with the trend of rare earth permanent magnet plate index in 2019,judge investment opportunities and avoid blind investment.Selecting 12 large and medium-sized rare earth listed companies in China from the way of investment value analysis,using data from 2015 to 2016,this paper first uses factor analysis and K-means clustering method to evaluate the investment value of rare earth listed companies from six aspects: price,resource reserves,receipts,sales,R&D and industrial policy changes.In order to evaluate the investment value of listed companies carefully and comprehensively,the evaluation model divides 12 rare earth listed companies into three categories,and divides them into four sections according to the classification threshold value: excellent,good,medium and poor.Thus,12 companies can be distinguished by category and by "good medium to poor" interval,which can provide investors with the most intuitive corporate performance and evaluation results.Secondly,based on the financial data of 12 rare earth listed companies,five first-level indicators and seventeen second-level indicators are selected to establish an investment value analysis system for rare earth listed companies.At the same time,according to the comprehensive score of the indicators,we rank the enterprises,and get the analysis results of investment value and the companies with higher investment value.The results can provide decision-making reference for investors.
