A Series Of Risk Portfolio Models Considering Multiple Indicators And Its Application

Traditional portfolio theory mainly focuses on the price of financial products to achieve the best advantages of portfolio selection.However,more and more investors and institutions are now paying more attention to multiple types of indicators of investment objects and investors' risk attitudes.The investor's risk attitude and multiple types of indicators play an important role in modern portfolio theory.In terms of application,first of all,the selection of multiple types of investment portfolios and the measurement of investor risk attitudes can help investors better choose investment portfolios according to their preferences,and secondly,it can help the People's Bank of China and the China Banking Regulatory Commission.Supervision by some regulatory agencies such as China Securities Regulatory Commission and the stabilization of the financial product market will also help financial institutions such as banks and securities to launch investment and wealth management products that meet investors' risk preferences.Therefore,solving these two problems under certain conditions is of great significance to the macroeconomic control of economic stability and the micro-individual economy's asset appreciation and preservation and reduction of risk.Therefore,it is important to consider portfolio research that combines multiple types of indicators and risk attitudes.And how to accurately measure the risk attitude of investors is a crucial practical issue in modern portfolio theory.In order to solve this problem,this paper uses case study method,risk scenario simulation method,quantitative research method,cost and benefit analysis method to control the risk attitude coefficient of the fund allocation research model under the minimum risk.The case study method mainly uses investigative methods to analyze the investor's risk attitude.The risk scenario simulation method mainly uses the investor's historical selection data to sort its risk preferences.The quantitative research analysis method is based on investor selection.To measure risk appetite,and the quantitative cost-benefit analysis method is based on the minimum risk of fund allocation research with risk minimization as the objective function.The introduction of the GARCH model is used to refine the fund allocation and assumptions that include risk attitude Based on the constraints of the model,an optimal flow allocation model in the form of planning with optimal capital allocation and minimum risk constraints was finally formed.Finally,based on the risk-profit analysis of Shenzhen-listed stocks,the investor's immediate risk attitude was analyzed,and the validity and practicability of our model was studied by considering multiple indicators of investment objects.The structure of this paper is as follows: Section 2 introduces the current literature review of portfolio research.Part 3 introduces the relevant theories of portfolio theory,risk measurement and property analysis,the theoretical basis and algorithm formula of the calculation model of multi-indicator and risk attitude,expounds the related concepts and methods of multi-indicator portfolio,and analyzes the investment portfolio.Different types of risk attitudes in the process.On this basis,the necessity of introducing multiple indicators and risk attitudes is analyzed.Part 4 constructs a two-level portfolio theoretical model and introduces multi-category risk attitude estimation.Part 5 introduces the two-level portfolio model under multi-category risk attitude measurement,and analyzes the relevant properties of the new model.Specifically,it also establishes four portfolio measures under the risk measure.It also analyzes case studies and risk scenario simulation methods.Quantitative research method and volume-cost-benefit analysis method combined with portfolio model analysis.Section 6 introduces four different portfolio models for empirical analysis,and applies,compares,and analyzes them.And give a comparative analysis of advantages and disadvantages.The article draws the corresponding conclusions in Section 7,meanwhile,it analyzes the advantages and disadvantages of the specific analysis methods,as well as the future directions for attention and research.The reason why the article uses data from the Shenzhen Stock Exchange for one year to conduct empirical research is mainly because modern portfolio research methods focus on analyzing too much historical data,and the model constructed in this article is to solve the current investment object 's historical data.There are no investment objects that can be analyzed according to traditional portfolio theory.The case results show that it can reduce part of the investor's risk,which shows that the combination of the calculation of risk attitude and the selection of multiple indicators in modern portfolio theory is very necessary.
