The Empirical Study on Risk Measures and Portfolio Optimization Models for Securities Investment

Abstract

对证券投资风险的关注和研究,由来已久。1952年Markowitz提出了以证券投资收益率方差计量风险的思想,创立了著名的Markowitz投资组合模型,开创了定量化计量风险的先河。但是,随着研究的深入,后人发现Markowitz模型存在着不可回避的重大缺陷,尤其是用方差来度量风险的方法从它开始诞生起就受到了人们的广泛批评。针对Markowitz模型的缺陷,后来学者又提出了半方差、下偏矩、VaR、ES等风险度量模型,并在这些度量模型的基础上建立了新的投资组合优化模型。本文先从理论上对比分析了方差、半方差、下偏矩、VaR、ES等风险度量模型的优缺点;然后在一致性风险测度的公理体系下详细证明了这些模...There have been a long time in the research on the risk measure for securities investment. Markowitz brought forward the thought of measuring risk by the variance of return of the securities investment and established the famous portfolio model. Markowitz’s portfolio theory opened the new times of quantitive analysis of risk.But with the deeper research,people have found many defects of Markowitz’...学位:经济学硕士院系专业:经济学院财政金融系_金融学(含保险学)学号:20024202
