实验目的:熟练运用投资组合工具箱,学会构造有效前沿组合的方法,掌握最优投资组合的计算方法;给出投资组合VaR 的值。
实验任务:选择股票并从万得下载数据,计算证券的预期收益率、标准差和协方差,设定一组约束条件,构造最优投资组合并计算该组合的Var值。
实验设备:计算机
实验软件:Matlab2013 Wind数据库
选择一组股票作为投资标的,构造投资组合,通过估计收益率均值、计算方差、协方差,计算该投资组合权重、在险价值、画出有效前沿。(Experimental Name: Portfolio Analysis
Experimental nature: comprehensiveness and research exploration
The purpose of the experiment is to skillfully use the portfolio toolbox, learn to construct effective frontier portfolio method, grasp the best investment portfolio calculation method, and give the value of portfolio VaR.
Experimental tasks: select stock and download data from Wan De, calculate the expected return, standard deviation and covariance of securities, set up a set of constraints, construct the optimal portfolio and calculate the Var value of the portfolio.
Experimental equipment: computer
Experimental software: Matlab2013 Wind database
A group of stocks is selected as investment target, and a portfolio is constructed. By estimating the mean value, variance and covariance of the yield, we calculate the portfolio weight, value at risk and draw effective frontier.)
