In the CAPM theory,we know that any rational investor will take the market portfolio as his optimum risk protfolio when he optimizes his investments. Many researches also tell us that the passive strategy is effective. People who simply invest the market index will do as good as those taking in trouble with the information or technological analysis.

In the CAPM theory,we know that any rational investor will take the market portfolio as his optimum risk protfolio when he optimizes his investments. Many researches also tell us that the passive strategy is effective. People who simply invest the market index will do as good as those taking in trouble with the information or technological analysis. However,the great number of the securities in the real market makes it impossible to invest on the synthetic index with any limited capital. So a pragmatic method using both cluster analysis and MTV model is introduced in this paper to select an index protfolio. This method allows us using only a few of stocks to make a portfolio which performance is in accordance with the selected index. Moreover,with the help of SAS and Excel,the authors make such a protfolio with 10 stocks chosen from 50 arbitrarily selected stocks in the Shanghai Stock Exchange Market,such a portfolio is also good in forecasting.

根据Markowitz组合证券投资理论 ,在一定的假设下 ,投资者优化其投资组合的结果必定是以市场证券组合为其最优风险资产的投资组合。国外许多研究也表明消极投资策略是有效的 ,投资者只要按照某个较有代表性的股票市场综合指数中的每个股票所占权重投资每个股票 ,就可以消除股票的特有风险 ,达到很好的投资效果。但是 ,股票市场上股票种类繁多 ,有限的资金很难按照股票市场综合指数去投资。本文提出了一种利用聚类分析和MTV模型 ,可以以有限的几种证券的资产组合去逼近市场综合指数的方法。然后以上海股票市场为例 ,从任意选取的 5 0种股票中使用本方法抽取不超出 10种股票 ,用它们的组合去逼近上证综合指数 ,取得了比较满意的逼近和预测效果。
