摘要

在现实证券市场中，由于市场的波动及经济现象本身的不可控性以及人的主观对收益的预期和风险的承受度不同，导致预期收益率和实际收益率往往具有不可控性，难于用精确值量化.本文运用可拓学理论，对投资组合中超出风险范围的证券，通过建立证券评价选优的物元模型，设计出一套刻画股票特征的指标，设定衡量指标的权系数，计算各证券的满意度

并提出了进行投资组合变换的方法.

Abstract

With the fluctuation of the stock market

uncontrollable economy

people's different expectations of profit rates and their different degrees of endurance against risk

stock investment has uncertainty. Because of the uncertainty of expected profit rate and practical yield

it is difficult to measure accurately the profit rate. Regarding the dissatisfactory stock

it built the matter-element model of investment portfolio

designed some index of stock characters

fixed the power quotiety of scale index

calculated satisfaction degree of stock

and proposed the method to transform investment portfolio.
