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.  

Key words: investment portfolio; matter-element model; extension evaluation; extension transformation
