- Abstract
Market investment is always a popular method to make a profit. With different investment means, there are tens of thousands of portfolios in the market for investors to choose and combine. In order to maximize profit and minimize risk, some evaluation must be done to those portfolios. Many capital asset pricing models are used in calculating the present value and expected value of the portfolios, and one of the most popular is the model called CAPM (this refer in particular to the model from William Sharpe and John Lintner) The Sharpe ratio is also a necessary index in evaluating the value of the portfolios, which indicates the rate of the expected return against an extra unit of risk taken. The analysis on CAPM are mainly theoretical, and the core function of CAPM will be introduced. Through collecting data from The Morning Star website(cn.morningstar.com), three funds are analyzed to explain the characteristic of Sharpe ratio, which will lead to a persuative conclusion. The conclusion shows that these two models are simple and easy to understand, which means they are very popular, but they have made many assumptions that are not according with the real market environment and they made too many simplifications, which may lead to inaccurate results.
