某公司项目组合管理规划（英文版）内容提要：
   The expected return of a portfolio is a weighted average of the component expected returns.The total risk of a portfolio comes from the variance of the components and from the relationships among the components. The point of diversification is to achieve a given level of expected return while bearing the least possible risk. A portfolio dominates all others
if no other equally risky portfolio has a higher expected return, or if no portfolio with the same expected return has less risk.
   The optimal combinations result in lowest level of risk for a given return The optimal trade-off is described as the efficient frontier Naive  diversification is the random selection of portfolio components without conducting any serious security analysis.
    As portfolio size increases,total portfolio risk, on average, declines. After a certain point, however, the marginal reduction in risk from the addition of another security is modest.
