Sharpe Ratio=(Mean of portfolio return - Risk-free return) / standard deviation of portfolio return这个公式Mean of portfolio return就是投资组合的收益率的平均值,risk-free return就是当地没有风险的回报率,也就是放在银行当中的回报率,比如美国的银行利率就接近于0,standard deviation of portfolio return就...

Objective function of this model is a nonlinear interval valued function. A solution methodology is developed for this model to obtain an efficient portfolio which provides the upper and lower bound of maximum value of the Sharpe ratio. The theoretical development is illustrated in a portfolio ...
A new class of set-quality indicators, the Sharpe-Ratio Indicator, combining the selection of solutions with fitness assignment has been recently proposed. This class is based on a formulation of fitness assignment as a Portfolio Selection Problem which sees solutions as assets whose returns are ...
