指出传统的均值 方差决策规则在度量风险方面的不足,认为风险与投资收益的偏差有关;指出了一种新的风险度量指标———风险组合偏差,同时提出了一种能够根据风险大小进行投资的决策指标———风险调整收益,并举例说明了二者在分析投资项目时的应用。
It is pointed out that the traditional mean-variance decision-making rules have some shortcomings in the measurement of risk, and that the risk is related to the deviation of investment returns. A new measure of risk-risk portfolio deviation is pointed out. At the same time, a new method is proposed to invest according to the risk Decision-making indicators --- risk-adjusted return, and an example of the two in the analysis of investment projects.
