* Targetd exposure that requires tighter constraints may likely result in an increase in deviation from an optimal portfolio. However, greater or lesser degrees of skewness in a particular ESG dataset may provide multiple paths to realising the investor’s targeted exposure.
需要更严格约束的目标敞口可能会导致偏离最佳投资组合的增加。(e.g.前面的例子)
然而,特定ESG数据集或多或少的偏度可能为实现投资者的目标风险敞口(相对与最优组合optimal portfolio deviation)提供多种途径。(e.g. trade off)
请问:
虽然前面提到,对于投资组合来说限制越多,收益会低、风险会高。但是,此处ESG(结合碳排放限制,超过一定限度)会使得与最优组合的偏离度越大,想要说明什么?难道是说,考虑ESG越多,收益受到影响就会越多?那不是从侧面说明ESG不利于企业发展么?
盼复,谢谢!祝五一快乐!
