这里说best risk-efficient delivery of results, 是只看风险,不结合收益来看吗?March的active risk 3.2%,也只能说明它更追踪指数啊,并不见得收益就好?

同学,你好:
这里是考察选择well-constructed portfolio的步骤:
1.In a well-constructed portfolio, we would be looking for risk exposures that are aligned with investor expectations and constraints and low idiosyncratic risk (unexplained) relative to total risk.
2.If two products have comparable factor exposures, the product with a lower absolute volatility and lower active risk will likely be preferred (assuming similar costs).
3.If two products have similar active and absolute risks, the portfolios have similar costs, and the alpha skills of the managers are similar, the product having a higher Active Share is preferable, because it leverages the alpha skills of the manager and will have higher expected returns
这里,在比较具有相似风险敞口的组合时候,假设成本相似,MARCH 具有较低的active risk, 同时active share较高,所以选择它

做题的时候被问到best risk-efficient delivery of results,主要是看什么因素?就是比较起来要active share最高的和active risk最低的对不

同学,你好, well-constructed portfolio,总结一下,就是三点:
1.选择低idiosyncratic risk的组合
2.选择lower absolute volatility and lower active risk 的组合
3.选择higher active share的组合
