这道题如果题干的IC、TC调换一下是对的吗?

NO.PZ2018091701000042

问题如下:

An analyst makes two conclusions about full fundamental law of active management:

Conclusion one: The information coefficient describes how the realized returns correlate with the active weights.

Conclusion two: The transfer coefficient describes how the realized returns correlate with the forecasted active return.

Which of the following statement is correct?

选项:

A.

Conclusion one is correct.

B.

Conclusion two correct.

C.

Neither conclusion is correct.

解释:

C is correct.

考点考察full fundamental law 里面每一个变量的含义

解析IC是衡量基金经理讲话的靠谱程度也就是他预测的和他真正能实现的之间的关系

TC是衡量基金经理能实现的程度也就是他是否收到仓位的限制比如是否能做空是否可以举杠杆是否可以用衍生品管理风险等等

同学你好,

不能直接调换。

Conclusion one的“the realized returns correlate with the active weights”并不是TC。没有这种组合方式。

但Conclusion two的“the realized returns correlate with the forecasted active return”是IC。

附IC和TC的定义,可以对比一下。

IC:Correlation between the forecasted active returns, μi, and the realized active returns, RAi

TC:The correlation between any set of active weights, Δwi, and forecasted active returns, μi
