问题如下图:
选项:
A.
B.
C.
解释:
老师,IR不应该是和active risk负相关吗?为什么对于unconstrained portfolio是invariant?
在constraine境下,TC下降,越激进投资,IR越低。但如果降低主动承担的风险,IR也不一定下降啊。所以其实题干中的第二个结论表述的不太严谨,我能不能这么理解?
Only conclusion two is correct. Both conclusions are correct. B is correct. 考点funmentl的应用 解析相关结论 对于unconstraineportfolio, IR is invariant to the level of active risk. 对于constraineportfolio, IR creases because lower transfer coefficient.有限制的组合的IR也与激进程度无关吧?
老师你好,请问在unconstraine况下,除了IR不会因aggressive影响,还需要注意什么呢?
对于unconstraine说,IR独立于active risk不就是与active risk(aggressiveness)无关的意思吗?statement 1为什么不对?
Only conclusion two is correct. Both conclusions are correct. B is correct. 考点funmentl的应用 解析相关结论 对于unconstraineportfolio, IR is invariant to the level of active risk. 对于constraineportfolio, IR creases because lower transfer coefficient.Level of active risk是指weight吗?
