你好,第一张图对应的题目可以得满分,基本点都回答到了。
第二张图对应的题目,优势可以得满分,但是resample MVO的缺点,按照原版书的原文,建议从以下四点中任选一条写:Criticisms include the following: (1) Some frontiers have concave “bumps” where expected return decreases as expected risk increases; (2) the “riskier” asset allocations are over- diversified; (3) the asset allocations inherit the estimation errors in the original inputs; and (4) the approach lacks a foundation in theory.
第三张图对应的题目,只解释了为什么是optimal risk budget,没有解释是不是risk parity,应该补充“the percent contribution to total standard deviation is different for all assets, the asset allocation is not risk parity.”
