同学你好,可以参考讲义或冲刺笔记上的总结,4个缺陷如下
(1) Some frontiers have concave “bumps” where expected return decreases as expected risk increases; 有时候会出现预期风险提高导致预期收益下降
(2) the “riskier” asset allocations are over-diversified; 高风险资产被过度分散化了
(3) the asset allocations inherit the estimation errors in the original inputs;输入变量的误差会导致资产配置结果出问题
(4) the approach lacks a foundation in theory;缺乏理论基础
