同学,上午好。这道题比较牵强,了解下就好。
A选项错在Returns to traditional asset classes are normally distributed, whereas returns to alternative investments tend to exhibit non-normality. 传统上来说确实绝大部分的传统资产都是正态分布的,但是确实有一部分传统资产是非正态分布的,比如投机级债券、所以A的表述错误。
剩下B和C分别对应原文:
For alternative investments, even the most basic estimate of risk, the standard deviation of returns, is likely to be measured incorrectly, because of the way returns are calculated and reported.
A common approach to portfolio optimization when alternative assets are involved is a two-step process that first uses a mean-variance analysis for the traditional asset classes and then incorporates alternative assets using more sophisticated techniques, such as Monte Carlo simulation.
他们表述都是正确的。
