问题如下：
For those who are interested in allocation to less liquid asset classes, a portfolio manager should tell them that:
选项：
A.Common illiquid asset classes have several accurate indexes
B.The overall illiquid asset classes perform better than liquid asset classes
C.The risk and return characteristics of illiquid asset classes are often dominated by idiosyncratic risk.
解释：
C is correct.
考点：allocating to less liquid asset classes
解析：流动性差的资产类型面临几个问题，一是缺少精准的指数（A错），即使有track的成本也非常高，所以整体的业绩如何很难判断（B错），二是很难通过分散化消除非系统性风险（C正确）。
A的意思不就是只有很少的精确指数么？那不就是缺少精确指数吗
