可以详细解释这3个statement,到底错在哪里啊？解释看不懂

1. Illiquid assets offer both diversification benefits and an expected return discount relative to similar liquid assets as compensation for illiquidity.
2. Easily tracked indexes in asset classes similar to that of an illiquid asset often do not represent the non-idiosyncratic risk of the illiquid asset very accurately.
3. Unfortunately, there are no low-cost passive investment vehicles available to allow one to closely track the aggregate performance of less liquid asset classes.

Which of Gruber’s statements regarding illiquid assets is most accurate?

1. Statement 1
2. Statement 3
3. Statement 2

B is correct. Statement 3 is the most accurate. Low-cost passive vehicles for tracking performance exist for publicly traded liquid assets but do not exist for illiquid assets.

A is incorrect. Statement 1 is incorrect because an illiquid asset usually has a premium associated with its return due to the illiquidity.

C is incorrect. Statement 2 is incorrect because easily tracked indexes for an asset class usually do not capture the idiosyncratic risk component of less liquid assets.
