passive Fixed Income management strategy

Adams states, “Generally when we evaluate similar situations, we will use a passive, as opposed to an active, management strategy for the fixed-income portfolio, which means the risk of measurement error will be greater than asset liquidity risk.”

Is Adams is most likely correct in her assessment of measurement error?

1.     Yes

2.     No, because passive management would preclude measurement error

C.     No, because asset liquidity risk is greater than the risk of measurement error

Solution

A is correct. Measurement error for Asset BPV can arise even in the classic passive immunization strategy for Type I cash flows, which have set amounts and dates. Asset liquidity can become a risk factor in strategies that add active investing to otherwise passive fixed-income portfolios and would not be applicable here.


请问为什么Type I cash flow 会有measurement error?

为什么passive 不会有liquidity risk?如果要replicate index有些bond的liquidity很低 不是会有liquidity risk吗?

嗨,从没放弃的小努力你好:


对于passive 策略来说,目标是要minimize tracking error,tracking error的来源有很多方面,其中一个很重要的方面就是估值时间点不一致导致的所用的债券价格不同,进而估值收益率出现差异,这就是measurement error。对于passive尤其是债券的passive来说,由于债券流动性较差,因此benchmark不会频繁调仓(一般都是债券到期后换仓),所以,passive管理也不会频繁调仓,measurement error的风险比债券流动性风险更重要。
