问题如下:

In her response to Ruelas regarding risks, Maestre is most likely referring to:

选项:

A.spread risk.

B.model risk.

C.counterparty credit risk.

解释:

Solution

C is correct. Counterparty credit risk is essentially absent from exchange-traded derivatives, such as futures contracts, and can be essentially eliminated from over-the-counter derivatives, such as swaps, through inclusion of a Credit Support Annex. In contrast, model risk is implicit in the management of a defined-benefit pension plan, which is made up of Type IV liabilities (uncertain amount and uncertain timing). Further, most fixed-income derivatives contracts trade on credit risk–free government securities, and the pension plan’s assets consist of both investment-grade and speculative-grade corporate securities, making spread risk difficult to eliminate from the management of the portfolio.

A is incorrect because spread risk is very difficult to eliminate for a fixed-income portfolio containing a variety of investment grade and speculative grade corporate securities.

B is incorrect because model risk cannot be eliminated for a defined-benefit pension plan’s liabilities.

为啥不能是用错了模型呢…?model risk一般应用在什么场景啊

嗨,从没放弃的小努力你好:


model risk是指大量假设与估计带来的风险,比如假设asset portfolio中的equity、alternative 的duration为0,只有bond有duration;养老金计算负债PV时,用到的PBO或者ABO,对工资增长率等一系列参数的假设;再比如用CTD BPV/CF作为futures的BPV,这些都是model risk的表现。
