问题如下:

Based on Exhibits 2 and 3, and assuming annual compounding, the per share value of Troubadour’s short position in the TSI forward contract three months after contract initiation is closest to:

选项:

A.

$1.6549.

B.

$5.1561.

C.

$6.6549.

解释:

C is correct.

The no-arbitrage price of the forward contract, three months after contract initiation, is

F0.25 = FV0.25(S0.25 + CC0.25 – CB0.25)

F0.25 = [$245 + 0 – $1.50 / (1 + 0.00325)(0.5-0,25) ] (1 + 0.00325)(0.75-0.25) = $243.8966.

herefore, from the perspective of the long, the value of the TSI forward contract is

V0.25= PV0.25 [F0.25 – F0]

V0.25= ($243.8966 – $250.562289)/(1 + 0.00325)(0.75-0.25) = –$6.6549.

Because Troubadour is short the TSI forward contract, the value of his position is a gain of $6.6549.

中文解析:

本题考察的是t时刻求value,有重新定价法和画图法两种方法。

上述求解过程为重新定价法,即先求t=3时刻的远期合约价格F,然后和F作差后折现至t时刻即可。

如果使用画图法,与课程讲法一致:假设是long position,向上箭头表收到,向下的箭头表支出,二者相减即为所求的value。对应本题需要注意的是short头寸,因此最后求得结果需要取负号即可。

具体计算过程如下图:

因为原题的设定,假如考虑了accrued interest,那AI_t和AI_T也会抵消;如果没有这么巧合的设定,这道题是不是需要考虑两个accrued interest?

嗨,努力学习的PZer你好:


accrued interest定义如下,因此AI_t是截止到t时刻的AI,AI_T是截止到T时刻的AI

嗨,爱思考的PZer你好:


是的,如果考虑了accrued interest,则需要考虑两个accrued interest。具体来说,在计算远期合约价格F时,应将CB0.25和CC0.25中的当前时间(t=0)的accrued interest加入到对应的价格中。

在计算V0.25时,还需要加上t=0时刻到t时刻的accrued interest AI_t和t=0时刻到T时刻的accrued interest AI_T,即:

V0.25 = [F0.25 - F0] / (1 + r)^(T-t) - AI_t - AI_T

因此,在考虑accrued interest的情况下,对于本题的求解需要进行相应的调整。

Rf不变的情况下,这两个accrued interest不是相等吗?
