问题如下:
A trader is looking for an arbitrage opportunity relating to a bond futures based on following information:
- Quoted futures price=103
- Conversion factor=1.02
- One month remaining to expiration, no coupon during this period
- Quoted bond price=108
- AI0=0.1
- AIT=0.15
- Annual compounded risk-free rate=0.2%
The arbitrage profit is closest to:
选项:
A.0.8965
B.2.9075
C.1.3253
解释:
B is correct.
考点:fixed-income futures定价
解析:
No-arbitrage futures price:
F0(T) =(108+0.1) (1 + 0.002)1/12-0.15=107.968
市场中的futures price=quoted futures price * CF=103*1.02=105.06
arbitrage profit应该是两个futures price之差的现值
所以arbitrage profit=
求No-arbitrage futures price画图:(该题合约期间没有coupon,所以PVC=0)
老师,你好,
为什么求无套利的future price里要减AI (T), 而计算市场quoted future price 就只是乘以conversion factor,而不用减去AI(T)呢?我记得书中例题算无套利的future price的时候反而没有没有减去AI (T), 我的理解是因为期间没有coupon,所以AI (T)为0. 那这题也说了期间没有coupon。求无套利期货价格和算市场期货价格,什么时候要包括AI (T),什么时候不用?
