为什么这道题straight bond 不能用从后往前的方法折呢?((101.55/1.012515+1.55)/1.012012+1.55)/1.01=99.7079
NO.PZ201712110200000304 问题如下 Baseon the information in Exhibit 1 anExhibit 2, the value of the embeeoption in Bon4 is closest to: A.nil. B.0.1906. C.0.8789. C is correct. Bon4 is a callable bon Value of issuer call option = Value of straight bon– Value of callable bon The value of the straight bonmcalculateusing the spot rates or the one-yeforwarrates.Value of option-free (straight) bonwith a 1.55% coupon using spot rates:1.55/(1.0100)1 + 1.55/(1.012012)2 + 101.55/(1.012515)3 = 100.8789.The value of a callable bon(par) with no call protection periocannot excee100, thprior higher the bonwoulcalle The value of the call option = 100.8789 – 100 = 0.8789. 这道题V-straight_bon一开始是用SPOT RATE,从第三期往前折算(二叉树方法,只是不用分叉计算),发现出来结果是101.1742和答案100.8788不一样。然后我用forwarrate算一次发现结果就是100.8788,由此联想到,请问二叉树中各期利率是不是forwarrate? 我一直理解为SPOT RATE

The value of a callable bon(par) with no call protection periocannot excee100, thprior higher the bonwoulcalle为什么不会是小于100呢?没有赎回时间限制的callable bon什么一定价值是100呢?
