老师,请问最后一题,我理解是Call option cost=Z-spread — OAS,那call option的OAS越低,call option cost不就越大吗?根据V(callable bond)=V(pure bond)— V(call option cost),call option cost越大,callable bond的价格就会越低,这样理解的话跟答案刚好相反,我是哪里理解错了吗?
The interest rate tree performs two functions in the valuation process: (1) generating the cash flows that are interest rate dependent and (2) supplying the interest rates used to determine the present value of the cash flows.请问这段话中的利率树的第一个功能,cash flow,不是债券自己的特性么,为什么是interest rate dependent呢?

- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
