问题如下:
The value of a swap typically:
选项:
A.is non-zero at initiation.
B.is obtained through replication.
C.does not fluctuate over the life of the contract.
解释:
B is correct.
Valuation of the swap during its life appeals to replication and the principle of arbitrage. Valuation consists of reproducing the remaining payments on the swap with other transactions. The value of that replication strategy is the value of the swap. The swap price is typically set such that the swap contract has a value of zero at initiation. The value of a swap contract will change during the life of the contract as the value of the underlying changes in value.
中文解析:
swap的value在期初为0,但是在合约期内,这个价值是会随着标的物资产的价值的改变而改变的,所以是处于一个波动的状态,所以A和C都是错误的。
我们对swap进行估值时,是将其等效为两个债券的现金流,将未来的现金流折现求净值得到的,是基于一个replication的原理,所以B是正确的。
我理解合约期内value是会波动的,但price不会波动对吧
