同学你好,最后一笔本金就是债券的面值。

这个过程是这样的,是指我们用股票的收益去交换一个债券的收益。或者也可以理解为我用我股票的头寸去交换到了一个债券的头寸。签订互换合约的时候,股票的价值=债券的价值,整个合约的value=0.

作为这个manager来说,他每期就收到债券在当期的收益,支出股票在当期的收益。对于manger来说,他收到的净现金流就是二者之差。实际上在每期互换合约计算的时候,只要结算净现金流就好了。

比如manager的净现金流是-10块钱,那就是manager 给对方10块钱,如果manager的净现金流是10块钱,那就对方给manager10块钱。

求value的时候,就是相当于我们看下债券的价值现在是多少,股票的价值是多少,二者之差就是签这份合约的value。债券的价值就是未来现金流折现求和。而股票的价值就是当前股票的价格乘以份数。所以最后一笔现金流就是债券的面值。
