Bond 工作表怎么清空呀 我用2ND CE/C和 2ND FV都不行

这道题我算出来当Q是100，000时的profit是740000.和老师上课得出来的不一样

老师，所以只有dividend才会使这两种价值不同。 B,C并不改变American和european option的value是吧？

discretionary是什么意思？为什么会有discretionary和non-discretionary呢？

书后138页 12题 这里freestanding credit derivatives是衍生品投资？ 要记入损益表？ 这个知识点会在衍生里面讲到吗

书后137第11题 这题为何不选A

these figures on the B/S are recorded as at Dec 31, to calculate the current ration=CA/CL, it included installment loan payable of 400(1200/3), which I don't quite understand. these loan payable are due in 3 equal annual payment on June 30, so by Dec 31, it alreay passed the June 30 date, so I dont understand why add 400 payable into the CL?

老师为什么修正久期就是线性关系啊 图中第一题可以再用画图的方式讲一下嘛谢谢啦
