为什么债券价格900 面值就是1000？

老师，在这一页。N是整数么？如果我投资了6个季度（一年半），这里的N=1.5 么？

R46 原版书第21，22题解析没太，麻烦再解释一下 谢谢

不理解为什么高峰必然带来肥尾，从图中看不出来啊……

不理解为什么高峰肥尾代表极值出现频率大？图里面靠近均值那部分应该出现更频繁吧？末端不是数值越来越少么？

老师讲得有点跳，好混乱呀

RMBS和CMO的区别是什么？

33分40秒第五点卡顿了，第五点是什么意思

In my opinion, the gain/loss of the 0.74 GBP/EUR forward arrangment shall be the difference of higher price to sell EUR and lower price to sell EUR, not the higher price to sell EUR and lower price to buy EUR.

Key difference is that i use 0.7356 to sell EUR into GBP. Reason is that the firm can either sell EUR at 0.7356 for GBP or sell EUR at 0.74 for GBP, the difference is the vaue of the forward , so future gain is 5,000,000*(0.74-0.7356)=22,000, PV is 21,968 (discounted by (1+0.58%*1/4))
