Whis the mofieration of this bon 2.62 2.85 3.00 2.75 ANSWER: A面值为1000的3年的option-free的债券，coupon rate为10%，YTM为5%，求mofieration是多少？ration=8.38%*1+7.98%*2+83.64%*3=2.75mofieration=2.75/1.05=2.62 助教你好我都快被这问题烦死了😩，之前我问过类似问题，助教回答如果题目没特别指明，那FRM多是连续复利。但是本题就不是连续复利。所以，除了像FRA这种明显用单利去计算的产品，衍生品和债券在题目没有刻意说明怎么复利的情况下，是默认怎么处理呀？可以总结一下吗。。。谢谢！
