What are the duration and convexity of a two-year bond that pays an annual coupon of 10% and whose current yield to maturity is 14%? Use $1000 as the face value. A. 1.637 years and 3.3491 B. 1.732 years and 4.0283 C. 1.892 years and 4.2276 D. 1.906 years and 4.3278 此题给出的答案为D,但并没有给出convexity的具体计算过程。 附件截图中的计算公式有三点疑问如下: 1、第一个公式的sigmma-t是如何计算的?麻烦以本题为例. 2、第二个公式是否也是convexity的计算公式?两者有何区别? 3、两个公式均未算出与答案一致的convexity,求解。
