问题如下：
Which of the following statements best describes empirical duration?
选项：
A.
A common way to calculate a bond’s empirical duration is to run a regression of its price returns on changes in a benchmark interest rate.
B.
A bond’s empirical duration tends to be larger than its effective duration.
C.
The price sensitivity of high-yield bonds to interest rate changes is typically higher than that of investment-grade bonds.
解释：
A is correct. A bond’s empirical duration is often estimated by running a regression of its price returns on changes in a benchmark interest rate.
看了其他的提问解答，可以理解C是错的，但是我记得课上何老师说，HYB就像差生，受到周围环境影响更大，这个和C选项说的是一件事还是两件事？我没有太区分清楚
