问题如下:
When using the Monte Carlo approach to estimate the value of mortgage-backed securities (MBSs), the model should:
选项: use one consistent volatility
measure for all interest rate paths.
use a short/long yield volatility approach.
C.use annual interest rates over the entire life of the mortgage security.
D.ignore the distribution of the interest rate paths used to determine the theoretical value.
解释:
B is correct.
When using the Monte Carlo approach to estimate the value of MBSs, the model should use more than one volatility measure for all interest rate paths. It is very common to use a short/ long yield volatility approach to estimate monthly rates. Although the information regarding the distributions of interest rate paths is oftentimes ignored, it contains valuable information and should be considered.
解释里面最后一句话和D选项不是一样的吗,都是Ignore the distribution of interest rate?
