The higher the duration of a bond, the more sensitive it is to yield changes. Conversely, the lower the duration of a bond, the less sensitive it is to yield changes.
The modified duration of a bond can be thought of as the first derivative of the relationship between price and yield:

- P− is the price of the bond from a decrease in yield ...
