If, for example, you own a bond with a duration of four, then its value will go up about 4% if interest rates fall by a percentage point; the bond will lose about 4% if rates rise by one point.

举例来说，如果你持有的债券久期为4，那么利率下降1个百分点，该债券价值就会上升大约4%；而如果利率上升1个百分点，债券就会贬值4%。

Duration measures the amount of time until a bond matures, and longer-duration bonds fall harder when interest rates rise.
