The Fed raised rates a quarter point today. The part that confuses people about bonds:
A rate rise lowers the price of bonds you already own and raises the income on bonds you buy next. Those two effects run in opposite directions, and duration tells you how long the second takes to outrun the first.
A holding with a duration near six years falls roughly 6% in price when rates rise a point, then earns the higher yield from there. If the money is needed sooner than that, the price side dominates. If it's needed later, the income side does.
