What is a bond duration ETF (short vs long duration)?

Bond duration is a measure of how sensitive a bond (or bond ETF) is to changes in interest rates. Higher duration generally means bigger price moves when rates change.

Short-duration bond ETFs tend to have smaller price swings when rates rise or fall, but they often have lower yields. Long-duration bond ETFs can offer higher yield but can drop more when rates rise.

When choosing between short and long duration, match it to your goal. If you want stability and cash-like behavior, short duration can fit better. If you're making a rate bet or want more sensitivity, long duration is more exposed.
