Bond Portfolio Strategies: Barbell vs. Bullet

Beyond laddering, here are two other maturity strategies worth knowing for a bond portfolio.

The barbell strategy

A barbell strategy concentrates bond holdings at the short and long ends of the maturity spectrum while holding little or nothing in between. The name comes from how the maturity distribution piles up at both extremes, resembling the two weighted ends of a barbell.

Characteristics of a barbell portfolio

By combining short-term bonds, which offer liquidity and flexibility to react quickly to interest-rate changes, with long-term bonds that typically offer higher yields, a barbell aims to capture benefits from both ends of the curve at once.

The bullet strategy

A bullet strategy concentrates bond holdings around a single target maturity rather than spreading across the curve. The name evokes a bullet converging on one point, unlike a barbell's split at two extremes.

Characteristics of a bullet portfolio

A bullet strategy is well suited to matching a bond portfolio's maturity to a known future cash need, such as a child's tuition payment or a planned retirement date, making the timing of cash flow relatively predictable.

Comparison with a laddering strategy

A laddering strategy spreads bond holdings evenly across many maturities, while both the barbell and bullet strategies deliberately concentrate holdings at specific points along the maturity curve instead of spreading them evenly.

How to choose between them

Choosing among these strategies comes down to weighing your outlook on future interest rates, when you'll actually need the cash, and how much liquidity you want to keep on hand. There's no single right answer; the best fit depends on your personal circumstances and goals.

None of these strategies is a bet-free way to avoid interest-rate risk

Whichever maturity structure you choose, a bond portfolio remains exposed to changes in interest rates and to the credit risk of whatever issuers you hold; a barbell, bullet, or ladder shapes how that exposure is distributed across time rather than eliminating it. Pairing any of these structures with an understanding of yield-to-maturity and duration gives a fuller picture of how the portfolio might behave as rates move.

Frequently Asked Questions

Is the barbell or the bullet strategy generally the better choice?

Neither is universally better; the right choice depends on your interest-rate outlook, when you will need the cash, and how much liquidity you want on hand, so it comes down to individual circumstances rather than one strategy being objectively superior.

Can investors with smaller amounts of money use these strategies?

Building either strategy from individual bonds across multiple maturities can require significant capital. Combining bond ETFs with different target maturities is one way smaller investors can approximate a similar structure with less money.
