How to Use the Bond Compass

Read the market, understand duration, and compare fixed income choices.

Choosing a bond involves more than finding the highest yield. A short Treasury bill may offer flexibility, while a longer bond can lock in income but expose its market price to larger swings. The Bond Compass brings several signals into one place to help you assess that trade-off.

The Compass displays a score from 0 to 100 and places it in one of five zones, ranging from cash and short-term securities to longer-duration bonds. A lower score favors keeping interest-rate exposure shorter. A higher score favors considering more duration. The score is a framework for comparing the current environment, not a prediction of the next bond-market move or a recommendation to buy a particular security.

First, what is duration?

Duration measures how sensitive a bond's price is to changes in yield. A bond with higher duration will generally gain more value when its yield falls and lose more value when its yield rises. As a rough illustration, a bond with a duration of seven years would change in price by about 7% for a one-percentage-point move in its yield, in the opposite direction. That is a price estimate, not a total-return forecast: income, changes in credit spreads, and other factors also matter. FINRA explains the relationship between duration and interest-rate risk.

Duration is related to maturity but is not identical to it. The cash flows, coupon, yield, and any call features can change a bond's sensitivity. This distinction helps explain the Compass: moving from a short-duration zone to a long-duration zone means accepting more potential price movement in exchange for greater exposure to yields available for a longer period.

How the reading is built

The Bond Compass combines seven indicators. Each receives a score from 0 to 100, and its contribution to the overall reading equals its score multiplied by its assigned weight. The weighted contributions add up to the final score.

The three Fed-related inputs account for 55% of the reading. They give the greatest weight to the direction of market-implied policy rates and to changes in those expectations. The yield curve, credit spreads, and bond volatility together account for 30%. The remaining 15% comes from the ten-year TIPS real yield, an anchor for the level of inflation-adjusted income available in the market.

Those inputs answer different questions. If markets begin pricing lower policy rates, a longer-duration bond may become more attractive, but that signal deserves context. The yield curve shows how rates differ across maturities; credit spreads show what investors are paid for taking corporate credit risk; and the MOVE Index helps reveal whether interest-rate uncertainty is elevated. A higher real yield can make locking in an inflation-adjusted rate more appealing, even when the anticipated Fed path alone gives a mixed signal.

The table labeled “What's driving this reading?” shows the raw market value, normalized indicator score, weight, and contribution for each input. The raw value and score serve different purposes. A 2.6% real yield, for example, is a market observation; the associated score is the Compass's interpretation of that observation under its methodology. A contribution of 15 points from a 15%-weighted indicator scored at 100 means that indicator adds its full possible weight to the composite. The parenthetical percentage alongside a contribution shows its share of the current total, rather than its fixed model weight.

What the five zones mean

The gauge uses plain-language duration labels, including Medium Duration, while the detailed zone guide calls the middle band Hold the Middle. Both point to the same general idea: balancing current income against the price sensitivity of extending further out on the curve. The zones are guideposts rather than precise portfolio allocations. A reading near a boundary should not be treated as an automatic instruction to trade.

How to use the Compass in practice

Start with the dated reading. Check the score, zone, and “as of” date. The date matters because market prices and rate expectations can change. The short commentary beside the gauge explains the day's reading in ordinary language, but the underlying indicator table gives you a clearer view of what is driving it.

Look at the strongest and weakest contributions. A high overall score can come from strong real yields even if the market sees little chance of an immediate Fed cut. Looking below the headline score helps you distinguish attractive starting yields from a shift in rate expectations. It also helps you judge how much of the reading might change if one input moves.

Compare instruments that fit your horizon. The recommended-instruments table lists examples for the current zone, along with yield, risk, tax treatment, and liquidity. Treat these as candidates for comparison, not interchangeable investments. A Treasury, CD, municipal bond, and investment-grade corporate bond may all offer similar stated yields while differing in taxes, credit exposure, access to your cash, and sale price before maturity. Confirm the quote's date and yield definition before comparing securities; a coupon rate, yield to maturity, yield to worst, and CD annual percentage yield do not necessarily describe the same thing. FINRA explains common bond yield measures.

Match the choice to when you need the money. Funds needed soon generally warrant more attention to principal stability and liquidity than a long-horizon allocation. If you may sell before maturity, consider how a change in market yields could affect the sale price. For a callable bond, review the possibility that the issuer repays it early. For a corporate or municipal bond, examine the issuer's ability to pay. Investor.gov outlines bond credit risk, and its municipal-bond guidance also discusses call, interest-rate, and liquidity risk.

What the Compass cannot tell you

Market-implied Fed expectations can change quickly and do not guarantee what the Fed will do. The Fed's short-term policy rate also does not control every bond yield: long-term Treasury yields and credit spreads can move differently. That means a bond can lose value even if a Fed cut occurs, and a high Compass score cannot guarantee a positive return on a long-duration position.

The Compass also cannot know your tax bracket, cash needs, existing bond holdings, or tolerance for temporary price declines. Use its score to understand the current duration trade-off, inspect the indicators that produced the reading, and then compare securities against your own investment horizon and after-tax objectives.
