How to Build a Bond Portfolio

It's been a wild ride in the bond market. Treasury yields have whipsawed over the last two years, with the 10-year Treasury yield touching 5% in October 2023, only to fall to the 3.8% area by the end of August 2024. Investors wondering if they've missed the opportunity to earn attractive yields should keep in mind that yields are still generally higher than they were for the 10-year period following the global financial crisis.

There may be some confusion regarding how to actually invest, given how large and complex the bond market is. Below we'll address four key points about bond investing, ranging from "how" to invest to "why now?"

1. Bonds for income and capital preservation

These are two of the key reasons to own high-quality bond investments. Most bonds make semiannual interest payments that are known in advance based on a percent of the bond's par value. A missed interest payment generally triggers a default for the issuer, whereas stock dividend payments are discretionary and can be raised, lowered, or eliminated based on the outlook for the company. Defaults for highly rated investments tend to be rare, however; default risk is highest for investments with sub-investment-grade, or "junk," ratings.

Bonds also have fixed par values and maturity dates, so barring a default, investors know in advance what they'll receive and when.

Bond prices can still rise and fall in the secondary markets, which might catch investors off guard because bonds are often considered "safe" investments. Bonds have interest rate risk, so their prices can rise and fall with the changing interest rate environment, as the chart below illustrates.

Shown below is the price of a Treasury note that matured in August 2024. It was issued in August 2014 at its $1,000 par value—meaning it was a 10-year note when issued—and matured at its $1,000 par value. As you can see, it was a bumpy ride along the way, illustrating that even high-quality investments like U.S. Treasuries can experience ups and downs. Yet the Treasury note matured at its par value in August 2024, meaning the principal was preserved, while still paying 2.375% annually to bondholders. Holding bonds to maturity can help investors "look through" any potential price changes, as those price increases and decreases are ultimately unrealized. Keep in mind that this illustration is for one individual bond. Bond mutual funds and ETFs generally don't have set maturity dates or par values, so there are additional considerations for investors when deciding what approach is most appropriate.
