An investor's guide to high yield bonds

Fixed income is a broad universe where investments come in a variety of guises. Among other factors, fixed income securities – often referred to as bonds - vary in terms of lifespan, yields on offer, and of course risk profile. As with all investments, the higher the potential return on offer, the higher the inherent risk involved, and bonds are no exception. The general rule of thumb dictates that government-issued bonds sit at the lower end of the risk spectrum while so-called high yield, or sub-investment grade bonds, inhabit the riskier end of the credit spectrum.  

Here, we explain what bonds are, what drives their value and why investors should potentially consider the high yield sector.

Why invest in bonds?

Bonds are essentially ‘IOUs’ issued by corporations and governments looking to raise money. When you invest in a bond you are lending your money for a fixed period - and in exchange, you earn a regular fixed rate of interest known as the coupon. When the bond’s term reaches maturity, the original investment, or principal is paid back to the bondholder.

Bonds can either be invested directly, or indirectly through a bond fund, which may hold a variety of fixed income assets. Individual investors are less likely to invest directly in individual bonds given the typically prohibitively high minimum investment amounts required, however. As such the vast majority will invest via a fund where a professional fund manager will pick and choose bonds to hold on behalf of investors.

The main risk associated with bond investing is that the borrower may get into financial trouble and subsequently be unable to meet interest payments, or the issuer goes bust and is unable to repay the bond. However, as a rule of thumb, bonds tend to be less risky or volatile than equities (i.e. shares). This is because creditors (bond investors) sit at a more senior level in a company’s capital structure than owners (equity investors). If a firm fails, debt holders are first in the queue for any recovery of the firm’s assets.

Interest rates

If investors think rates will rise, then bond prices typically fall in value as new bonds coming to the market will offer higher coupons, reflecting the higher interest rate. Equally if interest rates fall the reverse is true – a bond’s value will rise, but its yield will drop. Bear in mind that falling yields are good news for bond investors – it means the value of their portfolio is rising; rising yields are bad news, as the value of the bonds they hold is falling.

Duration

A bond's lifespan – how long until the bond matures - is always a major consideration. Bonds with longer maturities, such as 10-20 years, are considered riskier, as long-term interest rate movements are unpredictable. Their prices are also more sensitive to changes in interest rates. The price of a 30-year bond will move more for a 1% change in interest rates than the price of a three-year bond. (Duration measures the sensitivity of bond prices to changes in interest rates). Additionally, inflation will have an impact on the principal - $100m today will be worth more than $100m in 25 years’ time. High yield bonds come with shorter maturities than many investment grade bonds (typically less than 10 years) and as such tend to have relatively lower duration. This means high yield bonds can potentially be less exposed to interest rate risk than most investment grade strategies.

Why investors should consider high yield bonds

High yield bonds are among the higher income investment offerings. They are generally issued by companies which could be more capital-intensive and may have higher levels of debt – and therefore could be seen as a higher credit risk. But while they’re riskier than government and corporate investment grade bonds, they offer investors the potential for much higher rates of income. This higher income stream has the potential to offset the higher risk of principal loss. Active strategies that can minimise principal loss while still maintaining a higher income stream can potentially lead to outperforming results.

The performance of high yield bonds also tends to have lower correlation to other sectors within the fixed income market, so can provide important diversification to a broader bond portfolio and as highlighted, they can be less sensitive to interest rates. In addition, there is also the potential for capital growth. Like equities, high yield bond prices can increase because of the issuing firm’s improved performance or a wider economic upturn. In addition, the typically higher income component of high yield bonds means that they are generally less volatile than equities, but their performance is more correlated with stocks than that of longer-duration less risky investment grade corporate bonds.

The high yield bond market was born in the US and the world’s largest economy remains the largest and most liquid market. But today there is a wider, global high yield market offering potential benefits such as the diversification of Europe or the stronger growth potential of emerging markets.
