How to consider a B/BB US high yield strategy within a portfolio

  • 05 December 2023 (7 min read)

The US high yield market has performed well in 2023, offering investors attractive all-in yields and a healthy fundamental backdrop during a year that has been marred with uncertainty and surprises. Many high yield companies came into 2023 having taken advantage of cheap borrowing costs from previous years. They have, therefore, largely been able to weather the rising rates environment without needing to refinance. In many cases they have also used free cash flow to pay down debt and de-lever. This can be seen by the fact that both high yield leverage and coverage ratios are coming off historically strong levels, albeit starting to deteriorate towards the end of 2023 as the ‘higher for longer’ interest rate environment drives dispersion higher. This is particularly seen amongst more levered, capital-intensive companies that do not have the cashflow to absorb significant interest rate increases.

Although this increasing dispersion is leading to a pick-up in default activity, driven particularly by a larger proportion of distressed exchanges and borrowers who also have a loan component in their capital structure which is more immediately impacted from higher rates, we continue to believe that corporate fundamentals remain robust enough to prevent the default rate of the US high yield bond market from increasing to a level significantly higher than its long-term average (3.3% according to JP Morgan).

In this environment, we think that a higher quality high yield strategy offers compelling opportunities to investors who are seeking a yield pick-up from investment grade but remain concerned about the macro environment and want to avoid the part of the high yield market which has historically carried the most default risk. Based on our outlook for the economy and current valuations, we believe that this portion of the US high yield market can deliver attractive total returns over the next 12 months and beyond.

Understanding the high yield credit spectrum

For some investors, accessing the full spectrum of the high yield market is not possible due to capital risk or regulatory requirements. For others, it may be possible, but concerns around default rates may dictate a preference for a higher quality approach. An option for such investors may be to take a more selective approach to high yield and invest via a B/BB strategy rather than avoid high yield altogether.

This selective approach to high yield investing does not have to feel like a compromise. Firstly, over the past few years, there have been a wave of upgrades within the US high yield market1  and downgrades from investment grade to BB.2  This has resulted in the US high yield market, which numbers 880 issuers3  in total, moving up in quality: today just 11% of the broad market is rated CCC and below, compared to 49% rated BB and 40% rated B. As the chart below demonstrates, although the lowest rated part of the market has historically always accounted for the smallest component by market value, at more distressed points of the cycle we have seen the amount of CCC and below securities rise as high as 26% in 2009 after the Global Financial Crisis and 15% in 2017 after the wave of energy company downgrades. The historically low percentage of CCC securities in the market today is a sign of strong fundamental strength, but also means that B/BB investors still have access to around 90% of the overall market in market value terms.

Breakdown of the US high yield market by credit rating buckets


Despite representing the smallest rating bucket by market value, the CCC and below component accounts for the largest proportion of default activity within the US high yield market. We believe that the ‘truest’ way of measuring the credit rating spectrum is on an exponential rather than linear scale, with the credit curve acting as an indicator of underlying default risk, measured in spread (basis point) terms. Credit spreads increase exponentially down the curve to compensate for the underlying credit risk, highlighted by the chart below.

This chart, which plots the average spread of different rating buckets across the full US credit spectrum over a 20-year period, shows that the spread differential between BBB and BB rated securities is 154bps, whereas the difference between B and CCC rated securities is higher at 493bps. Therefore, we may consider that, despite BBB and BB securities being differentiated by rating agencies in terms of ‘investment grade’ versus ‘high yield’, they have more in common than BB securities have with CCC securities.

This exponential credit risk is reflected in the fact that the bulk of historical high yield default activity has occurred within the CCC rated bucket. Looking at the 25-year average default rate the largest component of this is CCC/split CCC, tracking at around double the overall high yield default rate of 2.99% for this period:

Investing involves risk and past performance does not guarantee future results. No assurance can be given that the strategy will be successful or achieve its objectives.

That is not to say that we do not like investing in CCC rated securities. To the contrary, we find plenty of opportunities in improving CCC rated credits that may be penalised by rating agencies for having higher leverage and lower asset values, but which we believe have sound fundamentals and hence less business or operational risk. We feel comfortable holding these credits, however believe that robust, prudent credit analysis and active management are required to ensure that we try to avoid losses and defaults.
