The Benefits of a Flexible Core
Published on October 22, 2024
Investment grade bonds have long been synonymous with a “core” fixed income allocation, but we believe a flexible strategy also belongs in most bond portfolios, as managers can adjust their exposure based on market conditions.
Investment grade (IG) bonds have always been the primary option for core fixed income allocations, and on paper the logic is sound. The IG universe is diverse, default risk is minimal, and liquidity is high. Moreover, IG bonds can act as a buffer when equity markets stumble.
However, in the nearly two decades since the Great Financial Crisis (GFC), IG has revealed its limitations – first during the two zero interest rate periods, and more recently during the latest Fed tightening cycle. In each case, investors were reminded that interest rate risk can adversely impact IG returns, even in the absence of credit risk.
In our view, the best way to protect your core IG allocation is to combine it with an actively managed, flexible strategy that can react to changing market conditions in real time. Not only can these types of strategies limit downside when rates are rising, they can pursue higher yielding alternatives when rates bottom out. Traditional, benchmark-oriented strategies are required to invest roughly the same way regardless of the economic environment and/or the relative merits of a particular sector, which leads to predictably negative returns when conditions are unfavorable.
OSTIX: Flexibility Without Stretching
Our philosophy has always been rooted in common sense. We search for the most attractive areas of the market given the conditions – often high yield (HY) bonds – and then we try to find the least risky way to invest there (mostly by shortening duration, but not always). As you can see from the chart below, we significantly ramped up our HY allocation starting in 2009, after the GFC, when the Fed and other central banks committed to zero (and, in some cases, negative) interest rate policies that lasted until 2016. During that stretch, IG bonds were delivering consistently meager returns, and we felt that HY made much more sense. (As an aside, prior to the GFC we were invested in a more balanced mix of HY, IG, and convertibles.) We have remained primarily in high yield bonds since 2009, as we continue to believe they offer a more attractive risk/return profile than investment grade bonds, but, as you can also see, we have reduced our HY exposure during each of the past two Fed tightening regimes.
Source: Osterweis Capital Management. The “Other Fixed Income” category consists of IG bonds, convertibles, preferred stock, Treasurys, private MBS, floating rate bonds, and short-term debt (including HY). Prior to 2016, HY bonds maturing within one year were classified as short-term debt and included in "Other Fixed Income”; thereafter such short-term HY bonds were included in the “High Yield” category. Equities consist primarily of stocks received through corporate actions.
We understand that high yield bonds are not typically associated with a core fixed income allocation, but they have worked well for us because we increase/decrease our exposure based on the economic environment and curate what we believe is a more creditworthy selection of companies from the HY universe. Moreover, we pair our HY bonds with cash and other lower-risk securities to dampen our portfolio volatility in times of market exuberance, thereby softening the potential impact of subsequent market corrections. Because HY bonds generally yield more than IG bonds, we do not have to stretch for yield by extending duration or taking excess credit risk. We have been investing this way for over 20 years, and we have delivered substantially higher returns than the Bloomberg U.S. Aggregate (Agg) since our inception, while keeping our volatility nearly in line with the index.
Not All High Yield Is Junk
In our view, high yield bonds, also sometimes referred to as “junk,” are a largely misunderstood asset class.1 The distinction between an IG bond and a HY bond is determined entirely by its credit rating. If Moody’s and S&P assign a rating above the cutoff (Ba1 and BB+, respectively), a bond is considered investment grade. If not, it is high yield. We have always felt that dividing such a large and dynamic market into two giant buckets is an oversimplification, and we have dedicated ourselves to exploiting the inefficiencies it creates.
Setting aside the issue that a rating is merely one subjective opinion, roughly 50% of the HY index is BB and 50% of the IG corporate index is BBB. In other words, approximately half of each universe is on the border, which means they have fairly similar default risk.

The table below shows the annualized default rates of each ratings grade over 5-year, 10-year, and 15-year periods. While the default risk is a little higher for BB than for BBB bonds, the absolute level of risk is still relatively low. Obviously, the risks increase as you move down the ratings scale, but statistically speaking a high-quality HY bond is not substantially different from a low-quality IG bond.
The last row of the table shows the default rates for OSTIX. As you can see, our 5-year rate is comparable to the BB category, but our 10-year rate is roughly half the BB rate, and our 15-year rate is only 11 basis points higher than the BBB rate. In other words, over the long run, the credit risk of our portfolio, which has been primarily high yield bonds, is similar to an investment grade portfolio.

In addition, the correlation between a bond’s spread, which is the market’s real-time assessment of its credit risk, and its rating is fairly low. Said differently, a BB bond, which is at the top of the HY spectrum, and a CCC bond, which is at the bottom, can have similar spreads, suggesting that once a bond is trading in the open market, most investors do not place much weight on its rating. As you can see in the chart below, every ratings category except the very lowest has a cohort of bonds trading at spreads between 200-500 basis points.

In summary, we believe that there is strong empirical evidence that ignoring HY and dismissing it as “too risky” for a core allocation is essentially a missed opportunity. In our view, leaning into HY, but doing so in a strategic and selective manner, is among the smartest decisions a fixed income investor can make. Because the asset class is so stigmatized, knowledgeable investors can exploit market inefficiencies that others are simply overlooking.
Aligned Incentives Are the Key
Perhaps our belief in the benefits of HY bonds is rooted in our experience. For over two decades we have been investing in the space, and during that time we have developed an approach to evaluating borrowers that has seldom let us down. Like all managers, we strive to find companies with strong fundamentals and good credit metrics (e.g., coverage ratios, leverage ratios, healthy free cash flow), but we have also always looked for something else that we believe is at least as important. Namely, we are looking to lend money to companies whose incentives are aligned with our own.
For us, it is essential that the borrowers are using leverage strategically and transparently, and that they invest directly into their business, rather than pay themselves large dividends or repurchase their own shares. The classic example is a company that borrows money to build a new factory or expand its geographic footprint – these kinds of investments give the business a chance to grow in the future, which increases its enterprise value and improves the likelihood it will repay its debts in full. In short, we are looking for companies that we believe are good stewards of capital, as they will borrow responsibly and prioritize repayment.
In addition, these types of businesses tend to incorporate stronger covenants into their bonds, which gives us additional protections beyond the company’s verbal promise to repay. Also, they are generally more inclined to allow direct access to their executive teams. This not only helps us conduct stronger due diligence, as we can ask management questions about their business plan, but it also enables us to provide strategic advice in situations where they may need guidance navigating the capital markets.
When we are evaluating a new position, we have found these factors are much more important than a bond’s credit rating, although we tend to be underweight CCCs, as they do not usually meet our investment criteria.
Avoid the Herds
Another technique we use to manage risk is to avoid the most crowded areas of the market, as securities with strong demand are often not particularly attractive. For example, larger bonds that are included in a fixed income index tend to offer below-market yields, as passive funds are essentially required to buy them in order to match their benchmark. As a result, issuers know their bonds will be purchased even if the coupons are below market.
Conversely, sponsor-backed leveraged buyouts (LBOs) have tended to offer competitive yields, which makes them highly sought after, but the terms of the deals are usually quite unfavorable for investors. LBOs are typically led by private equity companies that saddle the underlying business with substantial levels of debt, and they frequently use the proceeds to pay themselves generous dividends. The net result is a company that is left with significantly higher debt service but no improvement in its ability to pay, as they generally have the same base of operations as before the deal.
A Track Record of Success
Our goal has never been to beat a specific index – it has always been to invest in the areas of the market with the most attractive risk/return profiles. Because we have been consistently overweight HY for most of the past two decades, we have substantially outperformed the Agg over that stretch. At the same time, because our HY exposure has always been less than 100%, and has fluctuated according to the market conditions, we have lagged the ICE BofA HY Index, but with substantially less volatility. We have, in essence, deliberately pursued a middle ground, as this allowed us to increase our returns without significantly increasing our risk. As you can see from the chart below, our performance lies almost directly between the IG and HY indices, and our drawdowns during market selloffs are substantially less severe than those of the HY index.

Final Thoughts
In our view, investors have been thinking too narrowly about their core fixed income allocation for too long. Interest rate cycles have predictable results for investors of traditional core funds, which generally track the Agg. Those funds will almost always struggle when interest rates rise, as their managers have limited options available to protect their portfolios. Likewise, they will struggle when the Fed cuts rates aggressively, as they will not generate enough yield to deliver meaningful returns.
An actively managed, flexible strategy, on the other hand, has the ability to move into sectors that are suited to a particular environment (and vice versa), whether the change is triggered by an interest rate move or a change in the credit cycle. As we have demonstrated over the past 20+ years, being nimble in the fixed income market is more important than adhering to the orthodoxy around what makes up a “core” fund.

The Fund was rated 4 Stars against 598 funds Overall, 4 Stars against 598 funds over 3 Years, 5 Stars against 563 funds over 5 Years, 4 Stars against 425 funds over 10 Years in the High Yield Bond category based on risk-adjusted returns as of 9/30/24.
The Morningstar Rating™ for funds, or “star rating,” is calculated for mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product’s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period has the greatest impact because it is included in all three rating periods.

The Osterweis Strategic Income Fund may invest in debt securities that are un-rated or rated below investment grade. Lower-rated securities may present an increased possibility of default, price volatility or illiquidity compared to higher-rated securities. The Fund may invest in foreign and emerging market securities, which involve greater volatility and political, economic and currency risks and differences in accounting methods. These risks may increase for emerging markets. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. Small- and mid-capitalization companies tend to have limited liquidity and greater price volatility than large-capitalization companies. Higher turnover rates may result in increased transaction costs, which could impact performance. From time to time, the Fund may have concentrated positions in one or more sectors subjecting the Fund to sector emphasis risk. The Fund may invest in municipal securities which are subject to the risk of default.

Yield is the income return on an investment, such as the interest or dividends received from holding a particular security.
Spread is the difference in yield between a risk-free asset such as a Treasury bond and another security with the same maturity but of lesser quality.
A basis point is a unit that is equal to 1/100th of 1%.
Investment grade/non-investment grade (high yield) categories and credit ratings breakdowns are based on ratings from Standard and Poor’s, which is a private independent rating service that assigns grades to bonds to represent their credit quality. The issues are evaluated based on such factors as the bond issuer’s financial strength and its ability to pay a bond’s principal and interest in a timely fashion. Standard and Poor’s ratings are expressed as letters ranging from ‘AAA’, which is the highest grade, to ‘D’, which is the lowest grade. A rating of BBB- or higher is considered investment grade and a rating below BBB- is considered non-investment grade. Other credit ratings agencies include Moody’s and Fitch, each of whom may have different ratings systems and methodologies.
Leverage ratio is a financial metric that helps investors assess how indebted a company is. A lower number is more desirable than a higher number. There are several ways to compute leverage, but one common approach is to divide the company’s total outstanding debt by its trailing 12-month profits.
Free cash flow represents the cash that a company is able to generate after laying out the money required to maintain and expand the company’s asset base. Free cash flow is important because it allows a company to pursue opportunities that enhance shareholder value.
A leveraged buyout (LBO) is the acquisition of another company using a significant amount of borrowed money (bonds or loans) to meet the cost of acquisition. The assets of the company being acquired are often used as collateral for the loans, along with the assets of the acquiring company.
The Sharpe ratio is the difference between the annualized portfolio return and the annualized risk-free return, divided by the annualized standard deviation of the portfolio returns. It represents the additional amount of return that an investor receives per unit of increase in risk.
Standard deviation (annualized): This measure of dispersion represents the degree to which an investment’s returns vary around a mean. The greater the standard deviation, the more volatile an investment’s returns were during the period measured.
