American Funds Multi-Sector Income Fund Class 529-F-3 CMBQX

The Capital Group multisector fixed-income strategy, known in the US as American Funds Multi-Sector Income, is an appealing option for investors who want a vehicle that majors on US corporate credit. Morningstar is initiating coverage with Above Average People and Process ratings.

The approach here is vintage Capital Group, combining in a complementary manner specialist insights, team collaboration, and individual accountability for the strategy’s six named managers. All of this is done in service of an income-oriented, credit-heavy mandate that is otherwise flexible. Its portfolio blends to varying degrees high-yield bonds, investment-grade corporates, emerging-market debt, and securitized credit, while leaving room for opportunistic allocations to other parts of the market if they become attractive.

In line with Capital Group’s signature multimanager structure, experts in each of the strategy’s four primary asset classes independently oversee a separate sleeve of the strategy devoted to that asset class, except for principal investment officer Damien McCann. His 35% to 40% slice of the portfolio, the largest of the sleeves, invests across the asset classes and has a big impact on how the strategy differentiates itself from its customized benchmark. That benchmark is weighted 45% in the Bloomberg US Corporate High Yield 2% Issuer Capped, 30% in the Bloomberg US Corporate, 15% in the JP Morgan EMBI Global Diversified, and 10% in a combination of the Bloomberg CMBS Ex-AAA and Bloomberg ABS Ex-AAA indexes, with those weightings serving as the strategy’s neutral allocation for each asset class.

Even with all its flexibility, the strategy’s corporate credit leanings are apparent from comparing the US mutual fund to its multisector bond Morningstar Category peers. The combined weighting of USD-denominated high-yield bonds and investment-grade corporates, including the impact of credit derivatives, has typically ranged from about 60% to 70% of assets since the strategy’s March 2019 inception, versus 35% to 45% for the peer median.

Although the strategy can and does buy protection through index-level credit default swaps, its portfolio is nonetheless prone to struggle in spread-widening environments, as in early 2025. Amid heightened tariff concerns between Jan. 22 and April 7, 2025, high-yield bond spreads widened more than 200 basis points as relevant Treasury yields declined around 50 basis points. Over that period, the US mutual fund’s R6 shares lost 1.34%, which was close to a bottom-decile showing versus distinct peers.

The strategy, though, has a competitive long-term record, thanks to its ability to take advantage of opportunities through a market cycle. It rebounded with top-quintile results for the rest of 2025, for example, and finished that year just ahead of the category median. In fact, in the five full calendar years since the US mutual fund became publicly available on May 1, 2020, it has finished near or above the peer median in four of them, including a top-decile finish in 2023.

Differences in exposures to leveraged loans and commercial mortgage-backed securities can lead to performance divergences between the strategy’s global vehicles in any given year, but over the long haul the results across the vehicles, adjusted for currency effects, should be close.

The Capital Group multisector fixed-income strategy, whether the US mutual fund American Funds Multi-Sector Income or its Canadian, European, and Australian vehicles, merits an Above Average Process Pillar rating.

This US-focused strategy’s approach is vintage Capital Group, combining in a complementary manner specialist insights, team collaboration, and individual accountability. All of this is done in service of an income-oriented, credit-heavy mandate that is otherwise flexible. Indeed, its portfolio blends to varying degrees high-yield bonds, investment-grade corporates, emerging-market debt, and securitized credit, while leaving room for opportunistic allocations to other parts of the market if they become attractive.

In line with Capital Group’s signature multimanager structure, experts in each of the strategy’s four primary asset classes independently oversee a separate sleeve of the strategy devoted to that asset class, except for principal investment officer Damien McCann, whose sleeve invests across the asset classes. The strategy gauges itself against a customized benchmark, weighted 45% in the Bloomberg US Corporate High Yield 2% Issuer Capped, 30% in the Bloomberg US Corporate, 15% in the JP Morgan EMBI Global Diversified, and 10% in a combination of the Bloomberg CMBS Ex-AAA and Bloomberg ABS Ex-AAA Indexes, with those weightings serving as the strategy’s neutral allocation for each asset class.

While good bond-picking through a market cycle is a priority for each manager, the strategy aims to take advantage of bond sector-level mean reversion in credit spreads, especially in McCann’s generalist sleeve. He will tilt the overall portfolio toward high-yield bonds, for example, when their spreads widen relative to historic norms and tilt away from them when their spreads narrow, often through index-level credit default swaps.

The strategy’s remit is consistent across its global vehicles, but domicile requirements often lead to modest differences. European regulations preclude holding single-asset, single-borrower CMBS and leveraged loans, for example, which means the Australian managed fund also lacks these exposures as it feeds into the European version of the strategy.

The strategy tethers the portfolio’s interest rate sensitivity (as measured by duration) to that of its customized benchmark. Initially, the strategy could vary its duration by up to 1 year versus that index, but beginning in 2021’s second half could differ by up to 2 years. Since its March 2019 inception, the strategy’s duration has ranged from 4 to 6 years, versus about 3.5 to 4.5 years for the US multisector bond category median over the same period.

In all its vehicles, the strategy leans massively toward US corporate credit. The combined weighting of high-yield bonds and investment-grade corporates, including the impact of credit derivatives, has typically ranged from about 60% to 70% of assets throughout the strategy’s history. In fact, even at its since-inception low of 47.5% in February 2020, the US mutual fund’s total high-yield and investment-grade corporate stake was still then one of the multisector bond category’s highest.

True to its flexibility within the confines of a credit-heavy approach, portfolio exposures can shift dramatically along with spreads. When option-adjusted spreads for the ICE B of A US High Yield Index widened at one point to more than 1,000 basis points between the end of February and April 2020, the managers increased their combined stake in high-yield bonds and investment-grade corporates by 28.6 percentage points to about 76%, with most of that increase coming in high-yield exposure, including selling protection through index-level credit default swaps. Similarly, in October 2023 the strategy sold protection to add about 7 percentage points of credit exposure as high-yield-bond spreads widened beyond 450 basis points and closed that position by the end of the year as spreads contracted more than 100 basis points.

Amid changing spreads, the strategy’s north star remains the weightings of its customized benchmark. The June 2026 portfolio of the US mutual fund was about 5 percentage points light in high-yield exposure versus this benchmark and about 4 percentage points overweight in securitized debt, thanks to a roughly 7.5% stake in CMBS. The European and Australian versions of the strategy were then closer to a neutral 10% weighting in securitized, largely because they had minimal CMBS exposure.

The strategy takes more credit risk than most rivals. Between its March 2019 inception and mid-2026, the strategy has on average allocated about 46% of its assets apiece to investment-grade and below-investment-grade debt, with another 5% or so in unrated debt and the balance of the rest in cash. That’s several percentage points more junk bond exposure than the multisector bond category median and represents an edgier profile against peer norms in other parts of the globe, such as Australia’s unconstrained fixed-income category.

Defaults can and do occur within the portfolio, though individual positions in defaulted companies tend to be modest. Entering 2025, for example, the US mutual fund had about 20 and 10 basis points of exposure, respectively, to the USD-denominated bonds of the Brazilian petrochemicals business Braskem and the Brazilian energy company Raizen. Raizen defaulted on its debt in March 2026 and Braskem in June 2026. Both companies are now negotiating with creditors like Capital Group in the courts as their debt trades around half its face value.

Capital Group’s multimanager system helps to handle the roughly USD 35 billion of combined assets in this US-focused multisector fixed-income strategy, whose vehicles span the globe, and its close sibling, Capital Group US Multi-Sector Income ETF. The strategy receives an Above Average People Pillar rating because of that system’s strengths as well as the investment team’s ability, experience, and fund ownership.

As principal investment officer, Damien McCann has the biggest impact on the strategy. He is the only named manager with a generalist remit to invest across the strategy’s asset classes, and his 35% to 40% slice of the portfolio is the largest of its separately run sleeves. The strategy’s five other named managers each run one of those sleeves, consisting of around 8% to 15% of assets apiece, in line with their expertise and individual style. Shannon Ward and Sandro Lazzarini are high-yield experts with distinct approaches as Lazzarini’s sleeve tends to hold about one-fourth fewer issuers and to take on greater credit risk. Scott Sykes is an investment-grade corporate specialist, Xavier Goss a securitized expert, and Robert Burgess an emerging-market debt authority.

Each manager has extensive experience. Lazzarini, the relative industry newcomer, already had around eight years of experience when he joined Capital Group in 2015. Burgess and Ward are the most experienced managers. They both started in the industry in the 1990s, though they joined Capital Group in 2016 and 2017, respectively. McCann is a homegrown talent who started in the industry and at the firm in 2000. Sykes had around four years of experience when he joined Capital Group in 2005 and Goss started at BlackRock in 2003 before coming to Capital Group in early 2021.

The strategy draws on a deep bench of veteran analysts. As of mid-2026, Capital Group’s nearly 60 fixed-income analysts had on average been with the firm about 7.5 years and in the industry for about twice that time. Since the strategy does not have an analyst-led research portfolio as one of its sleeves, the managers here look to the research portfolio of other strategies for analysts’ bond picks and the sizing of those picks, such as the US mutual fund American Funds American High-Income Trust for high yield.

Alignment with investors through manager ownership is significant. McCann invests at least USD 2 million combined in the strategy and its ETF sibling; Ward, Lazzarini, Sykes, and Goss each have at least USD 200,000 together in the two; and Burgess invests at least USD 100,000 in the strategy.

Capital Group stands out from the pack as it enhances capabilities around strong core competencies. It earns a High Parent rating.

Since 1931, Capital Group, parent of American Funds, has thoughtfully built out capabilities to become one of the world’s largest asset managers, managing more than USD 3 trillion dollars. Building on the success of its long-term-oriented, multiple-manager system for global equities, the firm has developed robust fixed-income and multi-asset units, each managing more than USD 500 billion. In January 2026, as part of its periodic review of its now five distinct research organizations, Capital Group implemented changes to its equity investment subsidiaries. This exercise resulted in most equity strategies having at least one portfolio manager change, but according to the firm, it better balances each of Capital Group’s three equity groups in terms of investment breadth and helps the firm better align leadership opportunities across the groups. These kinds of shifts have occurred before, with the last coming in 2018.

Capital Group has also turned its attention to some modern opportunities. To address public/private market convergence trends, it launched in April 2025 two semiliquid funds with private market giant KKR. In keeping with its signature portfolio management approach, it splits those funds into multiple sleeves, which are managed independently by distinct managers at each firm. Capital Group plans to deepen this relationship with target-date and model portfolios, as well as public/private equity funds. On the other end of the spectrum, although the firm is firmly dedicated to active management, it has also acknowledged investor preference for passive investing and has thus partnered with indexing stalwarts Vanguard, BlackRock, and Schwab on active/passive models. Capital Group’s proven investment prowess, strong reputation among investors, and scale mean it can be selective with its partnerships.

In addressing another recent trend, since early 2022, the firm has launched more than 25 active exchange-traded funds globally, most of which are distinct, but several are similar to some of its legacy American Funds mutual funds. Unlike some of its peers, though, it has not filed for SEC exemptive relief to offer ETFs as a share class.

That’s a lot of change for such a storied and sizable firm, but Capital Group has a long history of serving investors well.

The strategy as represented by the US mutual fund has a competitive record. It launched on March 22, 2019, but did not become publicly available until May 1, 2020; since that public debut, its R6 shares’ 4.96% annualized gain through August 2026 beat the Bloomberg US Universal Index category benchmark by 4.28 percentage points and ranked in the top half of nearly 80 distinct multisector bond peers measured by their cheapest share class. Volatility-adjusted results were even better. The R6 shares’ information ratio (a risk-adjusted measure of excess return relative to excess standard deviation) versus the Bloomberg US Universal Index ranked near the category’s top quintile.

Consistency relative to its multisector bond rivals has been a strength for the US mutual fund. In the five full calendar years since it became publicly available, it has finished near or above the peer median in four of them, including a top-decile finish in 2023. That year, adding exposure to high-yield bonds through index-level credit derivatives as spreads widened in October and then reducing that exposure as spreads contracted contributed to the R6 shares’ 11.01% gain, 2.32 percentage points better than the peer median.

Duration was a big culprit in the US mutual fund’s bottom-quartile results amid rising interest rates in 2022, its worst calendar-year showing so far. Although the fund’s 4.03-year duration in January was then nearly 2 years shorter than its customized benchmark’s, and thus as short as the strategy will go relative to that benchmark, it was still longer than the 3.8-year peer median duration at the time. The strategy’s duration remained half a year to a year longer than the peer median for the rest of 2022. That longer-duration profile combined with bond-picking missteps, especially in investment-grade corporates, led to an 11.72% loss, 1.38 percentage points worse than the median.

Differences in exposures to leveraged loans and CMBS can lead to performance divergences between the strategy’s global vehicles in any given year, but over the long haul the results across the vehicles, adjusted for currency effects, should be close. For example, from the European vehicle’s late 2022 inception through August 2026, it has returned 7.44% in USD annually, gross of fees, versus 7.61% for the US mutual fund.

American Funds Multi-Sector Inc 529-F-3's Prospectus Adjusted Expense Ratio is 0.42% per year. It places it in the cheapest quintile of the Morningstar US Fund Multisector Bond Category, where the median fee is 0.76% per year. This cost positioning translates into a Medalist Rating Price Score of 2.11, which reflects its relative price positioning within the category. The Price Score ranges from -2.50 (most expensive) to +2.50 (cheapest), with higher scores indicating better cost competitiveness.
