American Century Multisector Income ETF (MUSI)

The American Century Multisector Income ETF (MUSI) is an exchange-traded fund that invests in a broad range of dividend-paying companies across different sectors of the economy. It aims to deliver a combination of current income and the potential for long-term capital growth, making it suitable for investors seeking regular cash distributions rather than pure price appreciation.

What MUSI holds and why

MUSI constructs a portfolio around dividend-yielding equities — typically stocks from large and mid-sized companies that have a history of paying dividends. Rather than focusing on a single sector like utilities or energy, MUSI spreads its holdings across finance, consumer goods, healthcare, industrials, real estate, telecommunications, and other areas. This multisector approach is the fund’s defining feature: it seeks to capture income opportunities wherever they appear in the economy rather than betting on any one industry to perform.

The fund targets companies that American Century Investments’ managers believe can sustain and possibly grow their dividend payments over time. This differs from a pure yield chase, where a fund might simply buy whatever stocks pay the highest immediate payout. Instead, MUSI screens for financial strength and a demonstrated capacity to maintain distributions through economic cycles — the kind of company that keeps paying dividend even when earnings dip.

Income, diversification, and the expense ratio

MUSI’s primary appeal is its yield. Because it focuses on dividend-paying stocks, the fund typically distributes income quarterly or monthly (exact frequency depends on the composition at any given time). That cash flow is attractive to retirees, people living on portfolio income, and anyone seeking to reduce reliance on volatile capital appreciation to meet spending needs.

The diversification across sectors and companies acts as a dampener on volatility. A downturn in one industry — say, a rate hike that crushes bank stocks — is partially offset by strength elsewhere. An investor holding just telecom or utility stocks bears the full brunt of sector moves; MUSI holders spread that risk thinner.

The fund charges a low expense ratio, typical of passive or semi-passive equity ETFs, meaning that a high percentage of dividends actually reach the investor’s pocket rather than flowing to the fund manager.

How MUSI sits in the income-investing landscape

MUSI occupies a middle ground in the income-ETF space. It is far broader than a sector-specific fund like a utilities ETF, which might yield higher but concentrates bets on one part of the market. It is also different from a U.S. Treasury or investment-grade bond ETF, which offer more predictable returns and lower volatility but typically yield less. For someone unwilling to accept bond duration risk but seeking meaningful income from equities, MUSI provides a more balanced entry point.

The fund is also less aggressive than a high-yield-bond ETF or a mortgage-real-estate investment trust ETF — both of which chase higher yields but accept credit risk or structure complexity that MUSI sidesteps by sticking to common equities.

What can go wrong

The primary risk is that the equities MUSI holds decline in value. A broad stock market recession will pull down the fund’s net asset value alongside most others. Because MUSI tilts toward mature, profitable companies that pay dividends, it is less vulnerable to downturns than a fund of growth stocks, but it is not immune.

A second risk is that companies cut their dividends. If a technology giant that makes up a meaningful portion of MUSI’s holdings faces earnings pressure and slashes its payout, the fund’s yield falls. This risk is partly mitigated by MUSI’s focus on stable, financially strong firms, but it never disappears entirely.

Interest-rate moves are a subtler pressure. When bonds become more attractive (typically when the Federal Reserve raises rates), dividend-paying stocks can lose relative appeal, as income investors reconsider whether a 3% dividend yield on a stock is worth the volatility when a Treasury bond now pays nearly as much with no price risk. This can depress valuations of dividend stocks even if the businesses themselves are healthy.

Finally, MUSI is subject to concentration risk — if a small number of large stocks make up a large share of assets, the fund’s performance becomes hostage to those names. American Century works to manage this through diversification, but concentration remains a structural feature of any portfolio of the most dividend-friendly stocks.

How to research MUSI

Start by checking the fund’s fact sheet on the American Century Investments website, which lists the current holdings, the fund’s yield, its rolling performance, and sector breakdowns. The prospectus and annual report provide deeper detail on the fund’s investment process and strategy. Because MUSI holds common stocks, its holdings change frequently, so reviewing the fact sheet quarterly helps you understand where your money is deployed.

Compare MUSI’s yield, expense ratio, and performance track record to peer income ETFs such as the Schwab U.S. Dividend Equity ETF and other multisector income funds. A fund’s distribution rate and consistency of that rate over time matter more than a single period’s yield, which can be distorted by market swings.

The fund’s turnover ratio (how often the manager trades holdings) also deserves attention. Higher turnover can obscure true portfolio costs and suggests the manager is making more tactical shifts, while lower turnover suggests a more stable, buy-and-hold approach.
