FUSI ETF: What Is It? A Complete Guide to Returns, Expense Ratio, Holdings, and Alternative ETFs
The American Century Multisector Floating Income ETF, or FUSI ETF, is an actively managed fund that diversifies across floating-rate-style bond sectors. It is an income ETF for which investors should weigh the interest rate environment, credit risk, distribution history, management fee, and dividend outlook together.
SubscribeWhat Is the American Century Multisector Floating Income ETF?
The FUSI ETF is an actively managed ETF that seeks income by accessing several income-oriented asset classes, including floating-rate-style bonds and structured bonds. It uses the Bloomberg U.S. short-term Treasury index as a performance benchmark, but it does not replicate that index.
It is suited to investors who want income assets with lower sensitivity to interest rate changes and who can accept credit and liquidity risk.
The fund is an actively managed ETF run by American Century.

American Century selects and holds bonds from several sectors, including floating-rate-style bonds, secured bonds, and bonds tied to residential and commercial real estate. The management team adjusts the portfolio mix based on interest rate levels, credit conditions, and liquidity, and it does not mechanically follow the weights of a specific index.
- Access to floating-rate-style income assets
- Active management that draws on several bond sectors
American Century Multisector Floating Income ETF Size and Costs (AUM and Management Fees)
Assets under management (AUM) stand at $73.2M, and the total expense ratio is 0.19% per year.
Because management judgment has a larger influence on an active bond ETF than on an index-tracking product, it is important to compare not only fees but also the credit risk of the underlying holdings and trading conditions.
American Century Multisector Floating Income ETF Performance and Trends
1-Year Price Performance
Dividend & Yield
52-Week Price RangeThe price and distribution sources of the FUSI ETF can be affected by interest rate expectations and changes in credit conditions in the structured bond market. Floating-rate assets may aim to reduce sensitivity to interest rate moves, but volatility tied to credit risk and liquidity conditions remains.
Fund flows can be influenced by the relative appeal of cash-like assets and short-term bonds, market expectations for the direction of interest rates, and changes in credit spreads. In particular, for a micro-cap ETF, it is necessary to check trading volume and bid-ask conditions and to monitor the gap between the market price and net asset value.

American Century Multisector Floating Income ETF Investor Checkpoints
Before adding the FUSI ETF to a portfolio, investors should review the role of floating-rate assets, structured bond exposure, distribution history, and trading conditions together. Even an income-seeking strategy carries the possibility of principal loss, and the ease of trading a micro-cap ETF should also be checked.
| Checkpoint | What to Check | Current Status |
|---|---|---|
| Fee burden | How fees and trading costs affect long-term holding returns | Needs confirmation |
| Distribution history | Review past payments and the irregularity of the schedule | Has a distribution history, irregular schedule |
| Credit exposure | Review the composition of underlying assets and credit risk | Structured bond exposure |
| Currency impact | How exchange rates affect performance in Korean won terms | Confirm whether currency hedging applies |
A floating rate alone does not eliminate the risk of loss. The repayment capacity of underlying assets, market liquidity, the valuation methods for structured bonds, and changes in interest rates and credit spreads can all act at the same time. During periods of market volatility, the gap between the trading price and net asset value can also widen.
The FUSI ETF can be a candidate for investors who consider the short-term interest rate environment and their income needs together. However, because its management discretion and holdings differ from those of index-tracking bond ETFs, it is appropriate to first check the distribution history, costs, and credit and liquidity risks.
