Our read on FUSI

ETF.net Research

In short

BMost funds in this corner of the bond market own one thing: AAA CLO tranches. FUSI casts wider, running an actively managed, ultrashort book across CLOs, commercial and residential mortgages and corporate credit, at 0.19% a year.

Stated mandate

The fund seeks current income and, secondarily, long-term capital appreciation. It invests primarily in investment-grade floating-rate securities across CLOs, commercial and residential mortgages, corporate credit, and similar structured investments, with tactical sector allocation.

Why people hold it

  • The multisector angle. Rather than AAA CLOs alone, the managers range across CLOs, commercial and residential mortgages and corporate credit, primarily investment grade, with duration kept under a year.americancentury.com
  • 0.19% a year, with no waiver propping it up, below the category median and level with PAAA. Fidelity's FAAA and FCLO sit at 0.00% net, but only under waivers running through January 31, 2027.
  • Pays monthly, and the stated benchmark is the Bloomberg U.S. 1-3 Month Treasury Bill Index. The yardstick here is cash, not the broad bond market.

Worth knowing

  • The mandate shifted. Effective September 14, 2026 the fund was renamed from Multisector Floating Income to Ultrashort Income and dropped its policy of keeping at least 80% in floating-rate securities.sec.gov
  • One of the smaller, lighter-traded names in a category stacked with multi-billion-dollar CLO funds, so spreads can run wider than the headline names and limit orders are the usual tool.
  • Fully active with no index to replicate: the sector mix, credit calls and holdings (roughly 110 positions) come from the management team, not a published rulebook.
