Our read on FUSI

ETF.net Research

BMost ultra-short bond funds park you in T-bills. FUSI goes hunting instead: an actively run basket of investment-grade floating-rate credit (CLOs, mortgages, corporate paper) whose coupons reset with short-term rates.

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

  1. 01The coupons float. Holdings are investment-grade floating-rate securities, so payments reset with short-term rates instead of locking into a fixed coupon.res.americancentury.com
  2. 02Multisector by design: CLOs, commercial and residential mortgages, corporate credit. Roughly 60 positions, with managers shifting between sectors rather than tracking a fixed list.
  3. 03The mandate is blunt about priorities: current income first, long-term capital appreciation second, measured against the Bloomberg U.S. 1-3 Month Treasury Bill Index.

Worth knowing

  1. 01It charges 0.27% a year against a 0.20% category median, and the cheap index anchors on this shelf (VUSB at 0.10%, SHV at 0.15%) set a low bar to clear.
  2. 02Floating coupons trim interest-rate risk, not credit risk. Structured credit is investment grade here, but it does not behave like a Treasury bill when markets get jumpy.
  3. 03One of the smaller, more thinly traded names in the ultra-short group, so bid-ask spreads can run wider than the cash-parking giants'.
