IUSBAiShares Core Universal USD Bond ETF

In short

CRDT Not an index bond fund. CRDT roams high yield, investment grade and distressed debt hunting income, run by an alternatives shop that also handles the hedging, and it pays monthly.

IUSB Most core bond funds stop at investment grade. IUSB keeps going, folding high-yield USD debt into the same wrapper across roughly 18,000 bonds, for 0.06% a year.

Stated mandate

CRDT CRDT seeks current income as its primary objective, with long-term capital appreciation as a secondary objective.

IUSB The Fund seeks to track an index of U.S.-dollar-denominated bonds spanning investment-grade and high-yield sectors.

Why people hold it

  • CRDT Active across the credit spectrum: investment grade and high yield corporate bonds, preferred stock, Treasuries and bank loans, chosen by bottom-up research instead of an index.simplify.us
  • Sub-advised by Asterozoa Capital, an alternatives manager responsible for both fixed income security selection and the fund's derivatives strategy.simplify.ussimplify.us 2
  • The prospectus puts guardrails on the racy stuff: up to 15% in illiquid holdings such as distressed or private investments, and no more than 10% rated CCC or lower.simplify.us
  • Pays monthly, with current income as the stated primary objective and long-term capital appreciation second.
  • IUSB 0.06% a year, a fraction of what the typical broad bond fund in its category charges, and iShares has run it since 2014.
  • Roughly 18,000 bonds spanning investment-grade and high-yield sectors, so one ticker covers ground a plain Agg tracker leaves on the table.ishares.com
  • Tracks its index closely, trades heavily, and sits on a multi-billion-dollar asset base. Income is paid monthly.
  • Among the strongest implementations in a crowded field of nearly 200 core bond funds.

Worth knowing

  • CRDT The 0.99% expense ratio is alternatives-manager pricing next to index core bond funds like BND at 0.03%. Active credit selection has to cover that gap.
  • Small and thinly traded, so bid-ask spreads can run wider than the giant core bond ETFs. Limit orders matter more here.
  • Junk and distressed debt move more like stocks than Treasuries when credit sours, and the fund currently sits in the bottom quartile of our aggregate-bond group.simplify.us
  • IUSB That high-yield sleeve is the trade-off: more credit risk than an investment-grade-only fund, and more movement when spreads widen.
  • BND, SPAB and SCHZ charge 0.03%, half IUSB's fee, but they stay inside investment grade.
  • Payouts land monthly, but the amount floats with the coupons underneath. Nothing about the income stream is fixed.
