IUSBAiShares Core Universal USD Bond ETF

LSTBDNatixis ETF Trust Natixis Loomis Sayles Total Return Bond ETF

In short

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.

LSTB No data

Stated mandate

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

LSTB No data

Why people hold it

  • 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.

LSTB No data

Worth knowing

  • 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.
