IUSB vs ZHOG

IUSBAiShares Core Universal USD Bond ETF

ZHOGCF/m Opportunistic Income 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.

ZHOG A go-anywhere active bond fund in a category ruled by index trackers. F/m's team roams U.S. fixed income for relative value, keeps duration short and average credit quality investment grade, and pays monthly. Fee: 0.43%, no waiver.

Stated mandate

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

ZHOG The Fund seeks attractive income by identifying undervalued and opportunistic sectors and securities in U.S. fixed-income markets, while generally limiting duration and maintaining average investment-grade credit quality.

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.

• ZHOG Active and unconstrained: the mandate hunts undervalued sectors and securities across U.S. fixed income while generally limiting duration and keeping average credit quality investment grade.fminvest.com
• A focused book of roughly 60 positions, so the holdings list is short enough to actually read and see where the managers are leaning.
• Income is paid out monthly.
• Since January 1, 2026 it measures itself against the Bloomberg Short-Term U.S. Aggregate Index, a short-duration yardstick, while staying actively managed rather than tracking it.fminvest.com

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.

• ZHOG At 0.43% (gross and net, no fee waiver) it sits above the category median, and well above index anchors like AGG, BND and SCHZ at 0.03%.
• A small fund that trades lightly, so spreads and order size matter more here than with the category's giants.
• Outcomes ride on the team's calls, and that team was reshuffled effective January 1, 2026. The fund itself only launched in 2023.fminvest.com
