BBAG vs IUSB

BBAGAJPMorgan BetaBuilders U.S. Aggregate Bond ETF

IUSBAiShares Core Universal USD Bond ETF

In short

BBAG Core US bond exposure for 0.03% a year. JPMorgan turned up late to the Agg price war in 2018 and came in at the floor, matching the fee charged by rivals many times its size.

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

BBAG The fund seeks results that closely track the Bloomberg U.S. Aggregate Bond Index, which represents the U.S. investment-grade fixed-rate bond market.

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

• BBAG 0.03% a year sits on the category's price floor, level with AGG, BND, SPAB and SCHZ and far below the typical core-bond fund.
• The whole job is hugging the Bloomberg U.S. Aggregate Bond Index, and it does that tightly: among the closer trackers in a crowded core-bond field.jpmorgan.com
• One line item covers roughly 1,700 investment-grade, fixed-rate US bonds. No issue picking, no maturity ladders to babysit.
• Distributions come monthly, not quarterly, so income lands on a steadier cadence.

• 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

• BBAG Interest rates drive this thing. Broad investment-grade bonds lose price when yields rise, and the fund carries that exposure undiluted.
• Investment grade, fixed rate, US only. High-yield credit, floating-rate paper and foreign bonds sit outside the mandate by design.
• Smaller and less heavily traded than AGG and BND, so spreads can run wider. Limit orders matter more here than with the giants.

• 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.
