AGGMAiShares 1-10 Year U.S. Aggregate Bond ETF

IUSBAiShares Core Universal USD Bond ETF

In short

AGGM Government and credit, nothing else: GBF holds Treasuries and investment-grade corporate bonds across the maturity spectrum, tracking a Bloomberg index since 2007 for 0.20% a year.

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

AGGM The fund seeks to track an index of U.S. dollar-denominated government and investment-grade corporate bonds, providing diversified fixed-income exposure across sectors and maturities.

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

AGGM A 0.20% fee, below the typical core bond ETF in its category.
Tracks the Bloomberg U.S. Government/Credit Bond Index tightly, one of the cleanest index implementations in a crowded core-bond field.
Pays monthly, so income arrives on a steady cadence rather than quarterly.
Live since 2007 under the iShares roof, with a full market cycle of history behind the mandate.

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

AGGM It trades lightly next to the category's giants. Limit orders matter more here than with the household-name bond funds.
Broad total-bond rivals undercut it on fee: BND, SPAB and SCHZ each run 0.03%, though their indexes also include securitized debt.
Rate risk is the main lever. The index spans sectors and maturities, so prices move inversely to yields, and longer bonds move most.

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.
