AGG vs JIII

AGGAiShares Core U.S. Aggregate Bond ETF

JIIICJanus Henderson Income ETF

In short

AGG Launched in 2003, one of the first funds to pack the entire U.S. investment-grade bond market into a single ticker: Treasuries, corporates and mortgage bonds, three basis points a year, cash paid monthly.

JIII Active multi-sector income from Janus Henderson, built to sit between a core bond fund and a single-sector high-yield fund. Pays monthly. Costs 0.54%, net of a waiver through February 28, 2028.

Stated mandate

AGG The fund seeks to track the Bloomberg U.S. Aggregate Bond Index, providing broad exposure to the total U.S. investment-grade bond market.

JIII The fund seeks long-term returns through a combination of income and capital growth.

Why people hold it

• AGG 0.03% a year against a peer-group median near 0.36%. On a bond fund, the fee comes straight out of the coupon, so the gap matters more than it looks.
• A $100 billion-plus fund and very actively traded, the kind of depth that keeps bid-ask costs down for retail-sized orders.
• Tracks the Bloomberg U.S. Aggregate closely, with one of the tightest index-following records in its peer group. Income is distributed monthly.
• Running since 2003, giving it one of the longest track records among U.S. bond index ETFs.

• JIII Actively managed across bond sectors, US and non-US, instead of tracking one index. Janus Henderson positions it between a core bond fund and a constrained high-yield fund.janushenderson.com
• Income comes first in the mandate, capital appreciation second, and cash goes out monthly rather than quarterly.janushenderson.com
• Roughly 500 holdings spread across credit, securitized and government debt, so the risk is not purely a bet on Treasury rates.janushenderson.com

Worth knowing

• AGG Investment grade and U.S. dollar only. High-yield debt and foreign bonds sit outside the mandate, so this is designed as core ballast rather than a yield hunt.
• Rate risk comes as it comes. The index gets tracked whether yields rise or fall, with no manager stepping in to shorten duration.
• The same index is sold by SPAB, SCHZ and BBAG at the same 0.03%. The portfolio is the commodity here; scale and trading depth are the tiebreakers.

• JIII At 0.54% net of a waiver through February 28, 2028 (0.56% gross), it sits above the category median, while index trackers AGG, BND and SPAB each charge 0.03%.
• Launched in 2024, so the live record is short, and the fund trades moderately rather than heavily.
• A manager's sector calls drive the portfolio, which can leave it looking quite different from a plain aggregate-bond index fund.janushenderson.com
