AGG vs AVIG

AGGAiShares Core U.S. Aggregate Bond ETF

AVIGAAvantis Core Fixed 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.

AVIG A core US bond fund with a different brief: its stated goal is maximizing total return, not just mirroring the Bloomberg U.S. Aggregate. It costs 0.15% a year and spreads the risk across roughly 900 bonds.

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.

AVIG Seeks to maximize total return.

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.

• AVIG Charges 0.15% a year, well under half the median fee in its core bond cohort. Cost stops being the argument.
• Roughly 900 bonds, benchmarked to the Bloomberg U.S. Aggregate. The portfolio it actually runs lines up closely with the mandate in its own documents.avantisinvestors.com
• Among Agg-benchmarked funds, one of the stronger implementations in a crowded peer group, on both cost and portfolio construction.
• Launched in 2020 by Avantis as a broad US investment-grade bond holding, not a narrow slice of the market.avantisinvestors.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.

• AVIG Straight Agg index trackers (BND, AGG, SPAB) charge 0.03%. The extra basis points here buy a total-return mandate rather than a pure index copy.
• It's a core bond portfolio, so the price moves with interest rates. Rate sensitivity is the main risk you're carrying.
• Smaller and less heavily traded than the mega Agg trackers, so bid-ask spreads can run a touch wider.
