AGG vs AGGA

AGGAiShares Core U.S. Aggregate Bond ETF

AGGACEA Astoria Dynamic Core US 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.

AGGA AGGA doesn't buy bonds. It buys bond ETFs, with an active manager at Astoria shifting the mix and aiming to beat the plain vanilla aggregate index. A 2025 launch charging 0.55% for that judgment.

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.

AGGA The Fund seeks current income. It is actively managed and invests primarily in other U.S. fixed income ETFs to provide core fixed-income exposure while seeking to outperform broad fixed-income benchmarks.

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.

• AGGA One ticker, an outsourced bond desk. The manager moves between US fixed income ETFs instead of tracking a fixed index sleeve, and the mandate reaches beyond the US into emerging market debt.
• Income is the stated job, not a byproduct. The prospectus objective is current income, and the fund pays on a monthly schedule.
• The portfolio matches the label: core US fixed income assembled from other bond ETFs, which is exactly what the filing describes, with no structural red flags on the record.

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.

• AGGA At 0.55%, you pay for the active call on top of whatever the underlying ETFs charge. Index core bond funds like BND, SCHZ and SPAB charge a small fraction of that.
• Launched in April 2025, so there is little history to judge the manager by, and it is not among the heavily traded names in its category. Limit orders matter.
• It sits in the lower half of a crowded core bond peer group, where cheap index giants set the bar.
