AGG vs NUAG

AGGAiShares Core U.S. Aggregate Bond ETF

NUAGANuveen Enhanced Yield U.S. Aggregate Bond

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.

NUAG The Agg, re-sorted for income. NUAG tracks an ICE BofA index that takes the same investment-grade universe and tilts weight toward its higher-yielding corners, with rules fencing in how far duration and credit quality can drift. Fee: 0.16%.

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.

NUAG The Fund seeks to track, before fees and expenses, the investment results of the ICE BofA Enhanced Yield U.S. Broad Bond Index.

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.

• NUAG Not a market-cap clone. The index buckets the investment-grade universe by asset class, sector, credit, duration and maturity, then leans into higher-yielding buckets while limiting drift from the base index.nuveen.com
• 0.16% sits below the typical fee in the core-bond aisle, which is unusual for a rules-based tilt rather than a plain market-cap tracker.
• Broad plumbing underneath: roughly 1,500 holdings spanning Treasuries, corporates, residential and commercial mortgage paper and asset-backed debt. Pays monthly.nuveen.com
• Running since 2016 and it owns this lane: no other fund in our core-bond coverage tracks the same enhanced-yield index. The portfolio has stayed tight to its stated mandate.

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.

• NUAG Small and thinly traded next to the category's giants, so spreads can be wider and size matters when you trade.
• Plain-vanilla Agg trackers (AGG, SPAB and SCHZ) charge 0.03%. The reweighting engine is what the extra cost buys.
• Tilting toward yield means tilting toward credit and spread risk. The rules cap how far sector weights, duration and tracking error can wander from the Agg, but they do not erase the difference.nuveen.com
