NUAGANuveen Enhanced Yield U.S. Aggregate Bond

SPABAState Street SPDR Portfolio Aggregate Bond ETF

In short

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%.

SPAB A 2007-vintage core bond fund priced at 0.03%: roughly 8,500 US investment-grade bonds in one ticket, at the same rock-bottom fee the household names charge for the same index.

Stated mandate

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

SPAB The fund seeks to track the price and yield performance of the Bloomberg U.S. Aggregate Bond Index before fees and expenses, providing broad exposure to U.S.-dollar-denominated investment-grade bonds.

Why people hold it

• 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.

• SPAB 0.03% a year against a 0.36% median for its peer group, and the same ticket price as AGG, SCHZ and BBAG on the identical index.
• Roughly 8,500 dollar-denominated investment-grade bonds in one line item, tracking the Bloomberg U.S. Aggregate Bond Index. Diversification you could not assemble bond by bond.ssga.com
• Trades actively and has tracked its index closely, putting it among the stronger implementations in the core-bond group.
• Running since 2007, now a multi-billion-dollar fund, and it pays monthly rather than quarterly.

Worth knowing

• 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

• SPAB Bond prices move opposite yields. When rates rise the index falls and the fund follows it down; a 0.03% fee cannot cushion that.
• AGG, SCHZ and BBAG hold the same declared index at the same 0.03%. Picking among them comes down to spreads and platform, not the portfolio.
• Investment grade and US dollar only by mandate: high yield and foreign-currency debt sit outside the remit.ssga.com
