AGGYAWisdomTree Yield Enhanced U.S. Aggregate Bond Fund

SPABAState Street SPDR Portfolio Aggregate Bond ETF

In short

AGGY Same bond universe as the big Agg trackers, rearranged. AGGY re-weights the Bloomberg U.S. Aggregate Bond Index toward its higher-yielding slices under a rules-based approach, while aiming to preserve broadly familiar risk characteristics.

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

AGGY The fund seeks to enhance income by re-weighting components of the Bloomberg U.S. Aggregate Bond Index through a rules-based approach while broadly preserving familiar risk characteristics.

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

• AGGY The mandate is the differentiator: a rules-based re-weighting of the Agg rather than a copy of it, so you get index discipline with an income tilt built in.
• 0.12% a year sits well below the typical fee in the aggregate-bond category, unusual for a fund that does something other than replicate the benchmark.
• Roughly 2,500 bonds and monthly distributions: broad diversification with an income stream that arrives on a regular cadence.
• Trading since 2015 and one of the tighter implementations in a crowded aggregate-bond peer group, with a portfolio that closely matches the mandate it advertises.

• 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

• AGGY Reaching for yield inside the Agg means leaning harder into credit and rate sensitivity, so it screens as riskier than the average fund in its category.
• Plain trackers of the same index (AGG, BND, SPAB) charge 0.03%, so the re-weighting is what you are paying the extra fee for.
• Mid-sized and moderately traded rather than a category heavyweight, so bid-ask spreads can run wider than the largest Agg funds.

• 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
