SPABAState Street SPDR Portfolio Aggregate Bond ETF

In short

BBAG Core US bond exposure for 0.03% a year. JPMorgan turned up late to the Agg price war in 2018 and came in at the floor, matching the fee charged by rivals many times its size.

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

BBAG The fund seeks results that closely track the Bloomberg U.S. Aggregate Bond Index, which represents the U.S. investment-grade fixed-rate bond market.

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

• BBAG 0.03% a year sits on the category's price floor, level with AGG, BND, SPAB and SCHZ and far below the typical core-bond fund.
• The whole job is hugging the Bloomberg U.S. Aggregate Bond Index, and it does that tightly: among the closer trackers in a crowded core-bond field.jpmorgan.com
• One line item covers roughly 1,700 investment-grade, fixed-rate US bonds. No issue picking, no maturity ladders to babysit.
• Distributions come monthly, not quarterly, so income lands on a steadier cadence.

• 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

• BBAG Interest rates drive this thing. Broad investment-grade bonds lose price when yields rise, and the fund carries that exposure undiluted.
• Investment grade, fixed rate, US only. High-yield credit, floating-rate paper and foreign bonds sit outside the mandate by design.
• Smaller and less heavily traded than AGG and BND, so spreads can run wider. Limit orders matter more here than with the giants.

• 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
