SPAB vs VPLS

SPABAState Street SPDR Portfolio Aggregate Bond ETF

VPLSAVanguard Core-Plus Bond ETF

In short

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.

VPLS Vanguard's active bond desk in an ETF wrapper. The "plus" is permission to roam past U.S. investment grade into high yield and emerging market debt, benchmarked to the broader Universal index instead of the plain Agg, for 0.20% a year.

Stated mandate

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.

VPLS The fund seeks total return and moderate to high current income. It invests mainly in investment-grade U.S. bonds, with selective below-investment-grade and foreign debt exposure, including emerging markets, and is actively managed.

Why people hold it

• 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.

• VPLS 0.20% a year for an actively run bond book, comfortably under the 0.36% median for broad bond ETFs. Vanguard's fixed income team, at index-adjacent money.vanguard.com
• The "plus" is the point: Treasuries, agency mortgages and investment-grade credit at the core, plus room for high yield and emerging market debt the plain Agg skips.vanguard.com
• Well over a thousand bonds, so no single issuer moves the needle much, and cash goes out monthly rather than quarterly.
• Does what its prospectus says it does, and sits in the top quartile of the broad bond group.

Worth knowing

• 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

• VPLS Index Aggs like BND, SPAB and SCHZ charge 0.03%. The gap buys a human team's judgment, which can land behind the benchmark as easily as ahead.
• The high yield and emerging market sleeve carries credit risk a pure investment-grade fund does not, and those are the bonds that wobble when investors turn defensive.vanguard.com
• Moderately traded rather than a giant of the bond aisle, and it launched in 2023, so there is less history behind it than the long-running index Aggs.
