SPAB vs VCOB

SPABAState Street SPDR Portfolio Aggregate Bond ETF

VCOBBVoya Core 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.

VCOB An actively managed take on the core bond aisle: investment-grade corporates, government and mortgage debt, run by Voya's bond team at a price that undercuts the typical fund in the category.

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.

VCOB The Fund is an actively managed ETF seeking total return through current income and capital appreciation. It normally invests at least 80% of net assets in bonds or bond-like derivatives, primarily including investment-grade corporate, government, and mortgage-related debt.

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.

• VCOB Active mandate, not an index clone: normally at least 80% of net assets in bonds, spanning investment-grade corporate, government and mortgage-related debt.
• Charges 0.25%, below the typical fund in its core-bond cohort, which is uncommon for an actively run strategy.
• Pursues total return from two directions, current income plus capital appreciation, inside a standard 1940 Act ETF wrapper.

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

• VCOB Cheap for active, still dearer than the aisle's index heavyweights: BND, SPAB and SCHZ each charge 0.03%.
• Launched in late 2025, so there is little live record of how the managers navigate a full rate cycle.
• A small, lightly traded fund next to the category's household names, so bid-ask spreads are worth checking before trading.
