GVI vs SPAB

GVIAiShares Intermediate Government/Credit Bond ETF

SPABAState Street SPDR Portfolio Aggregate Bond ETF

In short

GVI Most core bond funds swallow the whole market, long end included. GVI keeps to the middle: US government and investment-grade corporate bonds maturing in one to ten years, nothing longer. Running since 2007, pays monthly.

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

GVI The fund seeks to track an index of U.S. government and investment-grade corporate bonds maturing from one to ten years. Its stated purpose is to help balance income and interest-rate risk.

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

• GVI The mandate is narrow on purpose: US government and investment-grade corporate bonds, one to ten years to maturity, built to balance income against interest-rate risk.ishares.com
• 0.20% a year, well under the typical fee in its core-bond peer group, from a fund that has been trading since 2007.
• It holds what its Bloomberg index holds, closely, which is why it rates as one of the stronger builds among the core bond funds we grade.
• Income lands monthly, and with billions in assets this is an established listing rather than a thin niche product.

• 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

• GVI Whole-market core rivals BND, SPAB and SCHZ run at 0.03%. The intermediate-only cut costs more than the everything-bond version.
• Capping maturities at ten years softens rate swings, it does not remove them, and the corporate sleeve carries credit risk Treasuries do not.ishares.com
• Trading is moderate rather than heavy, so spreads can widen on large or hurried orders.

• 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
