Our read on SPAB
AA 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.
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
- 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
- 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
