SPAB vs WABF

SPABAState Street SPDR Portfolio Aggregate Bond ETF

WABFCWestern Asset 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.

WABF Western Asset has run bond money since 1971, and WABF is that core-plus playbook in ETF form: an actively picked book of roughly 400 US bonds, paid out monthly, with room to reach into high yield.

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.

WABF The Fund seeks to maximize total return while maintaining prudent investment management and meeting liquidity needs.

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.

• WABF Active, but with a leash: managers aim to keep average effective duration within 20% of the domestic bond market's, so security selection does the work rather than big rate bets.franklintempleton.com
• Up to 20% can sit in below-investment-grade bonds, and the fund intends to stay in US dollar securities, so the yield lever comes without currency exposure.businesswire.com
• A 0.35% expense ratio lands right at the aggregate-bond category median, unusual for a fund where a human team is making the calls.
• Income arrives monthly, and the portfolio hews closely to the broad US total-return mandate its prospectus describes.

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

• WABF Index rivals BND, SPAB and SCHZ charge 0.03%. Active management here costs about ten times the cheapest route to core US bonds, a gap the manager has to earn back.
• Small asset base and light trading volume. Spreads can be wider than on the giant index funds, and limit orders are the norm in this corner of the market.
• That high-yield sleeve cuts both ways: credit stress can bite harder here than in a pure investment-grade index tracker.businesswire.com
