AGG vs WABF

AGGAiShares Core U.S. Aggregate Bond ETF

WABFCWestern Asset Bond ETF

In short

AGG Launched in 2003, one of the first funds to pack the entire U.S. investment-grade bond market into a single ticker: Treasuries, corporates and mortgage bonds, three basis points a year, cash paid monthly.

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

AGG The fund seeks to track the Bloomberg U.S. Aggregate Bond Index, providing broad exposure to the total U.S. investment-grade bond market.

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

Why people hold it

• AGG 0.03% a year against a peer-group median near 0.36%. On a bond fund, the fee comes straight out of the coupon, so the gap matters more than it looks.
• A $100 billion-plus fund and very actively traded, the kind of depth that keeps bid-ask costs down for retail-sized orders.
• Tracks the Bloomberg U.S. Aggregate closely, with one of the tightest index-following records in its peer group. Income is distributed monthly.
• Running since 2003, giving it one of the longest track records among U.S. bond index ETFs.

• 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

• AGG Investment grade and U.S. dollar only. High-yield debt and foreign bonds sit outside the mandate, so this is designed as core ballast rather than a yield hunt.
• Rate risk comes as it comes. The index gets tracked whether yields rise or fall, with no manager stepping in to shorten duration.
• The same index is sold by SPAB, SCHZ and BBAG at the same 0.03%. The portfolio is the commodity here; scale and trading depth are the tiebreakers.

• 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
