AGG vs CPLS

AGGAiShares Core U.S. Aggregate Bond ETF

CPLSBAB Core Plus 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.

CPLS An actively run core-plus bond fund priced at 0.30%, with room to roam past the Agg into lower-rated and securitized credit. Built by a fixed-income house rather than an index shop, and launched in December 2023.

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.

CPLS The fund seeks to maximize total return through current income and long-term capital appreciation. It is actively managed and invests primarily in fixed-income securities, with selective exposure to lower-rated and securitized debt.

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.

• CPLS 0.30% sits below the median fee in its bond peer group and undercuts active core-plus rivals like FBND (0.36%), FLXR (0.40%) and DBND (0.45%).
• The Bloomberg U.S. Aggregate is the yardstick, not the cage: managers can add lower-rated and securitized debt that a pure index tracker has to skip.
• The portfolio matches its stated core-plus mandate closely, spreading risk across roughly 800 bonds and paying income monthly.
• Security selection is systematic and bottom-up, leaning on value and momentum signals rather than a single manager's macro hunch.alliancebernstein.com

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.

• CPLS Thinly traded and still a small fund, so spreads run wider than the giant Agg trackers. Limit orders earn their keep here.
• Plain index Agg funds (BND, AGG, SPAB) charge 0.03%. You are paying roughly ten times that for manager judgment, and that judgment is the whole difference.
• Launched in December 2023, so there is no track record spanning a full rate cycle. The 'plus' sleeve also adds credit risk the Agg does not carry.
