BDBTBBluemonte Core Bond ETF

BKAGABNY Mellon Core Bond ETF

In short

BDBT An active manager's take on the plainest job in bonds: core fixed income at 0.22% net of a waiver through August 31, 2027, below the typical core bond fund, paid out monthly.

BKAG A core bond index fund that charges nothing. BKAG tracks the same Bloomberg US Aggregate benchmark the giants track, at a 0.00% expense ratio, and has been doing it since 2020.

Stated mandate

BDBT The Fund seeks total return and income. It is actively managed and normally invests at least 80% of net assets, including investment borrowings, in investments providing exposure to bonds.

BKAG The fund seeks to track the Bloomberg US Aggregate Total Return Index.

Why people hold it

• BDBT Active management priced like a cheap fund: 0.22% net of a waiver through August 31, 2027 (0.27% gross), below the category median across 114 funds.
• Distributions land monthly, not in quarterly lumps.
• Does what the prospectus says: total return and income, with at least 80% of net assets in bond exposure, and a portfolio that lines up closely with that mandate.sec.gov
• Lands in the upper half of a crowded broad bond field whose leaders are nearly all index trackers.

• BKAG A 0.00% expense ratio. The median fund in the core bond group charges 0.36%, and even the cheap giants (BND, SPAB, SCHZ) charge 0.03%.
• Tracks the Bloomberg US Aggregate Total Return Index tightly, one of the closest index-following records in its peer group.
• Broad by design: roughly 4,000 bonds in the portfolio, with distributions paid monthly rather than quarterly.
• A multi-billion-dollar fund from BNY Mellon, wrapped in a standard 1940 Act ETF structure with no exotic mechanics.

Worth knowing

• BDBT The index giants are far cheaper: AGG, BND, SPAB and SCHZ each charge 0.03%. You are paying up for the active call.
• The 0.22% depends on a waiver running through August 31, 2027. The stated gross fee is 0.27%.
• Launched June 2025, so the record is short and spans one rate backdrop. Trading is moderate rather than heavy, so limit orders earn their keep.

• BKAG Rate risk is the trade-off. This is full-market bond exposure, and bond prices move opposite interest rates. Volatility is the weakest part of its profile.
• Moderately traded, not one of the volume monsters in the category. Spreads and limit orders matter more here than with the largest core bond names.
• At zero, the fee edge over 0.03% rivals is real but small in dollar terms, so tracking and trading costs do more of the work.
