JMBS vs TRBF

JMBSAJanus Henderson Mortgage-Backed Securities ETF

TRBFBAngel Oak Total Return ETF

In short

JMBS The original actively managed mortgage-backed securities ETF, launched in 2018. Rather than replicate the MBS index, the team picks through agency mortgage bonds, a corner of the market where prepayment behavior makes security selection its own craft.

TRBF Angel Oak built its name in mortgage credit, and TRBF is that playbook in an ETF: an actively managed bond fund that hunts relative value across securitized and corporate paper instead of tracking the Agg.

Stated mandate

JMBS The fund seeks a high level of total return through both income and capital appreciation.

TRBF The Fund seeks total return. It is actively managed and allocates among fixed-income asset classes according to the Adviser’s assessment of relative value rather than tracking a specified index.

Why people hold it

• JMBS Charges 0.21% a year against a 0.36% median for its bond peer group, and that buys an active specialist mandate rather than an index tracker.
• First mover: Janus Henderson launched it in 2018 as the first actively managed MBS ETF in the US, and it now runs several hundred mortgage bonds.prnewswire.com
• A multi-billion-dollar fund that trades actively and pays monthly, which is a real edge in a corner of the bond market where most products stay small.
• Does what its documents say it does, and stands as one of the stronger implementations in its broad-bond peer group.

• TRBF No index to hug. The managers allocate across fixed-income asset classes on their own read of relative value, and the portfolio has tracked that stated mandate closely.
• Leans on the house specialty: corporate bonds plus non-agency RMBS, asset-backed and agency RMBS, with duration managed against the Bloomberg U.S. Aggregate, not pinned to it.angeloakcapital.com
• Income lands monthly, not quarterly, inside a plain 1940 Act ETF wrapper with no derivatives overlay or leverage sleeve driving the mandate.

Worth knowing

• JMBS This is one slice of the bond market, not a whole-market core. Broad aggregate funds such as BND, SPAB and SCHZ cover the full index for 0.03%.
• Mortgage bonds prepay. Homeowners refinance when rates fall and sit tight when they rise, so the portfolio's cash flows and rate sensitivity shift with the cycle.janushenderson.com
• The mandate targets total return from income plus price moves, so the monthly payout is not a fixed rate and the manager's calls drive the result.

• TRBF Above the category median on fee: 0.44% net of a waiver through September 30, 2027, against a 0.59% gross fee, versus 0.21% at JMBS.
• Launched in 2025, so the record is short and the fund is still a small, thinly traded one in its group. Spreads and premiums can matter more here than in the category's giants.
• Credit, not just rates. Non-agency mortgage and asset-backed holdings carry default and liquidity risk Treasury-heavy index funds avoid; results hinge on the adviser's calls.angeloakcapital.com
