Our read on JMBS

ETF.net Research

AThe 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.

Stated mandate

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

Why people hold it

  1. 01Charges 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.
  2. 02First 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
  3. 03A 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.
  4. 04Does what its documents say it does, and stands as one of the stronger implementations in its broad-bond peer group.

Worth knowing

  1. 01This 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%.
  2. 02Mortgage 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
  3. 03The 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.
