Our read on MBSD
BAgency mortgage bonds let their duration wander as homeowners refinance or sit tight. MBSD tracks an index built to keep that drift on a leash, offering mortgage-bond exposure with rate sensitivity set by rules instead of by the market's mood.
The fund is designed to provide market-like exposure to mortgage-backed securities while limiting duration drift through a rules-based index methodology.
Why people hold it
- The whole point is duration discipline: a rules-based index designed to give market-like mortgage-bond exposure while limiting duration drift, so rate sensitivity is governed by methodology.flexshares.com
- Charges 0.21% a year, less than the typical fee in the MBS ETF group, and it has been running since 2014 rather than arriving as a recent idea.
- Spreads across roughly 500 mortgage bonds and pays monthly, so income lands on a mortgage-payment rhythm instead of twice a year.
Worth knowing
- Thinly traded. Spreads and limit orders matter more here than with the category's household names.
- Duration control carries a price tag: VMBS, MBB and SPMB track the broad agency mortgage market for single-digit basis points.
- Constraining duration means it is not built to move like the full mortgage-backed market. That is the design, but it is a different exposure, not a copy.flexshares.com
