How it works
JMBS is actively managed, so it does not copy an index. It puts at least 80% of net assets into mortgage-related bonds, mainly mortgage-backed securities (MBS) issued by Ginnie Mae, Fannie Mae and Freddie Mac. MBS are bonds paid from pools of home loans. Up to 20% can go into mortgage bonds without a government agency behind them (non-agency) and other asset-backed bonds. Most holdings are investment grade, but some can be lower-rated "junk" bonds. The managers pick bonds one at a time. Over time, they aim to beat the Bloomberg US MBS Index by 0.50% after fees while tracking it closely. Portfolio turnover was 102%, a sign of frequent trading.
Much of the buying happens through "to be announced" (TBA) trades. These are agreements to buy pools of home loans that will be delivered on a future date. As of July 31, 2026, the largest positions were 30-year Fannie Mae/Freddie Mac pools (about 17% of net assets) and Ginnie Mae II 30-year pools (about 9%). Bond positions added up to about 162% of net assets. That reflects the leveraging effect of TBAs that the prospectus describes. The fund may also borrow through reverse repurchase agreements.
Small Treasury futures positions help the managers adjust duration, which measures how much bond prices react to interest-rate changes.
What it really costs
- JMBS charges 0.21% a year, versus an average of 0.28% for the similar funds below (4th of 8, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $22 in the first year and $268 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| JMBS | $22 | $68 | $118 | $268 |
Structure and tax notes
- Bond prices move opposite to interest rates; the longer the maturities it holds, the more its price reacts to rate changes.
In a retirement portfolio
It pays monthly from a portfolio of mostly government-backed mortgage bonds, with a trailing yield of 5.42% as of October 27, 2026.
JMBS paid $2.35 per share over the 12 months to October 27, 2026, a 5.42% yield, in monthly distributions. Rising interest rates hurt it badly. It lost 11.5% in 2022, its worst calendar year. Its deepest fall was 16.7%, from August 2021 to October 2022, and it took about 34.5 months to get back to its old high in September 2025. It held up better in the 2020 COVID crash, slipping 4.3% and recovering in about six weeks. The fund launched in 2018, so it has no 2008 record. Anyone who had to draw money in 2022 would have been cashing out shares at lower prices for almost three years.
It costs 0.21% a year, or $22 on $10,000 in the first year under the SEC's standard example. Past results don't predict the future. A plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Investors who want mostly government-backed mortgage bonds plus active managers aiming to beat the Bloomberg US MBS Index, and who accept a 0.21% fee for that.
- Income-focused holders who value monthly payments; the trailing yield was 5.42% as of October 27, 2026.
- Those comfortable with TBA trades, Treasury futures and up to 20% non-agency bonds, used to try to earn extra return.
Look elsewhere if
- Cost-focused investors: VMBS (0.03%) and MBB (0.04%) charge far less than JMBS's 0.21% for mortgage-bond exposure.
- Anyone who can't wait out long slumps: JMBS took about 34 months to recover from its 16.7% fall that ended in October 2022.
- Those wanting short-maturity or simple bond exposure: average maturity was 28 years, and bond positions totaled about 162% of net assets.

Questions investors ask
Does JMBS pay monthly dividends?
Yes. JMBS pays distributions monthly. Over the 12 months to October 27, 2026, it paid $2.35 per share, a trailing yield of 5.42%. The payments come mostly from interest on the home-loan bonds it holds. The amount can change from month to month as interest rates, mortgage prepayments and the fund's holdings change. A trailing yield shows what the fund paid in the past, not what it will pay.
What's the difference between JMBS and SPMB?
The biggest difference is cost. SPMB, the SPDR Portfolio Mortgage Backed Bond ETF, charges 0.04% a year. JMBS charges 0.21%, and its managers pick bonds and aim to beat the Bloomberg US MBS Index. As of October 27, 2026, JMBS returned 6.2% a year over three years, compared with 6.0% for SPMB. Over one year, JMBS lost 1.0% and SPMB lost 0.7%. The two funds are similar in size, with about $7 billion each in net assets.
Has JMBS beaten its benchmark?
So far, yes. As of December 31, 2025, JMBS returned 2.38% a year since its 2018 launch. The Bloomberg U.S. Mortgage Backed Securities Index returned 1.73% a year over the same period. Over five years, the fund returned 0.57% a year and the index 0.15%. Over one year, the fund returned 8.67% and the index 8.58%. The managers target 0.50% a year above the index after fees, and the prospectus says there's no assurance they will reach it.
Is JMBS safe for conservative investors?
It holds mostly government-backed bonds, but it can still lose money. As of July 31, 2026, about 89% of net assets were in bonds from government-sponsored enterprises such as Fannie Mae and Freddie Mac, and about 21% were from government agencies such as Ginnie Mae. The main danger is interest rates. JMBS lost 11.5% in 2022 and 5.43% in the third quarter of 2022 alone. Homeowners can also pay off loans early, which changes the fund's income.
How much does JMBS cost per year?
JMBS charges 0.21% a year, all of it a management fee. Under the SEC's standard example ($10,000 invested, 5% annual return), total costs would be $22 after one year, $68 after three, $118 after five and $268 after ten. That is below the 0.28% average of similar funds, and JMBS ranks 4th of 8 on cost. Index mortgage ETFs such as VMBS (0.03%) and MBB (0.04%) cost less.
