JPMorgan Core Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, JPMorgan Core Bond Fund held 3,442 positions with $52.83B in net assets. Its ten largest holdings made up 13.2% of the fund. The WOBDX share class costs 0.45% a year. Over the 12 months to May 2026, WOBDX returned 5.0%, with dividends reinvested. In 2026 Q2 it added 78 new positions and exited 228.
The Fund seeks to maximize total return by investing primarily in a diversified portfolio of intermediate- and long-term debt securities.
The fund invests in a diversified portfolio of investment-grade intermediate- and long-term debt securities, including corporate bonds, U.S. Treasuries, agency securities, and mortgage-backed securities, with at least 80% of assets in core bonds (U.S. dollar-denominated, taxable, investment-grade). The adviser selects securities through fundamental analysis of individual issuers and market sectors, evaluating interest rate risk, credit risk, duration, liquidity, and structure, and considers environmental, social and governance factors as part of its risk assessment. The fund's average weighted maturity ordinarily ranges between four and 12 years but may vary under certain market conditions or for temporary defensive purposes. Because security selection depends on the adviser's assessments of individual issuers and market conditions, fund performance will diverge from any benchmark.

How it has done
WOBDX share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.45%. Past returns are a record, not a forecast.
The 8 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.45% | +5.03% | +12.96% | +2.65% | -5.00% | |
| 0.70% | +4.76% | +12.10% | +1.36% | -5.09% | |
| 1.20% | +4.25% | +10.28% | -1.48% | -5.30% | |
| 0.30% | +5.29% | +13.50% | +3.58% | -4.92% | |
| 0.40% | +5.10% | +13.20% | +2.98% | -4.98% | |
| 1.05% | +4.40% | +10.97% | -0.38% | -5.14% | |
| 0.80% | +4.69% | +11.88% | +0.96% | -5.14% | |
| 0.55% | +4.96% | +12.47% | +2.09% | -5.05% |
These classes hold the same portfolio, so the 5.06pp spread over 5 years is the cost difference between them — roughly 1.01pp a year — not a difference in what they own.

Net is what a holder pays after the adviser's contractual waiver; gross is before it. A waiver can expire.
Turnover is how much of the portfolio was replaced in a year.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-05-31
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 73.3% |
| Floating rate | 18.1% |
| Zero-coupon or unclassified | 8.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 3.1% |
| 1-3y | 11.9% |
| 3-5y | 12.3% |
| 5-10y | 31.0% |
| 10y+ | 41.6% |
These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying about half as much.
Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.
| Interest rates | 65% |
| Credit spreads | 35% |
Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.
Share of the fund's spread duration carried by each credit tier.
| Investment grade | +3.14 yr |
| High yield | +0.12 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 1 yr | 0.54 yr | 9% |
| 5 yr | 1.65 yr | 27% |
| 10 yr | 2.35 yr | 39% |
| 30 yr | 1.54 yr | 25% |
3 mo is NEGATIVE (-0.01 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.01 yr | 0% |
| 1 yr | 0.23 yr | 7% |
| 5 yr | 1.16 yr | 36% |
| 10 yr | 1.33 yr | 41% |
| 30 yr | 0.53 yr | 16% |
The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
