Lord Abbett Ultra Short Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Lord Abbett Ultra Short Bond Fund held 643 positions with $16.55B in net assets. Its ten largest holdings made up 9.0% of the fund. The LUBAX share class costs 0.44% a year. Over the 12 months to May 2026, LUBAX returned 4.2%, with dividends reinvested. In 2026 Q2 it added 144 new positions and exited 133.
The Funds investment objective is to seek current income consistent with the preservation of capital.
The fund invests in short-duration, investment-grade debt securities across corporate, government, mortgage-backed, and asset-backed instruments, with a focus on relative value; it concentrates more than 25% of assets in the financial services industry under normal conditions. The portfolio management team employs top-down macroeconomic analysis combined with bottom-up security selection to identify undervalued opportunities, and may actively rotate sector exposure and trade frequently. Because the fund purchased securities rated investment grade may subsequently be downgraded to below-investment-grade status, it may hold junk bonds involuntarily. The fund is not a money market fund and does not guarantee a stable share price despite its short-term focus.

How it has done
LUBAX share class · total returns with dividends reinvested
Volatility over the last 12 months: 0.43%. Past returns are a record, not a forecast.
The 7 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.44% | +4.24% | +16.66% | +18.81% | 0.00% | |
| 0.39% | +4.27% | +16.84% | +19.04% | 0.00% | |
| 0.29% | +4.37% | +17.19% | +19.77% | 0.00% | |
| 0.29% | +4.37% | +17.20% | +19.67% | 0.00% | |
| 0.24% | +4.46% | +17.36% | +19.90% | 0.00% | |
| 0.24% | +4.46% | +17.36% | +20.01% | 0.00% | |
| 0.54% | +4.11% | +16.20% | +18.17% | 0.00% |
These classes hold the same portfolio, so the 1.84pp spread over 5 years is the cost difference between them — roughly 0.37pp a year — not a difference in what they own.

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 | 72.2% |
| Floating rate | 27.0% |
| Zero-coupon or unclassified | 0.8% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 19.3% |
| 1-3y | 60.8% |
| 3-5y | 6.4% |
| 5-10y | 6.8% |
| 10y+ | 6.7% |
Based on what filers reported; a filer that never reported a flag also reads as none.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.
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.
| Credit spreads | 51% |
| Interest rates | 49% |
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 | +0.68 yr |
| High yield | +0.06 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 3 mo | 0.11 yr | 15% |
| 1 yr | 0.51 yr | 72% |
| 5 yr | 0.09 yr | 12% |
| 10 yr | 0.00 yr | 0% |
| 30 yr | 0.00 yr | 0% |
| 3 mo | 0.11 yr | 15% |
| 1 yr | 0.52 yr | 71% |
| 5 yr | 0.09 yr | 13% |
| 10 yr | 0.01 yr | 1% |
| 30 yr | 0.00 yr | 0% |
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.
