Lord Abbett Short Duration High Yield Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Lord Abbett Short Duration High Yield Fund held 645 positions with $9.95B in net assets. Its ten largest holdings made up 9.8% of the fund. The LSYUX share class costs 0.38% a year. Over the 12 months to May 2026, LSYUX returned 8.9%, with dividends reinvested. In 2026 Q3 it added 192 new positions and exited 136.
The Funds investment objective is to seek a high current income and the opportunity for capital appreciation to produce a high total return.
The fund invests at least 80% of assets in high-yield debt securities rated BB/Ba or lower, selecting securities through bottom-up credit analysis with the goal of identifying lower-rated debt where credit risk is expected to decline. The fund manages interest rate risk by maintaining a weighted average duration of three years or less and may use derivatives to adjust interest rate exposure or enhance returns. Because security selection depends on the portfolio manager's assessment of individual issuers' credit trajectories and market conditions, results will diverge from any benchmark.

How it has done
LSYUX share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.30%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 9 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.38% | +8.94% | +31.53% | +31.15% | -2.75% | |
| 0.45% | +8.87% | +31.27% | +30.78% | -2.75% | |
| 0.70% | +8.57% | +30.27% | +29.13% | -2.79% | |

| 1.39% | +7.87% | +27.73% | +24.98% | -2.91% |
These classes hold the same portfolio, so the 6.33pp spread over 5 years is the cost difference between them — roughly 1.27pp 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 2026-04-30
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 | 93.7% |
| Floating rate | 5.7% |
| Zero-coupon or unclassified | 0.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.9% |
| 1-3y | 24.3% |
| 3-5y | 59.4% |
| 5-10y | 11.1% |
| 10y+ | 3.3% |
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
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 | 55% |
| Interest rates | 45% |
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.
| High yield | +2.38 yr |
| Investment grade | +0.26 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 | 0.05 yr | 2% |
| 1 yr | 0.87 yr | 40% |
| 5 yr | 1.26 yr | 58% |
| 10 yr | 0.01 yr | 0% |
| 30 yr | 0.00 yr | 0% |
| 3 mo | 0.04 yr | 2% |
| 1 yr | 0.95 yr | 36% |
| 5 yr | 1.51 yr | 57% |
| 10 yr | 0.08 yr | 3% |
| 30 yr | 0.05 yr | 2% |
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.

Duration contribution in years, summing to the fund's 2.20 yr.
This is where the fund's rate exposure sits, not its currency risk — most international bond funds hedge the currency back to dollars, and the size of those hedges is not in the filing. Tenors are also summed across curves, so a 5-year JPY point and a 5-year USD point are added together.
