Fund profile
As filed in the prospectus · 2025 Q4
Fidelity Short-Term Bond Index Fund seeks to obtain a high level of current income consistent with preservation of capital.
The fund tracks the Bloomberg U.S. 1-5 Year Government/Credit Bond Index using statistical sampling, holding a smaller number of securities selected to replicate index returns while maintaining a dollar-weighted average maturity of three years or less. Because the fund samples rather than holds all index constituents, its returns may diverge from the index. The fund may use derivatives including swaps, options, and futures to adjust risk exposure.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
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 | 91.7% |
| Floating rate | 8.3% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 2.0% |
| 1-3y | 53.4% |
| 3-5y | 42.9% |
| 5-10y | 1.4% |
| 10y+ | 0.2% |
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 | 52% |
| Interest rates | 48% |
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 | +2.71 yr |
| High yield | +0.00 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 | 0.00 yr | 0% |
| 1 yr | 1.10 yr | 44% |
| 5 yr | 1.43 yr | 56% |
| 30 yr | 0.00 yr | 0% |
10 yr is NEGATIVE (-0.00 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.12 yr | 4% |
| 1 yr | 1.23 yr | 45% |
| 5 yr | 1.36 yr | 50% |
| 10 yr | 0.00 yr | 0% |
| 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.
