Fidelity SAI Enhanced Core Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Fidelity SAI Enhanced Core Bond Fund held 793 positions with $3.08B in net assets. Its ten largest holdings made up 25.4% of the fund. The FECBX share class costs 0.15% a year. Over the 12 months to May 2026, FECBX returned 5.3%, with dividends reinvested. In 2026 Q2 it added 141 new positions and exited 90.
Fidelity SAI Enhanced Core Bond Fund seeks a high level of current income.
The fund invests at least 80% of assets in investment-grade debt securities across all types—corporate bonds, government securities, mortgage-backed securities, loans, and hybrid instruments—using the Bloomberg U.S. Aggregate Bond Index as a structural guide for credit quality and risk characteristics while applying a research-driven approach to identify securities with potential for higher total return. The fund engages in leveraging transactions including derivatives, swaps, and forward-settling securities to adjust risk exposure. Because the fund's security selection depends on manager research rather than index replication, its returns may diverge from the Bloomberg U.S. Aggregate Bond Index.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 76.43% |
| Securitized | 30.19% |
| Cash & short-term | 9.03% |
These positions come to 115.65% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.

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 | 89.8% |
| Floating rate | 10.2% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 5.7% |
| 1-3y | 13.6% |
| 3-5y | 19.0% |
| 5-10y | 15.2% |
| 10y+ | 46.4% |
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
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying nearly 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 | 53% |
| Credit spreads | 47% |
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 | +5.27 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 | 0.02 yr | 0% |
| 1 yr | 0.55 yr | 9% |
| 5 yr | 1.47 yr | 25% |
| 10 yr | 2.13 yr | 36% |
| 30 yr | 1.73 yr | 29% |
| 3 mo | 0.14 yr | 3% |
| 1 yr | 0.90 yr | 17% |
| 5 yr | 1.63 yr | 31% |
| 10 yr | 1.65 yr | 31% |
| 30 yr | 0.95 yr | 18% |
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.
