Fund profile
As filed in the prospectus · 2026 Q2
Fidelity High Income Fund seeks a high level of current income. Growth of capital may also be considered.
The fund invests primarily in below-investment-grade debt securities, preferred stocks, and convertible securities, using the ICE BofAUS High Yield Constrained Index as a guide to its credit quality composition. The fund may also hold non-income-producing securities, including defaulted securities and common stocks, and invests in companies in troubled or uncertain financial condition. Because the fund's selection depends on fundamental analysis of each issuer's financial condition and industry position rather than mechanical index tracking, its credit quality composition may diverge from the index it uses as a reference.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Bonds | 83.06% |
| Cash & short-term | 16.62% |
| Loans | 8.33% |
| Stocks | 3.78% |
| Securitized | 0.01% |
These positions come to 111.81% 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%.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Other | 39.6% |
| Cash | 14.9% |
| International | 14.0% |
| Energy | 4.2% |
| 12 smaller | 27.4% |
Government, Securitized and Cash are non-corporate buckets; International is foreign holdings we don’t sector-classify, and Other is the residual (held funds, unresolved names).

| +11.84% | -46.54% | -81.24% | 3.54% | -52.20% |
These classes hold the same portfolio, so the 105.79pp spread over 5 years is the cost difference between them — roughly 21.16pp 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 | 86.0% |
| Floating rate | 14.0% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.8% |
| 1-3y | 16.8% |
| 3-5y | 33.2% |
| 5-10y | 43.0% |
| 10y+ | 5.2% |
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 | 54% |
| Interest rates | 46% |
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 | +2.94 yr |
| Investment grade | +0.67 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 | 0.03 yr | 1% |
| 1 yr | 0.58 yr | 19% |
| 5 yr | 1.75 yr | 57% |
| 10 yr | 0.62 yr | 20% |
| 30 yr | 0.06 yr | 2% |
| 3 mo | 0.51 yr | 14% |
| 1 yr | 1.35 yr | 38% |
| 5 yr | 1.40 yr | 39% |
| 10 yr | 0.28 yr | 8% |
| 30 yr | 0.06 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.
