Fund profile

As filed in the prospectus · 2025 Q4

Fidelity Total Bond Fund seeks a high level of current income.

Strategy · summarised

The fund invests at least 80% of assets in debt securities across investment-grade, high yield, and emerging markets, selecting securities by analyzing credit quality, valuation, and economic risks while managing overall interest rate risk to align with the Bloomberg U.S. Aggregate Bond Index. The fund may allocate up to 20% to below-investment-grade debt and uses derivatives and leverage to adjust risk exposure. Because security selection depends on the manager's credit analysis and valuation judgments, fund returns will diverge from the index.

In arrears: 0.09% · $41.09M · 34 positions

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 2026Q1

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.

Interest-rate duration
5.54 yr
approx. move per 100bp
Credit-spread duration
5.97 yr
approx. move per 100bp
If rates and spreads both rise 100bp

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.

of value
Credit spreads52%
Interest rates48%

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 duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.

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.
