What this fund is
Objective, as filed

Fidelity Total Bond ETF 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, allocating across maturities and sectors while managing interest rate risk to track the Bloomberg U.S. Aggregate Bond Index. Up to 20% may be held in high yield debt. The fund uses derivatives including swaps, options, and futures to adjust risk exposure. Because security selection depends on the manager's analysis of credit quality, valuation, and trading opportunities rather than index replication, fund returns may diverge from the benchmark.

What the fund is made of

Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.

106.11%
of net assets
Bonds65.93%
Securitized29.91%
Loans5.12%
Cash & short-term4.79%
2 smaller0.37%

These positions come to 106.11% 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%.

Derivatives are shown at market value, not notional exposure.

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.

5.64 yr
approx. move per 100bp
6.07 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.

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.

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.
