The State Street SPDR Portfolio Corporate Bond ETF (the Fund) seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of an index that tracks the U.S. corporate bond market.
The fund tracks the Bloomberg U.S. Corporate Bond Index using a sampling strategy, holding a subset of the index's investment-grade corporate bonds selected to replicate the index's risk and return characteristics. Because the fund samples rather than holds all index constituents, its performance may diverge from the index. The fund may also use credit default swaps and related derivatives to obtain index exposure or manage cash flows.

How it has done
SPBO share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.50%. Past returns are a record, not a forecast.
Jun 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 2026-06-30
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 | 100.0% |
Share of the fund's debt value in each maturity band, shortest first.
| 1-3y | 16.4% |
| 3-5y | 17.6% |
| 5-10y | 30.7% |
| 10y+ | 35.4% |
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
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 | 50% |
| Interest rates | 50% |
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 | +6.87 yr |
| High yield | +0.04 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 | 0.01 yr | 0% |
| 1 yr | 0.56 yr | 8% |
| 5 yr | 1.90 yr | 28% |
| 10 yr | 2.76 yr | 40% |
| 30 yr | 1.67 yr | 24% |
| 3 mo | 0.01 yr | 0% |
| 1 yr | 0.56 yr | 8% |
| 5 yr | 1.90 yr | 27% |
| 10 yr | 2.77 yr | 40% |
| 30 yr | 1.67 yr | 24% |
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.
