The State Street SPDR Portfolio Short Term Treasury 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 short term sector of the United States Treasury market.
The fund tracks the Bloomberg 1-3 Year U.S. Treasury Index using a sampling strategy, holding a subset of the index's short-term Treasury securities selected to match the index's risk and return characteristics. The fund invests at least 80% of assets in index constituents and may also hold Treasury securities outside the index, cash, and money market instruments for cash management. Because the fund samples rather than holds all index securities, its performance may diverge from the index.

How it has done
SPTS share class · total returns with dividends reinvested
Volatility over the last 12 months: 1.17%. 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.

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
This fund filed the credit-spread disclosure and reported no sensitivity — measured, and the answer is none.
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 | 100% |
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.
