Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The Fund outperformed the Primary Index during the reporting period, driven by positive contributions from both allocation and security selection. Relative performance was supported primarily by strong bond selection and the Fund’s allocation to CLOs.

Loan selection detracted modestly from relative performance, although the Fund’s lower allocation to loans helped partially offset the impact.

At the sector level, relative performance was supported by positive contributions from Energy, Financial Services, and Consumer Discretionary Distribution & Retail. This was partially offset by weakness in Software & Services, where both allocation and selection detracted from relative results.

On an issuer level, the leading contributors to the Fund’s total return during the reporting period were Michaels Cos, Inc., CHS/Community Health Systems, Inc., and PBF Holding Co. LLC. / PBF Finance Corp.. The largest detractors from the Fund’s total return during the reporting period were First Brands Group, LLC., Cast & Crew, LLC., and CSC Holdings, LLC..

Performance Past Does Not Indicate Future [Text]

The Fund’s past performance is not necessarily an indication of how the Fund will perform in the future. The returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or on the redemption or sale of Fund shares.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The Fund outperformed the Primary Index during the reporting period, driven primarily by favorable asset allocation, including exposure to bonds, CLOs and equity, which contributed positively versus the benchmark.

The Fund benefited from exposure across a broader range of capital structure, with senior unsecured, senior secured, second line and CLO investments contributing positively and helping to offset weakness in first lien loans.

At the sector level, relative performance was supported most meaningfully by Consumer Discretionary Distribution & Retail, alongside positive contributions from Media & Entertainment and Health Care Equipment & Services, partially offset by weakness in Software & Services.

On an issuer level, the top contributors to the Fund’s total return during the reporting period were Michaels Cos, Inc., Asurion LLC., and Gainwell Acquisition Corp.. The top detractors were First Brands Group LLC., Cast & Crew LLC. and Ivanti Software, Inc..

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Over the reporting period, emerging markets (EM) sovereign and corporate debt delivered strong returns despite the continued rise in U.S. Treasury yields. While both sectors posted solid performance, EM sovereigns significantly outperformed, led by the high yield segment, which benefited from improving risk sentiment and attractive carry.

The primary driver of the Fund's underperformance was asset allocation. The Fund maintained an underweight allocation to high yield credit relative to the Index, which detracted from performance as these assets outperformed amid strong investor demand and continued spread tightening. Conversely, the Fund's allocation to sovereign and quasi-sovereign debt contributed to returns, benefiting from meaningful spread compression over the period. From a regional perspective, the Fund's underweight exposure to Africa and Europe - the strongest-performing regions in the Index - also weighed on relative performance. These detractors were partially offset by the Fund's underweight to the Middle East and Asia, which were the weakest-performing regions during the reporting period. The Fund ended the period with a slightly shorter duration than the Index.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The primary driver of outperformance was duration positioning as the Fund maintains a slightly shorter duration than the Index as interest rates broadly sold off over the period. The Fund continues to maintain a higher credit allocation than the Index with a roughly sixty-five percent weighting to credit risk sectors, compared to approximately thirty percent in the Index.

The Fund’s best performing sector was Agency MBS as the sector experienced outsized investor demand amid heightened geopolitical uncertainty and resilient housing fundamentals. Investment grade corporates also delivered strong performance, as credit spreads on corporate assets tended to tighten over the period.

Every sector within the portfolio generated a positive return. The greatest contribution to the Fund’s performance during the period was U.S. Treasurys. No sector detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The primary driver of Fund underperformance was the U.S. Treasury allocation, as the Fund expressed a view of a steepening yield curve over the period. The Fund maintained a slightly shorter duration than the Index.

The Fund’s best performing sector was high yield bonds as these assets significantly outperformed their investment grade counterparts because of material credit spread tightening in lower rated credits. Agency and non-Agency MBS also delivered strong performance as these assets experienced outsized investor demand amid heightened geopolitical uncertainty and resilient housing fundamentals.

The greatest contribution to the Fund’s performance during the reporting period was Agency MBS. The only sector to detract from overall Fund performance was U.S. Treasuries. Within the U.S. Treasury allocation, the Fund expressed a view of a steepening yield curve with an overweight to the two-year tenor and an underweight to the 30-year tenor when compared to the Agg.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

U.S. high yield corporate spreads tightened over the period as the sector was aided by solid fundamentals and ultimately softening inflation despite recent headline volatility. Within the portfolio, our allocation to the sector positively contributed to absolute performance. Technology, consumer cyclical, and capital goods names were mostly responsible for the positive impact on return.

U.S. investment grade corporate bonds performed well as spreads also tightened over the period. Despite headwinds related to massive A.I.-driven issuance, resilient economic data remained supportive overall. Within the portfolio, investment grade corporates contributed to absolute performance. Financial, particularly banking, names were primarily responsible for the positive impact.

Bank loans also showed resilience, as geopolitical developments tempered expectations for lower policy rates. For the portfolio, our allocation to bank loans aided absolute performance, with individual capital goods issues adding in particular.

The use of derivatives instruments within the Fund had a negative impact. This effect is attributed mainly to long exposure to interest rate futures.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

During the past year, the municipal market rallied, although faced volatility as U.S. federal policy and geopolitical risk adjusted spread and risk premiums. The Fund’s longer duration positioning was a positive driver of performance, particularly in 8+ year duration bonds. The Fund’s overweight exposure in unrated bonds and underweight to bonds rated double-A aided performance. Sector exposure hurt performance, including an overweight in electric, transportation and special tax revenue bonds. Selection also hurt performance as certain credits meaningfully underperformed the market.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The 12-month period ended June 30, 2026, was characterized by significant geopolitical risks but resilience across global economies and capital markets. The level of interest rates was generally range bound over the period. By contrast, the U.S. yield curve steepened over the first half of the period as the U.S. Federal Reserve (the "Fed") was engaged in an easing policy cycle before steadily flattening as inflation risks picked up during the U.S.-Iran War and the market grew hawkish in and around a leadership transition at the Fed. Credit spreads ebbed and flowed alongside market risk sentiment but generally finished modestly tighter than where they started. The Fund underperformed its benchmark over the reporting period. While investment positions changed throughout the year, tactical positions taken in long term government bonds and underweight allocations to intermediate term corporate bonds generally detracted from performance. The impact of these positions were partially offset by an overweight held in longer term corporate bonds and by having less exposure to intermediate government bonds.

Material Fund Changes

Effective October 31, 2025, the Fund’s name changed from the SPDR^® SSGA Fixed Income Sector Rotation ETF to the State Street^® Fixed Income Sector Rotation ETF. This change did not result in any changes to the Fund’s Investment Objective, Principal Investment Strategies or Principal Risks of Investing in the Fund.

Effective on June 23, 2026, the Fund’s investment objective changed from "seeking to provide total return by focusing on investments in income and yield-generating assets" to "seeking to maximize risk-adjusted return and provide current income".

Effective on June 23, 2026, the Fund’s principal investment strategy was updated to (1) allow allocation of its assets among ETFs that focus on asset-backed securities; (2) utilize rigorous fundamental research to invest in individual fixed income securities for risk management and security exposure management purposes; (3) employ a risk-aware, top-down allocation approach that seeks to overweight the Fund’s exposure to the most attractive Fixed Income Sectors; and (4) use derivative instruments to hedge currency exposure and manage yield, interest rate exposure (also known as duration), and credit quality exposure. Additionally, corresponding principal risks were updated to reflect these changes.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The 12-month period ended June 30, 2026 was characterized by significant geopolitical risks but resilience across global economies and capital markets. The Fund delivered healthy returns but given its diversified approach it did not meet the performance of its all-equity benchmark (MSCI ACWI IMI). The Fund held an overweight to global equities for the majority of the period as the risk environment was mostly calm, with the exception of the energy shock associated with the U.S.-Iran War, and corporate earnings were consistently strong. Additionally, the Fund maintained an overweight position in broad commodities as trends in those real asset markets picked up in late 2025 and that investment helped to add value and mitigate risk during the energy shock. The Fund’s regional equity allocations detracted from performance over the reporting period. The Fund generally favored U.S. equities over non-U.S. developed equities and domestic markets lagged during the 1st quarter of 2026 amidst a flurry of geopolitical pronouncements and risks emanating from the U.S. administration, which led to a weaker U.S. dollar and relatively weaker U.S. stock markets.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The 12-month period ended June 30, 2026, was characterized by significant geopolitical risks but resilience across global economies and capital markets. The Fund delivered double digit returns but given its diversified approach it could not keep pace with its primary benchmark (MSCI World Index), however it was able to handily outperform its secondary benchmark. The Fund held an overweight to global equities for the majority of the period as the risk environment was mostly calm, with the exception of the energy shock associated with the U.S.-Iran War, and corporate earnings were consistently strong. These overweights were taken mostly at the expense of underweights to broad U.S. Treasuries and investment grade corporate bonds. Together, the tactical decisions to overweight equities and underweight bonds were additive over the period as was the decision to overweight U.S. versus non-U.S. equities. In terms of detractors, the decision to underweight U.S. REITs and overweight U.S. high yield bonds negatively impacted performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The Fund benefited from strong performance across real assets, particularly metals and energy. Early in the year, expectations for interest rate cuts and resilient economic growth supported returns, with the Fund gaining approximately 10.5%, led by Metals & Mining. Performance drivers shifted in the second half as geopolitical tensions in the Middle East disrupted energy markets. The closure of the Strait of Hormuz drove oil prices sharply higher and boosted energy-related assets. Oil prices later retreated after de-escalation and a Memorandum of Understanding between the U.S. and Iran, but the Fund still gained approximately 10.8% during the period. For the year, the Fund's diversified exposure to real assets outperformed a traditional inflation-linked fixed income benchmark, the Bloomberg U.S. Government Inflation-Linked Bond Index and was on par with the broad DBIQ Optimum Yield Diversified Commodity Index Excess Return. From an allocation perspective, overweight positions in commodities and natural resources, along with an underweight to inflation-linked bonds, contributed positively to results, while the underweight to REITs and overweight positions in cash and infrastructure equities modestly detracted from performance.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

During the first half of the reporting period, softness in the labor market led to three 25bps U.S. Federal Funds ("Fed Funds") rate cuts and moderately tighter investment-grade credit spreads. In 2026, conflict in the Middle East led to a spike in oil prices and inflation expectations, the potential for Fed Funds rate hikes, and, as a result, a significant increase in interest rates and moderately tighter investment-grade credit spreads. The Fund’s over-weight allocation to duration was the primary driver of the Fund’s under-performance of the Index during the reporting period, while the Fund’s over-weight allocation to investment-grade credit contributed to relative performance. The Fund reduced its duration from 0.90 to 0.75 during the reporting period. The Fund used treasury futures to actively manage duration during the reporting period. The Fund’s use of treasury futures detracted from Fund performance relative to the Index.

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

The twelve-month period was characterized by strong absolute performance, but the Fund underperformed its benchmark for the reporting period. Relatively strong performance during the second half of 2025 was offset by a more challenging first half of 2026. The Fund generated strong absolute and relative returns during the second half of 2025, driven primarily by overweight positions in Communication Services and Health Care. Market leadership remained concentrated in A.I. related companies, benefiting Communication Services, while improving sentiment toward pharmaceutical and biotechnology companies supported strong Health Care performance during the fourth quarter. Performance was more challenging during the first half of 2026. The portfolio entered the year underweight Energy, which proved costly as the sector rallied during the first quarter amid tensions in the Middle East. In April, an overweight to Health Care detracted as the market rebounded and investors rotated toward growth sectors. As the quarter progressed, although Communication Services contributed positively to returns, the portfolio overweight became a relative headwind as market leadership broadened and investors rotated into Financials and other cyclical sectors.
