Fidelity Sustainable U.S. Equity ETF (FSST) is an exchange-traded fund that seeks to provide investment results corresponding to the performance of the Fidelity U.S. Sustainable Equity Index before fees and expenses. The fund invests at least 80% of its assets in equity securities included in the index, which comprises U.S. companies selected for their strong sustainability practices alongside financial criteria such as market capitalization and liquidity; these securities span large-, mid-, and small-cap stocks across diverse sectors including technology, healthcare, consumer discretionary, and industrials. FSST offers investors exposure to approximately 230 holdings with a focus on environmental, social, and governance (ESG) factors, utilizing proprietary Fidelity research to evaluate sustainability metrics like carbon emissions, board diversity, and labor practices alongside traditional fundamental analysis.
Launched in 2023 and managed by Fidelity Management & Research Company LLC, headquartered in Boston, Massachusetts, FSST operates primarily in the U.S. equity market, targeting institutional and retail investors interested in sustainable investing strategies. The fund employs a passive indexing approach with quarterly rebalancing to maintain alignment with the benchmark, which excludes companies involved in controversial activities such as tobacco, weapons, and fossil fuels; it also applies revenue-based screens to further emphasize sustainability. Geographically, FSST focuses exclusively on U.S.-domiciled companies, providing broad domestic market exposure without international allocations.
In recent developments, FSST benefited from Fidelity's broader strategic expansion into sustainable investing, including enhancements to its ESG indexing methodology in 2024 to incorporate forward-looking climate risk assessments and biodiversity impacts. The fund saw increased assets under management amid rising demand for ESG products, surpassing $100 million AUM by mid-2025 following Fidelity's launch of complementary sustainable ETFs and partnerships with index providers to refine sustainability data integration. No major acquisitions or name changes have occurred, but Fidelity announced operational enhancements in late 2024, such as improved transparency reporting and integration of AI-driven ESG analytics to bolster portfolio resilience.
