Guinness Atkinson Funds SmartETFs Sustainable Energy II ETF (SOLR) is an actively managed exchange-traded fund that invests primarily in global equity securities of companies positioned to benefit from the transition to sustainable energy. The ETF focuses on firms that provide or support alternative or renewable energy sources, including those involved in generation, production, storage, transportation, delivery, or efficiency enhancements for solar, wind, hydro, geothermal, biofuels, biomass, and related technologies; key holdings encompass semiconductors like ON Semiconductor and Infineon Technologies, energy equipment providers such as Hubbell and Schneider Electric, utilities including Iberdrola, and manufacturers like First Solar and LG Chem, typically maintained in a concentrated portfolio of around 33 roughly equal-weighted positions with at least 80% of net assets allocated to such sustainable energy companies. Headquartered in Pasadena, California, through its investment adviser Guinness Atkinson Asset Management, Inc., founded in 2002, the fund operates with a global mandate targeting institutional and retail investors seeking exposure to thematic energy innovation and trades on the NYSE Arca exchange.
In recent developments, the fund declared its annual distribution of $0.2077 per share in December 2025, reflecting ongoing shareholder returns amid a net expense ratio of 0.79% and assets under management of approximately $4 million. Operationally, SOLR transitioned from the ticker SULR on the Cboe to the NYSE Arca exchange in January 2022 to align with Guinness Atkinson's broader ETF lineup, while its underlying strategy continues to mirror the long-standing Guinness Atkinson Alternative Energy mutual fund launched in 2006. No major acquisitions, funding rounds, or partnerships directly impacting SOLR have been reported in the last 1-2 years, though the broader Guinness organization expanded into European markets in 2024 via a strategic collaboration with HANetf to manage the Guinness Sustainable Energy UCITS ETF (CLMA), applying a parallel active sustainable energy approach.
