Investing With Purpose: Defiance Launches Autism Impact ETF

Ben HernandezJun 03, 2026
2026-06-03

With over 5,000 funds and many launching daily in the exchange-traded fund (ETF) universe, there are a select few that can capture both industrial utility and deep human significance. One of those ETFs launched with the introduction of the Defiance Autism Impact ETF (ASD) from Defiance ETFs — a leader in thematic and income-focused ETFs since 2018.

Given its focus, the launch presents a milestone for the asset management community. ASD blends a sophisticated index design with structural corporate philanthropy to create an ETF that resonates with those invested financially and emotionally.

“As a person, not just an ETF analyst, this makes me proud,” TMX VettaFi Head of Research Todd Rosenbluth wrote ahead of the launch, citing his own personal experience with an autistic family member. “While ETFs seem to launch on a daily basis, this one will be on my radar.”

Investment Strategy

The Fund utilizes a passive indexing approach that tracks the total return performance of the VettaFi Autism Impact Index. This Index specifically targets publicly traded global companies in developed markets that support the autism and broader neurodivergent ecosystem.

Eligible “Autism Impact Companies” must demonstrate material involvement across three core thematic pillars: drugs & behavior therapeutics, diagnostics & assessment tools, or specialized education & educational technology. More specifically, these companies include those that operate across healthcare, pharmaceuticals, biotechnology, behavioral services, diagnostics, specialized education, and assistive technologies.

Constituents are screened according to public filings, revenue segmentations, and clinical trials. For inclusion in the Index, companies must maintain a minimum market capitalization of $250 million and a three-month average daily trading value of $1 million. The Index, which is equally weighted, is reconstituted semi-annually (in June and December) and rebalanced on a quarterly basis (March, June, September, and December).

Supporting Neurodivergent Community

The fund notably features a voluntary impact-investing mandate that donates 100% of its net advisory profits during the first two years. After the two-year windows has expired, Defiance will continue donating at least 50% to support organizations involved in autism care, research, and neurodivergent resources.

“As parents of a profoundly autistic child, this launch is deeply personal to our family,” said Matthew Bielski, CEO of Defiance ETFs, and Gabriella Zahn-Bielski, general counsel of Defiance ETFs. “Families impacted by autism face challenges every single day, and after experiencing that firsthand, we became committed to helping drive greater awareness, innovation, research, and support for the autism community. Our hope is that the ASD ETF can help direct more long-term capital and investment toward companies and organizations working to improve quality of life for individuals with autism and their families.”
