TMX Group's acquisition of RAFI Indices from Research Affiliates isn't just about adding a few more products to the shelf. In an interview with MarketDash, Tom Hendrickson, president of TMX VettaFi, laid out how the company plans to use RAFI's fundamental-indexing expertise, combined with its own tech and distribution muscle, to make a bigger splash in the ETF and institutional indexing world.

The deal brings more than 90 RAFI indices, over 40 ETFs, and more than $90 billion in ETF assets under TMX VettaFi's roof, according to Hendrickson. When you factor in global benchmarks and institutional mandates, RAFI represents about $182 billion in Assets Under Indexing (AUI). That's a lot of money tracking these strategies.

"RAFI pioneered fundamental indexing by weighting companies by economic footprint, such as sales or cash flow, rather than market capitalization," Hendrickson said. "RAFI brought world-class institutional research and factor methodologies that squarely fit into TMX VettaFi's strategy and accelerate our growth trajectory."

The transaction takes TMX VettaFi's overall indexing platform from roughly $81 billion to $263 billion in pro-forma AUI, based on first-quarter 2026 figures. That's a big jump, and it signals a clear intent to be a major player in the index space.

From Market-Cap Weighting to Economic Fundamentals

The deal comes at a time when ETF issuers are increasingly looking beyond the traditional market-cap-weighted benchmarks. They want something that stands out, something that isn't just a mirror of the S&P 500.

Hendrickson says market concentration has been a key driver of this demand. "High market concentration in traditional market-cap benchmarks has driven strong demand for fundamentally weighted indices that rebalance based on actual economic footprints rather than price momentum," he explained.

He added that issuers are increasingly looking for "disciplined valuation, sales, and cash-flow screens to manage downside risk," while also incorporating income-generation capabilities into core portfolios. In other words, they want strategies that can hold up when the market gets shaky.

But don't expect VettaFi to mess with what's working. "Our strategy is to preserve the flagship RAFI index suite completely intact," Hendrickson said. "We are focused on investing additional resources to expand distribution, increase research visibility, and accelerate client access across global markets rather than consolidating or retiring existing strategies."

For existing clients, the transition should be seamless. "It is business as usual for all client relationships," Hendrickson noted, with existing licensing agreements and index-governance frameworks remaining intact.

Where the ETF Opportunity Lies

The real opportunity might be in taking RAFI's established strategies to new investors and new markets. "Combining RAFI's factor and fundamental strategies with TMX VettaFi's calculation and distribution infrastructure accelerates new product commercialization," Hendrickson said.

He pointed to active discussions about bringing RAFI strategies into Europe, the Middle East and Africa, and Asia, while also expanding access to value, income, and factor-based strategies among institutional asset owners and wealth-management platforms. That's a global push.

Hendrickson also sees a chance to use VettaFi's distribution network to give RAFI strategies more visibility. "By pairing RAFI's suite with TMX VettaFi's digital network—reaching over 1.9 million monthly site visitors and 90,000+ financial advisors annually—we can actively support their products, doubling down on distribution, and drive broader education around RAFI strategies," he said.

And there's more: VettaFi has over 250,000 investor behavioral profiles, which Hendrickson says can help issuers align RAFI-linked products with what advisors actually want. That's a data advantage that could pay off.

From RAFI Indexes to Next-Generation Strategies

The acquisition could ultimately go beyond just distributing the existing RAFI lineup. When asked whether VettaFi could combine RAFI's methodologies with its own data and technology to create products neither business could have developed alone, Hendrickson's answer was a straightforward "Yes."

"Fusing RAFI's fundamental weighting methodologies with TMX VettaFi's real-time advisor engagement data, analytics, and Index Factory calculation engine enables next-generation index design," he said.

The standalone RAFI index suite will stay intact, but the two businesses are expected to collaborate on new strategies. "Cross-pollination will drive joint innovation," Hendrickson said, adding that VettaFi will draw on RAFI's factor research and fundamental screening models to develop multi-asset, thematic, and custom index strategies for global asset managers.

That combination might be the most significant part of the deal. It's not just about adding 90-plus indexes to the platform; it's about merging RAFI's research with VettaFi's technology, advisor data, and distribution capabilities. As Hendrickson put it, the goal is to create a "far more powerful set of tools and analytics" for the company's global client base.

So, what does this mean for the average investor? It means more options, potentially. More ETFs that aren't just cap-weighted, more strategies that focus on fundamentals, and more ways to play value, income, and factors. And with VettaFi's distribution, these products could get more attention from advisors and investors alike. It's a bet that fundamental indexing has a bright future, and TMX VettaFi wants to be at the center of it.
