Fundstrat Capital's Granny Shots US Large Cap ETF (GRNY) just crossed $4 billion in assets, which is pretty remarkable when you consider the fund only launched a little over a year ago. According to data from Morningstar and FactSet, that makes it one of the fastest-growing active equity ETFs out there right now.

The timing tells you something about what investors want in early 2026. They're hunting for equity strategies that don't require a PhD to understand and that actually explain what they're doing. In a market that feels increasingly noisy and uncertain, clarity has become a selling point.

Tom Lee, Fundstrat's chief investment officer, says the fund's growth comes down to its accessible investment philosophy and thematic framework. But he also points to something less sexy and probably more important: regular portfolio updates and weekly videos that walk investors through positioning decisions. When you're charging active management fees, showing your work matters.

The Granny Shots brand seems to have legs beyond the flagship fund. Two ETFs that launched just last November are already pulling in serious money, which suggests investors are buying into the Fundstrat approach more broadly.

The Granny Shots US Small- & Mid-Cap ETF (GRNJ) gathered $255 million in just over a month. That's notable because small and mid-cap stocks have been left in the dust by mega-cap names for years now, and investors are starting to look for catch-up plays. John Bai, Fundstrat's co-founder, said clients had been asking for this kind of targeted exposure for a while. Turns out they weren't just being polite.

Then there's the Granny Shots US Large Cap & Income ETF (GRNI), which has raised $53 million. This one takes the core large-cap strategy and adds an actively managed options overlay to generate income through covered calls. It's designed for investors who want equity exposure but also wouldn't mind collecting some premium along the way. With volatility still elevated and nobody quite sure what the Fed is doing next, that combination has found an audience.

The broader story here is about active management making a comeback, but not just any active management. Investors want strategies they can explain to themselves, delivered by managers who actually communicate. Fundstrat seems to have figured that out, and the asset flows show it.
