A relentless barrage of headlines in recent weeks have all centered on exchange-traded funds. For the first time, there are now more ETFs than stocks (4,300 versus 4,200). Also of note, ETFs have also become prized listings for exchanges—perhaps even more than IPOs—because they trade so much.

On this episode of Trillions, Eric Balchunas and Joel Weber speak with Dave Nadig, president and director of research at ETF.com, and Athanasios Psarofagis, an analyst with Bloomberg Intelligence. They discuss those stories as well those on passive ownership's increasing complexity; a different way to think about the Magnificent Seven; Vanguard's push into active management; Wall Street not seeing a need for tokenization; and the irony of European ESG equity funds having exposure to the nuclear arms industry.
