Global ETF assets have climbed to roughly $20 trillion, and one structure is drawing fresh attention: dual share classes, where a single portfolio can be accessed as both a mutual fund and an ETF. Funmi Osiyale, from J.P. Morgan's ETF sales team, sits down with Dimensional’s Joel Schneider and Lauren Olson to explore how the model works and what benefits investors could see — from potential cost savings and tax efficiency to broader access and simpler product lineups. The conversation also covers day-to-day market mechanics, liquidity considerations and what’s next for Dimensional’s ETF platform.
