ETFs were once almost synonymous with low-cost, sensible investing. But that era is changing fast. In this episode, Ben Felix, Dan Bortolotti, and Ben Wilson introduce and unpack the concept of “ETF slop”—the explosion of complex, high-fee, behaviorally engineered ETFs that are designed to attract assets rather than improve investor outcomes. The trio traces how ETFs evolved from simple index-building tools into wrappers for increasingly speculative strategies. They discuss how the ETF “halo effect” can mislead investors into equating structure with quality, and why innovation in financial products often benefits manufacturers more than end investors. From thematic hype to downside “protection” that isn’t what it seems, the episode offers a clear framework for thinking critically about modern ETF offerings.
