What if the index fund you thought was simple was actually shaped by a complex set of rules, decisions, and trade-offs? In this episode, we sit down with Rob Harvey, Co-Head of Product Specialists and Vice President at Dimensional Fund Advisors, to unpack what indexing really means. You’ll learn how indexes are constructed, who actually makes the rules, how index funds are managed, and why “passive” investing may not be as passive—or straightforward—as it sounds.
Listen in to hear why different indexes tracking the same part of the market can produce dramatically different results, what fees and tracking error mean for investors, and how rules around rebalancing, free float, profitability, and company size can affect what you actually own. Using real-world examples, including SpaceX and small-cap indexes, this episode will help you look beyond the label and better understand the investments sitting in your portfolio.
