Episode notes
In this special 400th episode, the Rational Reminder hosts reflect on 50 years of index investing and the profound impact it has had on financial markets, investor behavior, and the cost of investing. The episode features a panel moderated by Ben Felix at the New York Stock Exchange - hosted by Vanguard and S&P Dow Jones Indices - bringing together leading voices in the indexing world to explore how passive investing evolved and what it means for the future of capital markets. Ben is joined on the panel by Tim Edwards (S&P Dow Jones Indices), Jim Rowley (Vanguard), and Shelly Antoniewicz (Investment Company Institute) to discuss the mechanics of indexing, the myths surrounding passive investing, and the evidence on how index funds affect markets. They unpack questions about market concentration, price discovery, and whether indexing is changing the structure of capital markets.
