Episode notes
What if index funds weren't as "passive" as you think? In this episode of the Rational Reminder, we are joined by Jim Rowley, Global Head of Investment Implementation Research, and Andy Mack, Head of US Equity Portfolio Management at Vanguard. These two experts offer a rare, behind-the-scenes look into what it really takes to run some of the world's largest index funds - and it's far from "set it and forget it." From real-time trading decisions to managing $7 trillion globally, Jim and Andy walk us through how Vanguard implements index strategies with a precision that rivals any active manager. They challenge the traditional labels of passive versus active and show how thoughtful implementation, securities lending, FX execution, and IPO participation can add real value for investors - even in low-cost index products.
