Sep 10, 2026 · 24m

Summary

Hosts Joel Weber and Eric Baltunas discuss Vanguard’s 50th anniversary of the index fund with guest Isabel Lee. They analyze how Vanguard’s market share has plateaued, fulfilling Jack Bogle’s 1991 prediction that his mission was complete when competitors adopted low-cost models. The episode explores Bogle’s "addition by subtraction" philosophy, comparing his ethos to punk rock’s minimalism. They also examine the industry’s shift, noting that while core index funds are now loss leaders, the "Bogle Effect" has driven innovation in exotic ETFs and forced rivals like Fidelity to compete on price.
