Episode 330 - Davidson Heath: How Are Index Funds Affecting Financial Markets and Corporate Governance?
The Rational Reminder Podcast
Impact of Stock Sampling on ETF Arbitrage and Market Dynamics
This chapter explores how authorized participants engage with ETFs through arbitrage and the consequences of including various stocks in the ETF's basket. It highlights the effects on market liquidity, volatility, and the crucial role of sampling replication for long-term investors.
What happens when index investing dominates the market? In this episode, we’re joined by Davidson Heath, Assistant Professor of Finance at the University of Utah David Eccles School of Business, to explore this question and its surprising answers. Davidson’s research dives into the unintended impacts of passive investing, examining how it influences price stability, corporate governance, and even the way we define shareholder responsibility. He unpacks how index funds, while supporting price efficiency, may be weakening governance structures by reducing shareholder oversight, a shift that could have lasting effects on corporate accountability. We also discuss the promise and limitations of socially responsible investing (SRI), as Davidson introduces the term “impact washing” to describe how some SRI funds fail to achieve real change despite their green branding. In a forward-looking segment, Davidson shares insights on the collaboration between AI and human intelligence in finance, giving a reassuring perspective on the future of machine and human co-existence in complex decision-making. This episode is a must-listen for anyone curious about the hidden dynamics of passive investing and the evolving role of technology in finance!
