Deep dives

Impact of Index Funds on Market Efficiency

Index funds have a significant influence on price efficiency in financial markets. As the market share of passive investing increases, active managers, who traditionally enhance price accuracy through their trading activities, face reduced opportunities. This shift leads to less information being collected about individual stocks, resulting in changes in trading dynamics, including increased trading activity and higher volatility for stocks that become more heavily indexed. Despite a decline in information production related to specific stocks, overall price informativeness remains unchanged, suggesting an intricate relationship between active and passive investing in preserving market efficiency.

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!
