Finance and Operations Research
Mike Green is widely recognized for his pioneering research on the systemic impacts of passive investing and indexation on global financial markets.
He has demonstrated how passive investment vehicles, which simply track index weights and react to fund flows, rely heavily on active managers and market makers for liquidity, governance, and true price discovery.
Green argues that as passive strategies grow in dominance, markets face heightened risks of sharp repricing, reduced corporate accountability, and structural distortions in valuation.
His research also examines broader macro effects, including muted day-to-day volatility, elevated cross-asset correlations, and long-term shifts in wealth concentration, solidifying his reputation as one of the most influential and frequently cited thinkers on passive-investing dynamics.
