Institutional Investors' Different World
Institutional investors — mutual funds, pension funds, hedge funds, endowments — trade in large sizes and do not use retail discount brokers. They use institutional brokers, algorithms, and direct exchange access. They are not subject to PFOF-driven routing. Their execution challenges are different — primarily related to market impact and information leakage in large orders — not PFOF.
Small Retail Investor Exposure
Small retail investors — trading in hundreds or thousands of shares at a time through mobile apps — are exclusively affected by the retail brokerage ecosystem. Their orders are routed through PFOF arrangements. They have no negotiating power over execution quality or PFOF arrangements. The invisible cost of PFOF falls almost entirely on this population.
The Regulatory Implication
The asymmetric impact of PFOF means that the most powerful voices in financial regulation — institutional investors, hedge funds, financial industry firms — are largely unaffected by the practices that most harm small retail investors. This creates a political economy where the most-affected interests are least represented in regulatory deliberations, while the least-affected interests have the most resources to influence policy.
Building Retail Investor Political Power
Addressing the asymmetric impact of PFOF requires building retail investor political power sufficient to match the financial industry's regulatory influence. Organizations like Better Markets, the Consumer Federation of America, and retail investor advocacy groups work on this challenge. Individual investors who contact their representatives and regulators contribute to this effort.
