Fairness and the SEC’s Competing Regulatory Paradigms

Key Takeaways

• SEC’s fairness claims lack empirical support.
• Alternative Uptick Rule targets 10% daily price drops.
• Two fairness concepts: efficiency vs. public values.
• Short selling can improve price accuracy and liquidity.
• Separate qualitative fairness analysis could aid judicial defense.

Summary

The SEC’s recent rulemaking has come under heightened scrutiny for relying on fairness arguments without solid empirical evidence, especially in its cost‑benefit analyses. Critics focus on the Alternative Uptick Rule, a short‑selling restriction triggered by a 10% daily price drop, which the agency justified on perceived market fairness. Giovanni Patti’s new paper distinguishes two fairness paradigms—efficiency‑driven perceived fairness and an independent public‑values approach—and argues the SEC must clarify which it invokes. He proposes a structured framework and a separate qualitative fairness analysis to strengthen future regulations.

Pulse Analysis

The Securities and Exchange Commission operates under the Administrative Procedure Act, which demands that each rule be backed by a reasoned analysis. In recent years, the agency has leaned on fairness—protecting ordinary investors from sophisticated counterparts—as a cornerstone of its cost‑benefit calculations. Yet scholars and courts have repeatedly noted a gap between these fairness claims and the data needed to substantiate them, raising questions about the robustness of the SEC’s regulatory rationale.

Short‑selling regulation exemplifies this tension. The Alternative Uptick Rule, enacted after the 2008 crisis, halts short sales when a stock falls 10% in a single day, ostensibly to preserve market confidence. While the SEC argues the rule promotes perceived fairness, academic research shows short selling often enhances price discovery and liquidity. Without concrete evidence linking the rule to improved investor perception, the fairness justification remains speculative, blurring the line between efficiency‑driven and public‑values‑driven regulatory paradigms.

Patti’s article offers a pragmatic path forward. By distinguishing fairness as a determinant of market efficiency from fairness as an independent regulatory principle, the SEC can choose a clear analytical lens for each rule. A separate qualitative section dedicated to fairness considerations would prevent conflating efficiency metrics with normative goals, making the agency’s rationale more transparent and defensible. This bifurcated approach could satisfy judicial scrutiny, bolster investor trust, and ultimately lead to more balanced market regulations.
