Trading Around the Clock: Inside FINRA's Trade Reporting Enhancements

Why It Matters

Longer reporting windows and accurate fractional‑share data improve market integrity, giving investors and regulators clearer, real‑time insight into trading activity.

Key Takeaways

• Reporting now starts at 4 a.m. ET
• Goal: 23‑hour, 5‑day trading by Dec 2026
• Fractional share trades now reported accurately
• Phantom volume distortion eliminated
• Enhanced data aids compliance and market oversight

Pulse Analysis

The Trade Reporting Facility (TRF) is the backbone of U.S. equity market transparency, aggregating trade data from exchanges and over‑the‑counter venues in milliseconds. By pushing the reporting start time to 4 a.m. ET, FINRA shortens the lag between pre‑market activity and official data dissemination, allowing market participants to react to overnight news with more reliable information. This adjustment also eases the operational strain of a future near‑continuous market, where data latency can be a competitive differentiator.

Preparing for a 23‑hour, five‑day trading regime by the end of 2026 reflects broader industry trends toward extended-hours liquidity. Brokers, clearing firms, and technology vendors must upgrade infrastructure to handle higher data volumes and ensure compliance across a broader window. The shift promises tighter price discovery and reduced arbitrage gaps between regular and after‑hours sessions, but it also raises questions about market surveillance, staffing, and the resilience of legacy systems under near‑continuous load.

FINRA’s new fractional‑share reporting requirement tackles the “phantom volume” issue that inflated perceived activity without corresponding economic substance. By mandating that each fractional transaction be captured in the TRF, the regulator delivers a more accurate picture of true market participation, benefiting retail investors who increasingly trade in sub‑share sizes. This granular visibility supports better risk assessment, enhances algorithmic trading models, and reinforces investor confidence as the market moves toward greater inclusivity and speed.

Original Description

Every time you check a stock price on your phone or watch a ticker scroll across a screen, you are seeing the result of a complex reporting system most investors never think about. Behind that number is a vast infrastructure capturing and consolidating trades from exchanges and over-the-counter markets in milliseconds—and that system is undergoing major enhancements.

On this episode, Chris Stone, FINRA Vice President, Transparency Services, takes us inside the systems that make market transparency possible. Stone explains how FINRA recently extended trade reporting hours to 4 a.m. ET, why the industry is preparing for 23-hour, 5-day-a-week trading by December 2026, and how FINRA’s recently implemented fractional share reporting is eliminating what researchers called "phantom volume."
