Regulators Consider 24/7 Trading. Here's What Investors Need to Know

The SEC and CFTC are spearheading a significant modernization of U.S. financial markets, collaborating to extend equity trading hours, potentially to 24/7, and foster the development of digital assets, including tokenized stocks. This regulatory push, aimed at harmonizing oversight and promoting innovation, offers increased market accessibility but also introduces substantial challenges such as reduced liquidity, wider bid-ask spreads, and heightened volatility during extended hours. The shift necessitates considerable operational adaptations for exchanges and presents strategic implications for institutional investors and brokerages navigating evolving market structures.

Analysis

A significant regulatory shift is underway as the SEC and CFTC collaborate to modernize U.S. financial markets, with a focus on extending equity trading hours—potentially to 24/7—and harmonizing oversight for digital assets. Major exchanges, including Nasdaq and the NYSE (owned by Intercontinental Exchange), are actively developing plans for near-continuous trading, while brokerages like Robinhood, Interactive Brokers, and Charles Schwab already offer some form of after-hours access. This evolution runs parallel to the development of tokenized stocks, which could trade continuously on blockchain platforms like Ethereum or Solana, further blurring the lines between traditional and crypto finance. While extended hours promise greater accessibility for retail and international investors—who currently hold 18% of U.S. equities—they also introduce material risks. Current out-of-hours trading, which accounts for approximately 11% of total volume, is characterized by lower liquidity, wider bid-ask spreads, and increased price volatility. The regulatory proposal to move this activity from alternative trading systems and dark pools to fully lit, regulated exchanges could mitigate some of these risks by improving transparency and liquidity, but significant operational and technical hurdles for exchanges remain.

Key Decisions for Investors

• Investors should evaluate positions in brokerage firms like Robinhood (HOOD), Interactive Brokers (IBKR), and Charles Schwab (SCHW), as their existing infrastructure for extended-hours trading and digital assets positions them to potentially benefit from these regulatory changes.
• Consider the operational and capital expenditure impacts on exchange operators such as Intercontinental Exchange (ICE) and Nasdaq (NDAQ) as they transition towards 24-hour trading models, weighing potential revenue growth against implementation costs.
• Traders engaging in extended-hours sessions must prepare for lower liquidity and higher volatility, which can lead to wider spreads and less favorable execution prices; it is critical to monitor the shift of these volumes to lit exchanges, which may improve market conditions over time.
• Watch for developments in smart-contract platforms like Ethereum (ETH) and Solana (SOL), as they are identified as the likely foundational infrastructure for the growth of tokenized securities, representing a new frontier for digital asset investment.
