Nasdaq Proposes Extended Trading Hours to Enhance Global Access

Nasdaq Inc., the second-largest stock exchange in the United States, has submitted a proposal to the Securities and Exchange Commission (SEC) seeking approval to extend its trading hours to 23 hours a day, five days a week. This initiative aims to accommodate growing global demand for U.S. equities, particularly from international investors whose local business hours do not align with traditional U.S. market hours. The proposed trading schedule includes a daytime session from 4:00 a.m. to 8:00 p.m. ET, followed by a new overnight "Night Session" from 9:00 p.m. to 4:00 a.m. ET.

The push for extended trading hours reflects a broader trend in the financial markets, where exchanges are increasingly adapting to the needs of global investors. Nasdaq's senior vice president, Chuck Mack, stated, “This evolution reflects a simple reality: global investors expect access on their terms, in their time zones, without compromising trust or market integrity.” Other exchanges, including the New York Stock Exchange, are also exploring similar expansions, with the NYSE planning to offer trading for 22 hours on weekdays.

Supporters of the extended hours argue that this change would enhance liquidity and allow investors to react to market-moving events in real time. Kerry Craig, a global market strategist at JPMorgan Asset Management, noted that the development could appeal to more retail investors worldwide. The ability to trade U.S. stocks outside traditional hours could also help investors manage overnight risks more effectively.

Despite the potential benefits, the proposal has faced significant criticism. Analysts from Wells Fargo described the plan as the “worst thing in the world,” expressing concerns that it could make stock trading resemble gambling due to increased volatility and thinner liquidity during off-peak hours. Critics argue that the majority of trading activity still occurs around the opening and closing bells, and extending hours could lead to erratic price movements and operational challenges for trading desks and clearinghouses.

While proponents emphasize the need for greater access and flexibility, opponents warn that extended trading hours may compromise market stability. Hebe Chen, an analyst at Vantage Markets, highlighted that the real test will be whether institutional traders participate during these extended hours. If institutional participation does not increase, the extended hours may result in noisier, less efficient trading.

Nasdaq moves toward 23-hour trading

Nasdaq aims to implement the extended trading hours in the second half of 2026, pending SEC approval and necessary infrastructure upgrades, including enhancements to the Depository Trust & Clearing Corporation's clearing processes. As the industry moves toward a more global trading environment, the outcome of this proposal could significantly reshape how investors engage with U.S. markets.
