Investors may soon have the chance to trade on the Nasdaq for nearly 23 hours a day as the exchange seeks regulatory approval for near-continuous trading. This initiative aims to address the rising global interest in U.S. equities, prompting exchanges to rethink traditional trading hours. Nasdaq, home to major tech firms such as Nvidia, Apple, and Amazon, has submitted a proposal to the U.S. Securities and Exchange Commission (SEC) that could significantly broaden trading hours, potentially allowing round-the-clock access for international investors.
Proposed Trading Schedule
With the new proposal, Nasdaq intends to extend its trading hours from the current 16 hours to 23 hours daily. The exchange currently operates a pre-market session from 4 a.m. to 9:30 a.m. Eastern Time, followed by a regular trading session from 9:30 a.m. to 4 p.m., and a post-market session until 8 p.m. The proposed structure streamlined into two extended sessions would include a continuous day session from 4 a.m. to 8 p.m., followed by a one-hour operational break. A night session would start at 9 p.m. and continue until 4 a.m. the next day, with trades executed between 9 p.m. and midnight recorded for the following day. The trading week would commence at 9 p.m. on Sunday and end at 8 p.m. on Friday, while the opening and closing bells would stay the same at 9:30 a.m. and 4 p.m.
Infrastructure and Market Impact
The transition to continuous trading depends on necessary infrastructure upgrades, particularly to the securities information processor that consolidates stock prices across U.S. exchanges. The U.S. Depository Trust and Clearing Corporation is also anticipated to implement nonstop stock clearing by the end of 2026. Supporters of extended trading hours argue that this change would allow investors outside the U.S. to respond more quickly to global events occurring when U.S. markets are closed. However, Wall Street banks have raised concerns regarding potential challenges like thinner liquidity, increased volatility, and the commercial feasibility of nonstop trading.
Chuck Mack, senior vice president of North American markets at Nasdaq, mentioned that demand for overnight trading has surged, although trading volumes during extended hours have historically been lower. Many investors currently turn to off-exchange platforms and alternative trading systems to access markets outside regular hours. Mack highlighted that global investors are eager to engage with the U.S. market on their own terms and timelines.
A Shift in Market Dynamics
The proposed changes illustrate a broader trend toward globalization in the U.S. markets, which now account for nearly two-thirds of the global listed market value. Nasdaq data indicates that overseas investors held $17 trillion worth of U.S. equities last year. This increasing international interest has compelled exchanges to adjust their trading models to cater to the needs of global investors.
Traditionally, U.S. exchange trading hours have seen little change over the past century, originating in an era when transactions took place in person on trading floors. Despite the current predominance of electronic trading, market schedules have evolved little over time. Earlier this year, Nasdaq also filed with regulators to allow trading in tokenized stocks, reflecting a growing interest in tokenization amid a relaxation of crypto-related regulations. As the trading landscape evolves, Nasdaq’s proposal for extended hours could signify a meaningful shift in how global investors engage with U.S. markets.
