Nasdaq 23-hour trading from December 6: overnight session falls in Indian daytime

The Nasdaq Stock Market plans to start trading 23 hours a day, five days a week, from Sunday, 6 December 2026, by adding an overnight session from 9 pm to 4 am US Eastern Time. With its existing pre-market, regular and after-hours sessions, trading would run continuously from Sunday evening to Friday evening, with a one-hour pause each day from 8 pm to 9 pm Eastern Time. In India the overnight session will fall from about 7:30 am to 2:30 pm IST, during the Indian trading day. The launch still depends on the readiness of the system that distributes market prices and on remaining regulatory approvals, the exchange says.

US shares have traded mainly in a fixed daytime window, with smaller pre-market and after-hours sessions around it. Investors in Asia, including India, have had to trade US shares either late at night their time or through limited extended-hours sessions. A near round-the-clock market means news that breaks outside New York hours, such as company results in Asia or a policy decision in Europe, can be reflected in prices as it happens.

For investors outside the United States, the longer day offers trading at more convenient local times. At the same time, overnight sessions usually have fewer buyers and sellers than the regular day, which can mean wider gaps between buying and selling prices and sharper price moves. Companies listed on Nasdaq also have to plan for news they release being traded on at any hour.

For Indian investors who own US shares through overseas investment platforms under the Liberalised Remittance Scheme, the overnight session will overlap with the Indian market day. Whether they can use it will depend on whether their broker offers access and on what terms. Nothing in the new hours changes tax or remittance rules.

Peepals calculation: In December, US Eastern Time is five hours behind UTC and India is five and a half hours ahead, so India is 10 hours 30 minutes ahead of New York. The overnight session of 9 pm to 4 am ET therefore runs from 7:30 am to 2:30 pm IST the next day, and the daily pause of 8 pm to 9 pm ET falls at 6:30 am to 7:30 am IST. The trading week, from Sunday 9 pm ET to Friday 8 pm ET, runs in India from Monday 7:30 am to Saturday 6:30 am. With India's main stock market session running from 9:15 am to 3:30 pm IST, the overlap with Nasdaq's overnight session would be about 5 hours 15 minutes (9:15 am to 2:30 pm). Our calculation from the reported figures.

Short-term: Brokers have to decide whether to offer the overnight session to customers and which shares they will allow. The 6 December launch also depends on the price-distribution system being ready.

Long-term: If overnight trading takes off, a growing share of US trading could happen during Asian hours, and prices of US-listed shares could react to global news faster. Thin overnight trading may also bring more volatile price moves in those hours.

Who is affected: Traders and investors in India and Asia who buy US shares, brokers and trading apps, companies listed on Nasdaq and NYSE Arca, and market-data providers.

What to watch next: Nasdaq's planned launch on Sunday, 6 December 2026, and any remaining approvals from the US Securities and Exchange Commission before then.
