Nasdaq has filed a proposal with the U.S. SEC to extend trading to nearly 24 hours a day, five days a week. If approved, it would create a 23-hour trading window (with a short daily break). This is not live yet.
Proposed timing
- Day session: 4:00 AM to 8:00 PM ET (2:30 PM to 6:30 AM IST)
- 1-hour break: system checks and end-of-day processing
- Overnight session: 9:00 PM to 4:00 AM ET (7:30 AM to 2:30 PM IST)
- Trades before midnight would count as part of the next trading day

What this could mean for India
- Faster global cues: U.S. news may get priced in sooner, instead of waiting for the next morning.
- Bigger short-term swings: IT, pharma, and commodity-linked stocks may react more sharply around the Indian market open.
- Short-lived pricing gaps: For Indian companies with U.S. ADRs, price differences between the U.S. and India listing may show up more often, but acting on them is usually difficult for most investors because of costs and rules.
- Long-term drivers stay local: India’s market direction still depends mainly on domestic growth, policy, and earnings.
SEBI context
Nasdaq is regulated by the U.S. SEC. SEBI regulates Indian exchanges separately, and any change to Indian market timings would require SEBI approval.
