What time does the stock market stop trading

As a clear, beginner-friendly reference, this article answers the core search intent: what time does the stock market stop trading for major US exchanges (primarily the NYSE and Nasdaq), explains extended-hours sessions, holidays, halts and how brokers handle orders outside regular hours, and contrasts equities with 24/7 crypto markets. The simple short answer: the standard US equity regular session ends at 4:00 p.m. Eastern Time on normal trading days — but there are important caveats around pre-market and after-hours trading, auctions, holiday schedules, and emergency halts.

Note: As of 2026-01-16, according to Yahoo Finance reporting, US equities have shown renewed strength amid AI-related optimism and improved bank earnings, illustrating why understanding market hours and session mechanics matters for reacting to news events.

Regular (core) trading hours — United States

The primary, or "regular" trading session for US-listed equities runs Monday through Friday from 9:30 a.m. to 4:00 p.m. Eastern Time (ET).

These hours apply to the New York Stock Exchange (NYSE) and Nasdaq-listed securities for the main continuous trading session.
When people ask "what time does the stock market stop trading," they most often mean the end of this regular session: 4:00 p.m. ET.
Trades executed during 9:30 a.m.–4:00 p.m. ET are considered regular-hours trades and are used for official end-of-day pricing, index calculations, and standard settlement timing (T+2 for most equities at present unless otherwise specified by regulators or market rules).

Time zone equivalents

Common conversions for the 9:30 a.m.–4:00 p.m. ET window:

Central Time (CT): 8:30 a.m. – 3:00 p.m.
Mountain Time (MT): 7:30 a.m. – 2:00 p.m.
Pacific Time (PT): 6:30 a.m. – 1:00 p.m.

Eastern Time is used as the reference because the major US exchanges and the financial industry are centered in the Eastern Time zone (New York). That convention simplifies scheduling for national markets and global participants.

Extended-hours trading (pre-market and after-hours)

Extended-hours trading covers trading activity outside the 9:30 a.m.–4:00 p.m. ET regular session. These sessions allow orders to execute before the market opens and after it closes, but availability and specific rules depend on exchanges, alternative trading systems and broker platforms.

Typical extended-hours windows

Representative extended-hours ranges used by many brokers and venues (note: exact availability varies by platform):

Pre-market: as early as 4:00 a.m. ET on many retail platforms; some exchange pre-open processes and quote dissemination begin earlier for order entry and auction balancing.
After-hours: commonly until 8:00 p.m. ET on many venues and broker networks, though some venues close earlier (e.g., 6:00 p.m. ET) and some allow selective matched trading or dark-pool activity later.

Because what time does the stock market stop trading can refer to regular or extended sessions, remember the official stop for the core market is 4:00 p.m. ET — but trading can continue in after-hours windows on supported platforms.

Rules, order types and risks in extended hours

Extended-hours trading differs materially from the regular session:

Order types: Many brokers limit available order types to limit orders during pre-market and after-hours trading; market orders are often disallowed or strongly discouraged because they may execute at unpredictable prices.
Liquidity and spreads: Liquidity is generally lower outside regular hours. Wider bid-ask spreads are common, increasing execution cost and slippage risk.
Volatility and news sensitivity: Prices can move sharply on overnight or after-hours news (earnings, guidance, macro headlines), producing outsized moves on thin liquidity.
Execution risk: Partial fills, delayed confirmations and order cancellations are more frequent in extended hours.

Given these risks, many traders and investors prefer using limit orders and smaller sizes when trading outside core hours.

Exchange-specific schedules and sessions

Different US trading venues run slightly different session mechanics and market-access rules. The primary features to understand:

NYSE: Core continuous trading is 9:30 a.m.–4:00 p.m. ET with a formal pre-opening period (order imbalances and opening auction) and a distinct closing auction process. The NYSE operates multiple matching mechanisms and auctions that determine the official open and close prints.
Nasdaq: Also operates a 9:30 a.m.–4:00 p.m. ET continuous session and has its own pre-market and post-market procedures, including opening/closing cross auctions and imbalance handling.
Other venues: Electronic matching venues and ARCA-style platforms may run early sessions, quotes, and specific auction periods.

Order routing and execution quality can vary across venues even during regular hours; exchange-specific rules influence where an order ultimately matches.

Closing auction and imbalance periods

A critical reason many market participants focus on "what time does the stock market stop trading" is the importance of the closing auction.

Closing auction: Exchanges run a closing auction that aggregates buy and sell interest before 4:00 p.m. ET to determine a single official closing price (the close or "end-of-day print").
Imbalance period: In the minutes before the close (typically in the final minute or few minutes), exchanges publish order imbalance information that can cause rapid price movement as participants submit closing interest.
Why it matters: The official close is used for index reconstitution, fund NAVs, time-stamped price references, and many settlement-related processes. Large institutional activity often targets the closing auction to minimize market impact.

Market holidays and early-closing days

US exchanges observe an annual calendar of market holidays and may schedule early closes around major US holidays.

Typical holidays observed include New Year’s Day, Martin Luther King Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving and Christmas (exact dates shift yearly).
Early closes: Exchanges commonly schedule early closings (often 1:00 p.m. ET) on days such as the day after Thanksgiving and sometimes the trading day before Independence Day or Christmas Eve when it falls on a weekday.

Because holiday and early-close dates shift each year, check official exchange calendars for the current-year schedule rather than relying on past patterns.

How holiday/early-close schedules are published

Exchanges publish authoritative calendars and notices via their trading hours and holiday pages. Brokers also post internal cutoffs for order routing and settlement tied to exchange schedules. When planning trades around holidays, consult the exchange calendar and your broker’s notices for exact cutoffs.

Trading halts, circuit breakers and emergency closures

Scheduled hours can be interrupted by market control mechanisms:

Trading halts: Symbol-specific halts pause trading in a particular stock to allow dissemination of material news or to correct order imbalances.
Market-wide circuit breakers: Exchanges and regulators use price-based thresholds tied to major indices to temporarily pause market trading if the market drops by defined percentages in a single day. These pauses can occur during any trading session and may delay or alter the scheduled close.
Emergency closures: In rare cases (e.g., system outages or extreme events), exchanges may suspend trading or close early.

These mechanisms mean that even though the regular session typically stops at 4:00 p.m. ET, trading can be paused or delayed for regulatory or operational reasons.

How brokers and trading platforms handle orders when markets are closed

Broker practices vary, but common behaviors include:

Order acceptance vs execution: Many brokers accept orders 24/7 via their apps/websites, but orders are either queued for the next eligible session (pre-market or regular open) or routed to extended-hours venues if the broker supports after-hours execution.
Market vs limit: Market orders placed outside the regular session are often converted to limit orders or placed to execute only during regular hours to avoid unpredictable fills. Some brokers block market orders outside core hours.
Extended-hours access: Some brokers explicitly allow trading in pre-market and after-hours windows (with stated cutoffs such as 8:00 p.m. ET), while others only accept orders for the next regular session. Check broker documentation for exact availability.

Practical examples and cutoffs

Representative broker behaviors (examples for illustration; verify with your broker):

Many major brokers provide pre-market quoting and trading from around 4:00 a.m. ET and after-hours trading to around 8:00 p.m. ET for eligible securities and order types.
Brokers will also publish holiday and early-close cutoffs, such as the last time for same-day order submission for settlement on a particular date.

For active traders, understanding broker-specific extended-hours rules and cutoffs is essential to control execution risk.

Differences from cryptocurrency markets

Cryptocurrency exchanges operate 24/7 without formal opening or closing times. Key contrasts:

Continuous trading: Crypto markets trade every hour, every day. Equities have set trading windows with holidays and official auctions.
Price discovery and news reaction: Crypto prices can move at any hour, while equities often react first in pre-market or after-hours sessions and then during the regular session.
Safeguards: Equities have circuit breakers, regulated auction mechanisms and disclosure-driven halts. Crypto markets generally lack standardized circuit breakers across venues, though some platforms implement limits.

These structural differences mean investors need different operational practices: monitoring news around the clock in crypto, but focusing on session timing for equities.

Practical implications for investors and traders

Knowing what time does the stock market stop trading affects execution strategy and risk management:

Liquidity near close and in extended hours: Expect higher concentration and sometimes higher volatility near the 4:00 p.m. ET close and wider spreads outside regular hours.
Use of limit orders: Limit orders reduce the risk of unexpected fills when trading in pre- or after-hours sessions.
Earnings and news timing: Companies often release earnings before the open or after the close; trades reacting to these events may trade in pre-market or after-hours sessions with thin liquidity and wide spreads.
Portfolio marking and index rebalancing: Many funds use the official close price for valuation and rebalancing, so end-of-day prints can affect NAVs and index weights.

Operational tips:

If you need reliable fills at predictable prices, prioritize trading during 9:30 a.m.–4:00 p.m. ET.
If you trade in extended hours, choose limit orders and smaller sizes, and confirm your broker’s extended-hours execution policies.
Follow exchange calendars to avoid unexpected settlement or routing issues around holidays and early closes.
