CME Globex futures trade nearly 24 hours a day

Trading for the week begins Sunday evening and concludes Friday afternoon, with short daily breaks throughout the period.

Pre-market and after-hours sessions offer extended trading windows

Eastern time on major exchanges like Nasdaq and NYSE Arca. Individual brokerage firms determine their own specific access hours for these sessions.

Most brokers limit activity during pre-market sessions to limit orders rather than market orders, and prices for the same stock may differ across various trading venues. Trading outside of regular hours typically results in wider bid-ask price gaps because there are a lower number of active buyers and sellers.

After-hours trading occurs between 4 p.m. Eastern and 8 p.m. Eastern on exchanges such as Nasdaq and NYSE Arca. Individual brokers set their own access hours, and some may require orders to be specifically marked for the extended session or conclude their windows before 8 p.m. Eastern.

Trading on Nasdaq and NYSE Arca pauses after the after-hours session and does not resume until the pre-market session begins the following morning.

Official prices are set during opening and closing auctions

Trading days begin with an opening auction to determine an official price at 9:30 a.m. Eastern time. Nasdaq refers to this process as the Opening Cross, while NYSE-listed stocks are managed by designated market makers. A stock may open at a different price level than where it traded just minutes before the session began.

At 4 p.m. Eastern, a closing auction establishes the official closing price for each stock. Nasdaq refers to its version of this process as the Closing Cross. This official closing price remains unchanged by any subsequent trades, and financial sites and broker applications display after-hours movements as a separate figure.

The next day’s percentage change for a stock is measured against this official 4 p.m. close rather than the last trade of the previous evening.

NYSE and Nasdaq utilize different trading structures

The Nasdaq functions entirely through electronic systems without a physical trading floor.

Daily ritual ceremonies differ between the two exchanges. The New York Stock Exchange holds opening and closing bell ceremonies at its physical location. The Nasdaq conducts its own ceremonies at its MarketSite studio located in Times Square.

Economic data and corporate earnings influence market movements

Eastern time. This release occurs one hour before the official opening of the regular market session.

Index providers and mutual funds calculate daily net asset values and end-of-day levels using the 4 p.m. Eastern closing prices. Benchmark indexes like the S&P 500 rely on regular session trades and do not incorporate after-hours price movements.

These releases are often followed by analyst conference calls where executive guidance can influence after-hours price action. Corporate announcements regarding mergers, leadership changes, and share sales typically occur after the market closes.
