The United States has three major stock markets operating under the same basic hours but with different characteristics. These are the New York Stock Exchange (NYSE), Nasdaq, and NYSE American. All operate in the Eastern Time (ET) zone and follow nearly identical trading calendars, allowing investors to move between them without difficulty.
Common Trading Hours Structure: Pre-Market, Regular Session, and After-Market
The three US markets operate under a three-phase daily structure:
Pre-Market Session: 4:00 am - 9:30 am (ET) on NYSE and Nasdaq; 7:00 am - 9:30 am (ET) on NYSE American
Regular Trading Session: 9:30 am - 4:00 pm (ET) on all markets
After-Market Session: 4:00 pm - 8:00 pm (ET) on all markets
These hours remain constant Monday through Friday, with markets closed on weekends.
The New York Stock Exchange (NYSE): The Main Market
The New York Stock Exchange represents the largest and most prestigious stock market in the world, historically known as Wall Street. The largest companies compete to be listed here, attracted by the participation of institutional investors.
Opening at 9:30 am local time and closing at 4:00 pm, the NYSE operates within an amplified trading context that includes pre-market movements from 4:00 am and post-market activity until 8:00 pm.
The NYSE’s uniqueness lies in hosting both large-cap companies and financial securities, making it a key reference point in the global stock market.
Nasdaq: The Technology Market
Nasdaq, an acronym for National Association of Securities Dealers Automated Quotation, operates with the same hours as the NYSE: opening at 9:30 am and closing at 4:00 pm (ET).
This market is notable for its concentration of technology and biotechnology companies, although its portfolio also includes firms from various sectors such as hospitality and air transportation. Unlike the NYSE, Nasdaq does not include financial securities in its composition.
The main Nasdaq indices are the Nasdaq 100 (comprising the 100 largest companies) and the Nasdaq Composite (encompassing all market-listed companies). These assets are reviewed annually in October, with changes implemented in December.
NYSE American (AMEX): Opportunities in Small Caps
NYSE American hosts small-cap companies (small caps) with high potential for appreciation, though characterized by lower liquidity and higher volatility. It is the space where future large companies emerge.
Its regular trading hours are identical (9:30 am - 4:00 pm ET), although its pre-market begins later: 7:00 am instead of 4:00 am.

2025 Holiday Calendar

May 26: Memorial Day

July 4: Independence Day
September 1: Labor Day
November 27: Thanksgiving Day
December 25: Christmas Day

Practical Considerations for International Traders
The pre-market and after-market structures significantly extend trading windows, enabling reactions to news and global events outside regular hours. Spanish investors should consider that the opening time of the American market in Spain coincides with their working afternoon, facilitating real-time monitoring.
The three trading sessions coexist within the same schedule, allowing diversification based on company type and risk preference, regardless of the investor’s local time zone.
