US Market Hours Guide: What Time Does the US Market Open in Spain and Other Countries?

Overview of the US Stock Markets

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.

What Time Does the American Market Open in Spain and Other Spanish-Speaking Territories?

For Spanish and Latin American investors, understanding the time conversion is essential. Below are the opening and closing times in major cities:

Location Regular Session Opening Regular Session Closing
Madrid (Spain) 3:30 pm 10:00 pm
Caracas (Venezuela) 8:30 am 3:30 pm
Lima (Peru) 8:00 am 3:00 pm

Quito (Ecuador) 8:00 am 3:00 pm
Montevideo (Uruguay) 8:30 am 3:30 pm

For Spanish investors: The American market opens at 3:30 pm peninsular time, allowing for monitoring during the Spanish afternoon-evening. The pre-market session starts quite early (1:30 pm on NYSE and Nasdaq; 10:00 am on NYSE American).

2025 Holiday Calendar

The three markets are closed on the following days in 2025:

  • January 1: New Year’s Day
  • January 20: Martin Luther King Jr. Day
  • February 17: Washington’s Birthday
  • April 18: Good Friday
  • May 26: Memorial Day
  • June 19: Juneteenth National Independence Day (NYSE and Nasdaq)
  • July 4: Independence Day
  • September 1: Labor Day
  • November 27: Thanksgiving Day
  • December 25: Christmas Day

Note: Nasdaq does not observe Juneteenth, as it is a more recent holiday without an extended tradition.

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.
