Are you looking to invest or keep track of your portfolio? One of the first questions that often comes to mind is, "Is the US stock market open today?" In 2020, understanding the market hours and trading days is crucial for investors. In this article, we'll dive into the details of the US stock market's operating hours, including exceptions, and how it affects your investments.
Stock Market Hours in 2020
The US stock market operates on a specific schedule, with trading sessions for the primary exchanges, such as the New York Stock Exchange (NYSE) and the NASDAQ. Here's a breakdown of the regular trading hours:
- Morning Session (NYSE and NASDAQ):
- Opening Bell: 9:30 AM Eastern Time (ET)
- Closing Bell: 4:00 PM ET
During these hours, traders can buy and sell stocks, and the market price fluctuates based on supply and demand. It's important to note that these hours may vary slightly for different exchanges and markets.
Extended Hours Trading

In addition to the regular trading hours, there are also extended hours trading sessions available. These sessions allow investors to trade outside the regular market hours:
Pre-Market Session (4:00 AM – 9:30 AM ET): This session begins before the opening bell and provides investors with the opportunity to trade before the market officially opens. It's often used to set the day's opening price for stocks.
After-Hours Session (4:00 PM – 8:00 PM ET): This session takes place after the market has closed. Investors can buy and sell stocks, but trading volume tends to be lower compared to regular hours.
Holiday Hours
The US stock market is closed on certain holidays, including New Year's Day, Martin Luther King Jr. Day, President's Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. During these times, investors cannot trade or access their accounts.
2020 Exceptions and Special Considerations
2020 was a year marked by significant global events, such as the COVID-19 pandemic. The stock market experienced several changes and exceptions, including:
