The stock market has historically been a critical building block in the growth of household wealth and corporate funding. Stocks are bought and sold during specified hours on exchanges.
Many Americans are familiar with the major exchanges in the U.S.: the New York Stock Exchange, or NYSE, and the Nasdaq, which originally was an acronym for the National Association of Securities Dealers Automated Quotations. Here’s what you need to know about stock market hours, holidays and how the exchanges operate.
U.S. Stock Market Holidays in 2025
The NYSE and Nasdaq are open on New Year’s Eve, but will be closed on Wednesday, Jan. 1, in observance of New Year’s Day.

More about trading hours and market holidays:
In the U.S., most exchanges are open on weekdays from 9:30 a.m. to 4 p.m. Eastern time.
You can still trade shares on the stock market outside normal trading hours on a platform known as an electronic communication network, or ECN. The ECN matches buyers and sellers, and it takes a fee or commission for transactions. Such “after hours” trading happens between 4 p.m. and 8 p.m. Eastern time. You can also trade before the market opens during premarket trading from 4 a.m. to 9:30 a.m.
Extended-hours trading can benefit traders who find it more convenient for their schedules or who want to trade on news that might influence share values. However, extended-hours trading also comes with risk due to lower trade volumes, so traders can only use “limit” orders when trading after hours. Limit orders allow you to either transact securities at a predesignated price or not trade at all if your conditions aren’t met.
The stock market is open when regular trading can start on an exchange. Furthermore, the stock market has holidays, so if today is not on the list of stock market holidays, the stock market is open. The holidays on which different stock exchanges are closed vary, and overseas markets like the London Stock Exchange, or LSE, may have “bank holidays” that are not followed in the U.S.
Earnings reports can provide helpful information for investors about the financial health of a business. Reports often provide broad information by management on the drivers of company performance, risks, litigation and other important factors. They also provide financial statements, which can be helpful for investors who want to analyze the performance of a company and make projections for the future.
The simplest way to find earnings reports is to use the term “earnings calendar” in a search engine.
Stock exchanges facilitate transactions between traders. They host companies’ shares, which increases those companies’ access to public capital. In return, the companies must pay a listing fee and annual fees. Exchanges also bolster their top line with transaction fees, market data fees, software offerings and a slew of other fees. Notably, stocks can be listed on any number of exchanges as long as they qualify for listing on said exchanges.
Major stock exchanges overseas include the LSE, the Tokyo Stock Exchange and the Hong Kong Stock Exchange.
Stocks do not necessarily need to be traded on exchanges to be part of the stock market and can instead trade over-the-counter, or OTC, as is the case with pink sheet listings.
A form of security that is both listed on exchanges and OTC is American depositary receipts, or ADRs, which are available when U.S. banks purchase a foreign stock and then sell an ADR as a proxy for the foreign stock. ADRs are helpful for investors who want to gain access to foreign investments, which can provide portfolio diversification.
