Where to check today's stock market movement
The fastest way to see what happened to the stock market today is to visit a financial website that updates in real time. Yahoo Finance, Google Finance, MarketWatch, and CNBC all show the major indexes — the S&P 500, Dow Jones Industrial Average, and Nasdaq — with their gains or losses for the day, usually updated every few seconds during market hours.
If you have a brokerage account (through Fidelity, Charles Schwab, E*TRADE, or another firm), you can log in and see the same information on your account dashboard. Your bank's website may also display a market summary if you use their investment services. Most of these sites show the index value, the dollar change, and the percentage change since the previous market close.
The stock market closes at 4 p.m. Eastern time on weekdays. If you check after that time, you are looking at the final numbers for the day. If you check during the day, the numbers are live and will change as trading continues.
Key Takeaways
- The S&P 500, Dow Jones, and Nasdaq are the three main indexes that show overall market movement, and all three are free to check on financial websites.
- A positive percentage means the index went up; a negative percentage means it went down — the dollar amount shows how much the change was worth.
- Market hours are 9:30 a.m. to 4 p.m. Eastern time on weekdays, and numbers update in real time during those hours on most financial sites.
- After-hours trading happens from 4 p.m. to 8 p.m. Eastern time, but volume is much lower and prices can swing more dramatically than during regular hours.
Understanding the three main indexes
The S&P 500 tracks 500 large U.S. companies and is the most widely used measure of overall market health. When people say "the market is up" or "the market is down," they usually mean the S&P 500. It includes companies from many industries — technology, healthcare, finance, energy, and others.
The Dow Jones Industrial Average tracks 30 of the largest U.S. companies. It moves in the same general direction as the S&P 500 most days, but because it includes fewer companies, a big move in one stock can have a larger effect on the Dow's percentage change.
The Nasdaq Composite includes more than 3,000 stocks, but it is weighted heavily toward technology companies. On days when tech stocks move sharply, the Nasdaq often rises or falls more than the S&P 500 or Dow.
All three indexes are free to check, and seeing all three gives you a fuller picture than looking at just one. If the S&P 500 is up but the Nasdaq is down, it tells you that large tech stocks fell while other sectors held steady or gained.
What the numbers mean
When you see an index listed as "up 150 points" or "down 2.3%," the points are the dollar value and the percentage is the change relative to the previous day's close. A 2% gain means the index is worth 2% more than it was at the close of the previous trading day. A 2% loss means it is worth 2% less.
The percentage change is more useful than the point change when you are comparing different indexes or different time periods. A 150-point gain on the Dow is a different magnitude than a 150-point gain on the S&P 500 because the indexes have different base values.
You will also see individual stock prices listed as up or down. A stock listed as "+$3.50" or "+5.2%" has risen by that amount or percentage since the previous close. A "-$2.00" or "-3.1%" has fallen.
Why the market moved the way it did
Financial news sites publish articles throughout the day explaining what drove market movement. These explanations often point to economic data (jobs reports, inflation numbers, interest rate decisions), company earnings announcements, geopolitical events, or shifts in investor sentiment.
No single cause usually explains a day's movement. A market decline might be attributed to a disappointing jobs report, but it could also reflect investors selling stocks to lock in profits, or concern about a particular industry or company. Market commentary is often written after the fact and reflects what analysts think happened, not a definitive cause.
If you want to understand the reasoning behind a particular day's movement, read the market summary or analysis on MarketWatch, CNBC, or your brokerage's news section. These summaries are usually published by late afternoon and explain the main factors analysts point to.
Checking individual stocks you own or follow
If you own shares or follow specific companies, you can search for them by ticker symbol on any financial website. Type the symbol (AAPL for Apple, MSFT for Microsoft, TSLA for Tesla) into the search box, and you will see that stock's price, the change for the day, and a chart showing its movement over time.
Most sites also show the stock's opening price for the day, its high and low, and the volume of shares traded. Volume tells you how many shares changed hands — higher volume usually means more investor interest or conviction behind the move.
If you have a brokerage account, you can set up alerts to notify you when a stock you own rises or falls by a certain amount or percentage. This saves you from checking constantly throughout the day.
After-hours trading and overnight moves
After the regular market closes at 4 p.m. Eastern time, trading continues on electronic networks until 8 p.m. This is called after-hours trading. Volume is much lower, and prices can move more sharply because fewer buyers and sellers are active.
If a company releases earnings or major news after 4 p.m., the stock price may move significantly in after-hours trading. When the market opens the next morning, the stock may open at a different price than it closed the previous day, sometimes with a gap up or down.
Most individual investors cannot trade during after-hours sessions — your brokerage has to offer that feature, and it usually requires a higher account balance or a specific account type. If you see a stock has moved sharply overnight, it likely happened in after-hours trading or in response to overnight news.
International markets and futures
If you check market news early in the morning before the U.S. market opens, you may see references to European or Asian markets. These markets operate on their own schedules — European markets close before the U.S. opens, and Asian markets operate overnight U.S. time.
You will also see references to futures, which are contracts that bet on where an index will be at a future time. S&P 500 futures, Dow futures, and Nasdaq futures trade nearly 24 hours a day and give traders a way to position themselves before the regular market opens. Futures often move based on overnight news or economic data released before the U.S. market opens.
Futures prices are not the same as the actual index price, but they often signal whether the market is likely to open higher or lower. If S&P 500 futures are up 1% before the market opens, it suggests the S&P 500 will likely open higher, though the actual open may differ.
Frequently Asked Questions
Why did the market go down today when the news seemed good?
Markets react to many factors at once, and sometimes good news is already reflected in prices before it is announced. Investors may also sell stocks to lock in profits after a long rally, or they may be concerned about something else entirely — interest rates, a particular industry, or geopolitical risk. Market movement is rarely driven by a single cause.
Is the market open on weekends or holidays?
No. The U.S. stock market is closed on weekends and on federal holidays like Thanksgiving, Christmas, and Independence Day. On these days, you cannot trade, and the indexes do not update. Futures and international markets may trade, but the main U.S. indexes are closed.
Can I see what the market did before I woke up?
Yes. Financial websites keep a record of each day's opening, high, low, and closing prices. You can check any time and see what happened during the trading day, even if you check after the market closes. If you want to know what happened overnight in futures or international markets, search for "S&P 500 futures" or "Asian markets" on a financial news site.
What does it mean if the market is "flat" or "mixed"?
Flat means the index closed very close to where it opened — little to no change for the day. Mixed means some indexes went up while others went down, or some stocks gained while others fell. These terms describe days when there is no clear direction to market movement.
Do I need to check the market every day?
No. If you own stocks or funds in a long-term account, daily movement is normal and checking constantly can lead to emotional decisions. Most investors benefit from checking their portfolio monthly or quarterly rather than daily. If you are a day trader or actively manage your holdings, you may need to check more often.
