You cannot find today's stock market performance on this site

Housing Info publishes guides about housing programs, not financial data. Stock market prices change every few seconds during trading hours, and any number we published would be outdated within minutes. You need a live source instead.

The major U.S. stock indexes — the S&P 500, Dow Jones Industrial Average, and Nasdaq Composite — are tracked in real time by financial websites and apps. Yahoo Finance, Google Finance, CNBC, MarketWatch, and your brokerage account (if you have one) all show current prices, percentage changes, and trading volume updated throughout the trading day.

If you arrived here looking for stock market information, you are on the wrong site. This guide explains where to look instead and what the common terms mean so you can understand what you are reading.

Key Takeaways

  • Stock market data updates constantly during trading hours and requires a live financial website or app, not a static guide.
  • The three major U.S. indexes are the S&P 500, Dow Jones Industrial Average, and Nasdaq Composite, and each tracks a different set of companies.
  • A percentage change tells you how much an index moved; a point change tells you the raw number of points but is less meaningful for comparison.
  • Market data is free on Yahoo Finance, Google Finance, CNBC, and most brokerage apps, and updates during market hours (9:30 a.m. to 4 p.m. Eastern, Monday through Friday).

Where to check stock market data right now

Open any of these sites or apps in a new tab to see live market data. All are free and require no account to view basic information.

Yahoo Finance (finance.yahoo.com) shows the three major indexes at the top of the home page with current price, change in points, and percentage change. You can click each index name to see which companies are included and how much each one moved.

Google Finance (google.com/finance) works the same way — type an index name or ticker symbol into the search box and you get the current price and a chart. CNBC (cnbc.com) and MarketWatch (marketwatch.com) both publish market news alongside live data and are aimed at people who follow stocks regularly.

If you own stocks or have a brokerage account, your account dashboard shows market data automatically. Fidelity, Charles Schwab, E*TRADE, and other brokerages update prices in real time for account holders.

What the three major indexes measure

The S&P 500 tracks 500 large U.S. companies across all industries. It is the most commonly used measure of overall U.S. stock market health because it is broad and includes familiar names like Apple, Microsoft, and Coca-Cola.

The Dow Jones Industrial Average (often called "the Dow") tracks only 30 large U.S. companies, all blue-chip stocks considered stable and established. It is older and narrower than the S&P 500, so it moves differently on any given day.

The Nasdaq Composite includes all stocks listed on the Nasdaq exchange, which has a higher concentration of technology companies. It tends to move more sharply than the S&P 500 because tech stocks are more volatile.

None of these indexes is "the stock market" — they are three different snapshots of it. On some days all three move in the same direction; on others they diverge. Checking all three gives you a fuller picture than looking at one alone.

Understanding percentage change versus point change

When you see market data, you will see two numbers: points and percentage. The percentage change is what matters for comparison. If the S&P 500 is up 1.5%, that tells you the index gained 1.5% of its total value. If it is up 50 points, that number alone does not tell you whether that is a big move or a small one — it depends on what the index was worth to begin with.

Think of it like a salary raise. A $5,000 raise means something different to someone earning $30,000 a year than to someone earning $150,000 a year. The percentage tells you the real story. The same is true for stock indexes.

Most financial websites show both numbers, but focus on the percentage when you are trying to understand whether the market had a big day or a small one.

Market hours and when data updates

The U.S. stock market is open Monday through Friday, 9:30 a.m. to 4 p.m. Eastern Time. Data updates continuously during those hours. Before 9:30 a.m. and after 4 p.m., the market is closed and prices do not change (though some brokerages allow trading in "after-hours" sessions with different rules and wider spreads).

On weekends and federal holidays, the market is closed and no trading happens. Any data you see on Saturday or Sunday is from the previous Friday's close.

If you check a financial website outside market hours, you will see the last price from when the market closed, not a live price. The site will usually label it as "closed" or show the time of the last update.

Why this site does not publish market data

Housing Info is a guide to housing programs and benefits. We do not publish financial data because it changes too fast and requires live updating. A number we published at 10 a.m. would be wrong by 10:05 a.m., and we cannot update fast enough to keep up.

Financial websites and apps are built specifically to handle this constant flow of data. They have the infrastructure to update prices in real time and the expertise to present it clearly. That is where you should go for market information.

If you have questions about how stock markets work or what the terms mean, this guide can help. If you need to know what the market is doing right now, use one of the live sources listed above.

Frequently Asked Questions

What time does the stock market open and close?

The U.S. stock market opens at 9:30 a.m. Eastern Time and closes at 4 p.m. Eastern Time, Monday through Friday. Some brokerages offer pre-market trading starting at 4 a.m. and after-hours trading until 8 p.m., but these sessions have lower volume and wider price spreads.

Is the market open on weekends?

No. The stock market is closed on weekends and federal holidays. If you check market data on Saturday or Sunday, you are seeing the closing price from Friday. Trading resumes Monday morning at 9:30 a.m. Eastern.

Why do the S&P 500, Dow, and Nasdaq move differently on the same day?

Each index tracks a different set of companies. The Nasdaq has more technology stocks, which can be more volatile. The Dow is only 30 companies, so a big move in one of them affects the index more. The S&P 500 is broader and more balanced, so it usually moves less sharply than the other two.

Can I see stock market data on my phone?

Yes. Yahoo Finance, Google Finance, and CNBC all have mobile apps and mobile websites. If you have a brokerage account, your broker's app will show market data. All update in real time during market hours.
