Getting started with the stock market
Thinking about investing in stocks? With thousands of publicly traded companies to choose from, it helps to have a way to compare them side by side. A market screener lets you scan stocks by metrics like market capitalization, price change, and trading volume, rather than researching each company one at a time.
Market capitalization gives a sense of a company's size and how established it is, while trading volume shows how actively a stock is bought and sold — which affects how easily you can trade it. Use the screener below to explore the market, then click through to any company's dedicated page for a closer look at its chart and key facts.
What makes the stock market different
Unlike crypto, stock markets operate on set trading hours tied to their local exchange — the NYSE and Nasdaq, for example, trade Monday through Friday, roughly 9:30am to 4:00pm Eastern Time, and are closed on weekends and major holidays. Prices can still move outside these hours in pre-market and after-hours sessions, though typically with lower volume and wider price swings.
Stock prices are also tied directly to a specific company's underlying business — quarterly earnings reports, management changes, and broader economic data such as interest rate decisions all factor into how a stock is priced, more directly than with many other asset classes.
How to read the screener table
Beyond price and percentage change, the screener includes company-specific columns. Market Cap reflects the total value of all outstanding shares — commonly used to categorize companies as large-cap, mid-cap, or small-cap. P/E (price-to-earnings ratio) compares a company's share price to its earnings per share, one commonly referenced way to gauge how a stock is priced relative to its profits — though it isn't conclusive on its own.
EPS (TTM) is earnings per share over the trailing twelve months, and Sector groups the company alongside others in a similar line of business. Together, these figures help you compare companies on a like-for-like basis rather than by price alone.
Main segments within stocks
Stocks are often grouped by sector — Technology, Healthcare, Financials, Energy, Consumer goods, and others — since companies in the same sector tend to be influenced by similar economic forces and industry trends.
They're also commonly split by size: large-cap companies (generally the most established, widely-held names) tend to be more closely followed by analysts, while small-cap companies can be newer or less widely covered, which sometimes means wider price swings on less trading volume.

More questions about reading the stock market
What's the difference between market cap and stock price?
Stock price is just the cost of one share; market cap is the price multiplied by the total number of shares outstanding. Two companies can have very similar share prices but vastly different market caps if they have different numbers of shares in circulation.
Why do two companies with similar stock prices have very different market caps?
It comes down to share count. A company with a $50 share price and 10 billion shares outstanding has a much larger market cap than one with the same $50 price but only 100 million shares — price alone doesn't reflect company size.
What does Technical Rating mean on the screener?
It's an automated summary of common technical indicators (like moving averages and oscillators) condensed into a single Buy/Sell/Neutral signal. It reflects price-pattern analysis only — not news, earnings, or company fundamentals.
