Lead summary: What a stock exchange is and why it matters
A stock exchange is a marketplace that brings together buyers and sellers of company shares (equities). Exchanges enable price discovery — the process that determines the price of a share — and provide the infrastructure for trading, reporting, clearing, and settlement. For companies, exchanges provide access to capital through public listings; for investors, they provide liquidity (the ability to buy and sell) and a transparent venue for valuing ownership stakes.
Basic concepts and vocabulary
Beginners should know a handful of core terms before digging deeper:
- Stock / Share: A unit of ownership in a company. Owning a share usually entitles the holder to a portion of profits (dividends) and voting rights, depending on the share class.
- Equity: Collective ownership of a company represented by stocks.
- Shareholder: A person or institution that owns shares.
- Market capitalization: The total market value of a company’s outstanding shares (price × shares outstanding).
- Dividend: A distribution of earnings to shareholders, when declared by a company.
- Index: A basket of stocks used as a benchmark (examples explained later).
- Bid and Ask: The bid is the highest price a buyer is willing to pay; the ask is the lowest price a seller will accept.
- Bid–ask spread: The difference between the ask and the bid — a key measure of transaction cost and liquidity.
- Liquidity: How quickly an asset can be bought or sold without moving its price much.
- Volatility: The degree of price movement over time. Higher volatility means prices change more rapidly.
- Primary vs Secondary market: The primary market is where new shares are issued (IPOs); the secondary market is where investors trade existing shares.
History and evolution of stock exchanges
Stock exchanges evolved from informal merchant trading floors to regulated, electronic marketplaces. Historically, merchants and brokers met in coffee houses or trading floors to negotiate prices. Formal exchanges developed rules and listing standards to standardize trading. Over the past several decades, manual open-outcry trading on exchange floors has largely given way to electronic order books and automated matching engines, improving speed, transparency, and reach.
Types of markets and exchanges
At a high level, understand two market types:
- Primary market: Companies issue new shares to raise capital (initial public offerings, follow-on offerings). Underwriters and investment banks typically coordinate these events.
- Secondary market: Investors buy and sell existing shares among themselves; the company generally does not receive proceeds from these trades.
Exchanges can operate as auction markets (where buyers and sellers interact through an order book) or as dealer/quote-driven markets (where market makers post buy and sell quotes). Modern electronic venues include centralized exchanges and alternative trading systems that all together form the market ecosystem.
How trades are executed
Understanding trade execution helps beginners see the path from deciding to buy or sell to actually owning or disposing of shares.
Order placement
When you place an order through a broker or trading app, you choose an order type (market, limit, stop, etc.) and specify quantity. Your broker may route the order to an exchange, to a market maker, or to an alternative trading venue depending on routing logic and best execution rules.
Order routing and matching
Orders reach an exchange’s order book where matching occurs. An order book lists bids (buy orders) and asks (sell orders) by price and time priority. Market orders match immediately to the best available price; limit orders wait until the market reaches the specified price. Market makers and liquidity providers supply quotes and can execute against incoming orders to maintain orderly markets.
Execution and confirmation
When your order is matched, the trade is executed and you receive a confirmation showing trade price, quantity, fees, and timestamp. Execution price may differ slightly from the price you saw due to market movements and spread.
Settlement
After execution, post-trade processing begins. Clearinghouses calculate obligations and net positions among counterparties. Settlement is the exchange of cash for securities and commonly follows a T+2 cycle in U.S. equities (trade date plus two business days). Organizations like the Depository Trust & Clearing Corporation (DTCC) play central roles in U.S. clearing and settlement.
Order types and how they work
Beginners should know common order types and when to use each:
- Market order: Buy or sell immediately at the best available price. Use when speed is more important than price certainty, but be aware of slippage in fast markets.
- Limit order: Buy or sell at a specified price or better. Use to control execution price but be prepared that the order may not fill.
- Stop-loss order: An order that becomes a market order once the stop price is reached; often used to limit losses.
- Stop-limit order: Becomes a limit order at the specified stop price; offers price control but no guarantee of fill.
- Fill-or-kill (FOK): Execute the entire order immediately or cancel it. Useful for large orders where partial fills are not acceptable.
- Good-til-canceled (GTC) / Day orders: Specify how long a limit order should remain active.
Order matching and liquidity providers
Exchanges match buy and sell orders either directly in the central order book or via intermediaries. Liquidity providers — including designated market makers and electronic firms — continuously post bid and ask quotes to facilitate trading. Their presence narrows bid–ask spreads and improves market depth, making it easier to execute larger orders with less price impact.
Market participants
Key participants include:
- Retail investors: Individual investors using brokerage accounts to trade stocks and funds.
- Institutional investors: Mutual funds, pension funds, hedge funds, insurance companies — they trade large volumes and can move markets.
- Brokers: Intermediaries that accept client orders and route them to execution venues.
- Dealers / Market makers: Firms that provide continuous quotes and buy/sell for their own inventory.
- Exchange operators: Organizations that maintain trading infrastructure, enforce rules, and publish market data.
- Clearinghouses: Entities that stand between buyers and sellers to manage counterparty risk and handle settlement.
- Regulators: Agencies that enforce market rules, such as the U.S. Securities and Exchange Commission (SEC), to protect investors and ensure fair markets.
Clearing, settlement, and custody
Clearing and settlement are crucial safety and operational features of modern markets. Clearinghouses guarantee that the buyer receives shares and the seller receives cash, even if one party defaults. Netting reduces the number of transactions by offsetting buys and sells among participants. Settlement finality ensures assets and funds are irreversibly exchanged, and custody services hold securities on behalf of investors. In the U.S., the DTCC and its subsidiaries handle much of this post-trade work.
Market data, quotes, and transparency
Market data underpins price discovery. Level 1 data shows best bid and ask and last trade — enough for many retail investors. Level 2 provides the full order book view, revealing depth at multiple price levels. Exchanges publish trade and quote data through consolidated tapes and feed services. Transparency regulations aim to give investors access to timely information so they can make informed decisions.
Regulation and investor protection
Regulators like the SEC in the U.S. set rules that promote fair, orderly, and efficient markets. Key objectives are preventing fraud, requiring transparent disclosure from public companies, policing insider trading, and ensuring brokers deliver best execution. Investor protections also include rules on margin, short selling disclosures, and market circuit breakers to limit extreme volatility.
Market infrastructure and technology
Modern exchanges run on high-performance matching engines and electronic order books. Algorithmic trading and automated strategies contribute a large share of daily volume. Low latency (very fast execution) matters in competitive environments, while robust surveillance systems monitor for manipulation and unusual behavior. Technology has lowered transaction costs and broadened market access but also made markets more complex.
How companies get listed
Listing begins with meeting exchange-specific requirements for finances, corporate governance, and reporting. Companies work with underwriters on pricing and distributing shares during an IPO. After listing, companies must file regular financial reports and meet ongoing disclosure obligations so investors can assess performance.
How individuals invest through exchanges
To trade on an exchange, most individuals open a brokerage account with a regulated broker. You can choose full-service brokers, discount brokers, or online/mobile brokers depending on the services you need. Many modern platforms support fractional shares, ETFs (exchange-traded funds), and automated investing. For custody and wallet services related to broader digital asset activity, Bitget Wallet is a recommended option for secure custody and user-friendly controls.
Fees, costs, and tax considerations
Common trading costs include commissions (less common today), bid–ask spreads, exchange and regulatory fees, and clearing fees. Taxes depend on your jurisdiction — in the U.S., short-term capital gains (assets held less than a year) are usually taxed at higher ordinary-income rates, while long-term gains enjoy preferential rates. Dividends may also be taxed; keep records and consult tax resources to understand your liabilities.
Market behaviours and drivers of price
Stock prices move when supply and demand change. Drivers include company fundamentals (earnings, growth prospects), macroeconomic news (interest rates, employment), industry trends, and investor sentiment. Earnings reports and guidance often cause price reactions. Market indices provide snapshot views of market performance and sentiment.
Risks and how to manage them
Principal risks in stock markets include market risk (prices fall), liquidity risk (difficulty selling quickly), execution risk (orders fill at worse prices), and counterparty risk (failure in settlement). Beginners can manage risk by diversifying holdings, maintaining a suitable time horizon, avoiding excessive leverage, and using stop orders thoughtfully. Remember that diversification reduces but does not eliminate risk.
Differences between stock exchanges and cryptocurrency exchanges
Stock exchanges trade regulated securities and are subject to long-established oversight and listing standards. Cryptocurrency exchanges trade digital tokens, often operate 24/7, and use different custody and settlement models. Settlement finality differs: securities typically settle via centralized clearinghouses within a set cycle (e.g., T+2), while crypto transfers settle on blockchains (with different assurances). For beginners active in both markets, using trusted, regulated platforms like Bitget for crypto trading and custody simplifies compliance and safety.
Special topics
Dark pools and alternative trading systems
Dark pools are private venues where large orders can be executed away from public order books to reduce market impact. While useful for block trades, they reduce pre-trade transparency, which can affect price discovery. Regulators monitor the use of dark pools to ensure fairness.
Short selling and margin trading
Short selling involves borrowing shares to sell now and buy back later, hoping the price falls. Margin trading uses borrowed funds to amplify exposure. Both increase potential gains and losses; margin can lead to margin calls and forced liquidation if positions move against you. These strategies are advanced and carry significant risk.
Market indices and benchmarks
Indices like the S&P 500 and Dow Jones are benchmarks representing segments of the market. Investors use index funds and ETFs to gain diversified exposure without picking single stocks. Benchmarks help evaluate investment performance against a relevant market segment.

Frequently asked questions (FAQ)
When is the market open?
Regular U.S. equity market hours are typically weekdays, with a standard session running from 9:30 a.m. to 4:00 p.m. Eastern Time. There are also pre-market and after-hours sessions with lower liquidity.
What is the difference between a limit order and a market order?
A market order executes immediately at the best available price; a limit order executes only at a specified price or better. Market orders offer speed; limit orders offer price control.
How much money do I need to start?
You can begin with small amounts thanks to fractional shares and low-cost brokers, but be mindful of fees and diversification. Start with an amount you can afford to keep invested for a meaningful period.
Practical example: A simple trade lifecycle
1) You place a limit buy order for 10 shares at $20 each via your broker app. 2) The broker routes the order to an exchange order book. 3) A seller’s ask at $20 matches your limit and the trade executes. 4) You receive a trade confirmation. 5) Clearing nets obligations and settlement occurs on T+2, after which the shares are in your brokerage custody.
