How the Stock Market Works

Does the stock market work? This article answers that question clearly and practically. You will learn what the stock market is, who participates, how prices form, how trades clear and settle, common instruments, order types, risks, and how equities compare with cryptocurrency markets. The content is beginner-friendly and includes timely market context (news references noted by date and source) and practical guidance for accessing markets via brokerages and Bitget services.

Overview and Purpose

The stock market is a network of venues and systems where shares of publicly traded companies are issued, bought, and sold. At its core, the stock market enables three economic functions: raising capital for companies, providing liquidity for investors, and producing price signals that reflect supply, demand, and expectations.

Many readers ask, "does the stock market work" as a way to understand whether it reliably performs these functions. In practical terms, yes: through primary offerings, continuous secondary trading, and regulated infrastructure, equity markets allow capital flows from savers to businesses while offering mechanisms to manage risk and measure value. This article explains how that happens step by step.

Brief History

Stock markets originated in the early modern period. The Dutch East India Company (VOC) issued tradable shares in the 17th century, creating one of the first public equity markets. Over centuries, exchanges evolved from open-outcry trading floors to sophisticated electronic marketplaces powered by matching engines and automated order routing.

Key regulatory milestones shaped market integrity. For example, 20th-century securities laws introduced disclosure requirements, oversight of brokers and exchanges, and rules against market manipulation. Technological shifts—decimalization of prices, electronic trading, algorithmic strategies, and real-time data—further transformed speed, access, and complexity.

Market Structure

Primary Market

The primary market is where companies raise capital by issuing new shares to investors. Common methods include:

Initial Public Offerings (IPOs): A private company lists shares publicly, usually with underwriters helping price and allocate shares.
Direct listings: Companies list existing shares without issuing new ones; pricing is driven by market orders at listing.
Follow-on offerings: Public companies issue additional shares to raise more capital.

Underwriting, prospectuses, and regulatory filings provide transparency for investors in the primary market. Companies disclose financials, risks, and business strategies so investors can evaluate the offering.

Secondary Market

The secondary market is where existing shares change hands between investors after issuance. Trades occur on exchanges, alternative trading systems (ATS), and over-the-counter (OTC) venues. Secondary markets provide liquidity and continuous price discovery: they are where the question “does the stock market work” most directly plays out for everyday investors.

Exchanges and Trading Venues

Major exchanges operate matching engines that pair buy and sell orders. Examples of well-known national exchanges exist globally; when choosing a venue to trade, retail and institutional investors use regulated brokerages to access them. Modern venues include centralized order books, electronic communication networks (ECNs), and broker-dealers’ internalization systems.

Bitget offers robust market access for traders and investors who want transparent execution and custody options. For crypto-native investors or those bridging TradFi and digital assets, Bitget Wallet and Bitget’s trading products can serve as on-ramps to equities and tokenized real-world assets when available through regulated offerings.

Market Participants

Retail Investors

Retail investors are individuals who buy and sell shares through brokerage accounts, retirement plans, and investment apps. Their role contributes to liquidity and price discovery. Retail participation ranges from buy-and-hold investors in retirement accounts to active traders using margin or derivatives.

Institutional Investors

Institutions—mutual funds, pension funds, insurance companies, hedge funds, and sovereign wealth funds—manage large pools of capital and often drive liquidity and market trends. Their large orders can move prices, which is why execution quality and routing decisions matter.

Intermediaries: Brokers, Dealers, and Market Makers

Brokers execute orders on behalf of clients; dealers trade on their own accounts. Market makers quote bid (buy) and ask (sell) prices to provide continuous liquidity. The bid–ask spread compensates liquidity providers for risk and inventory costs.

Some intermediaries operate under quoting obligations to ensure fair and orderly markets. Investors should know the difference between execution on an exchange and internalized execution by a broker-dealer.

Other Participants

Exchanges, clearing houses, custodians, transfer agents, and regulators form the backbone of market infrastructure. Clearing houses interpose themselves between trade counterparties to manage counterparty risk; custodians hold securities for investors; regulators supervise and enforce rules.

Instruments Traded

Common instruments include:

Common stock: Ownership shares with voting rights and potential dividends.
Preferred stock: Shares with preferential dividends and priority over common stock in distributions.
Exchange-traded funds (ETFs): Baskets of securities traded like stocks that provide diversification.
Real Estate Investment Trusts (REITs): Pooled real estate investments that trade on exchanges.
American/Global Depositary Receipts (ADRs/GDRs): Vehicles that represent foreign company shares for local markets.

Derivatives such as options and futures are also traded on exchanges and OTC markets to hedge risk or gain leveraged exposure.

Price Discovery and Order Types

Supply and Demand and Quotes

Price discovery is the process by which markets aggregate information into a price. Visible bids and asks reflect participants’ willingness to buy or sell. The last traded price is a historical result; the best bid and best ask signify current near-term trading prices.

Order Types

Order types determine how and when trades execute:

Market orders: Execute immediately at the best available price.
Limit orders: Execute only at a specified price or better.
Stop orders (stop-loss): Convert to market orders when a trigger price is hit.
Stop-limit: Convert to a limit order at a trigger price.
Immediate-or-cancel (IOC), Fill-or-kill (FOK): Execution constraints that control partial fills and timing.

Choosing order types affects execution certainty, price certainty, and transaction cost.

Liquidity, Bid–Ask Spread, and Slippage

Liquidity measures how easily an asset can be bought or sold without moving its price. The bid–ask spread is an explicit cost for immediate execution; slippage is the difference between the expected trade price and the executed price. Thinly traded stocks typically have wider spreads and higher slippage risk.

Market Microstructure

Order Books and Matching Engines

Central limit order books (CLOBs) collect limit orders by price and time priority. Matching engines match compatible bids and asks to execute trades automatically. Market design—continuous trading, opening/closing auctions, and batch auctions—matters for price formation and volatility.

Role of Market Makers and High-Frequency Trading (HFT)

Market makers post continuous quotes and help tighten spreads. High-frequency trading algorithms provide liquidity and arbitrage across venues but can also amplify short-term volatility. Market makers balance quoting obligations against inventory and volatility risk.

Fragmentation and Best Execution

Trading is fragmented across multiple venues. Brokers have routing rules to seek the best execution for clients, considering price, speed, and likelihood of fill. Regulations require brokers to pursue best execution policies consistent with client best interests.

Clearing, Settlement and Custody

After a trade executes, clearing and settlement finalize the transfer of securities and funds. Clearing houses net trades, manage margin, and guarantee settlement by interposing central counterparty (CCP) risk mitigation.

Settlement cycles moved to shorter windows over time (for example, many markets use T+2 settlement: trade date plus two business days). Delivery versus payment (DvP) ensures that securities and payment exchange simultaneously, reducing counterparty exposure.

Custodians hold securities on behalf of investors, safeguarding assets and managing corporate actions, proxy voting, and tax reporting.

Regulation and Oversight

Regulators (e.g., the SEC in the U.S.) set rules for disclosure, fair dealing, market structure, and reporting. Self-regulatory organizations (SROs) like FINRA complement government agencies by enforcing rules on broker-dealers and ensuring conduct standards.

Regulation aims to reduce fraud, improve transparency, and protect investors. Surveillance systems detect irregular trading patterns and potential manipulation. Public companies must file periodic financial reports to ensure informed markets.

Market Indices and Benchmarks

Indices aggregate prices to measure market segments and serve as benchmarks. Construction methods include:

Market-cap weighting (e.g., a broad market index where larger companies have greater weight).
Price weighting (e.g., some legacy indices where higher-priced shares have more influence).
Equal weighting.

Indices guide passive strategies (index funds, ETFs) and provide performance comparison points for active managers.

How to Invest or Trade

Brokerage Accounts and Access

Investors open brokerage accounts (cash, margin, retirement) to access markets. Account types influence taxation, margin availability, and investment options. Bitget provides secure account access and custody solutions, and Bitget Wallet supports secure storage for digital assets and tokenized real-world assets where available through compliant products.

Execution and Costs

Costs include explicit fees (commissions, exchange fees) and implicit costs (spread, market impact, slippage). Large institutional orders often use algorithms to reduce market impact; retail investors may prefer limit orders to control price.

Long-term Investing vs. Trading

Long-term investing focuses on fundamentals, compounding, and lower transaction frequency. Trading seeks short-term gains from price movements and requires active risk management, cost controls, and understanding of tax implications (short-term vs. long-term capital gains). Neither approach guarantees results; choices depend on objectives and risk tolerance.

Risks, Volatility and Market Events

Markets carry several types of risk:

Market risk: Broad price declines affecting many securities.
Systemic risk: Failures that threaten the financial system.
Liquidity risk: The inability to transact without large price moves.
Operational risk: Failures in systems, clearing, or custody.

Events like flash crashes, corporate scandals, or macro shocks can produce rapid price moves. Diversification, position sizing, and understanding settlement/custody practices help manage exposure.

Market Efficiency and Theories

The Efficient Market Hypothesis (EMH) posits that prices reflect all available information. In practice, markets display varying degrees of informational efficiency; behavioral finance documents persistent anomalies and investor biases. These theories inform the active vs. passive management debate but do not prescribe a single investor strategy.

Comparison with Cryptocurrency Markets

Investors increasingly ask, "does the stock market work the same way as crypto markets?" The two markets share concepts—orders, custody, liquidity—but differ in key ways:

Trading hours: Traditional exchanges typically operate during set hours; crypto markets often run 24/7.
Regulation: Equities operate under mature regulatory regimes with disclosure and SRO oversight; crypto regulation is still evolving in many jurisdictions.
Custody: Equity custody is established via regulated custodians and depositories; crypto custody requires private key management and specialized custodians.
Instruments and tokenization: Tokenized stocks and RWAs (real-world assets) bridge TradFi and on-chain markets; such products raise custody, legal, and settlement considerations.

As of January 22, 2025, according to market reports, BitGo completed an IPO with notable first-day performance, and tokenization initiatives (e.g., Ondo Finance) are exploring on-chain representations of equities. These developments illustrate growing integration but also underline differences in regulatory frameworks and settlement mechanics between equities and on-chain tokens.

Common Misconceptions and FAQs

Is the market rigged? Market structure includes rules, surveillance, and enforcement to prevent fraud. While no system is perfect, regulators and exchanges work to detect and penalize manipulation.
Can you time the market reliably? Timing markets consistently is very difficult. Most retail investors improve outcomes with long-term discipline, diversification, and cost awareness.
Do exchanges create prices? Exchanges facilitate matching of buy and sell interest; prices originate from participants’ orders—supply and demand.

Practical Guidance and Best Practices

Diversify across assets and sectors to reduce idiosyncratic risk.
Understand explicit and implicit costs before placing trades.
Use suitable order types to control execution outcomes.
Keep a long-term perspective for retirement and core allocations.
Protect assets with reputable custodians; for digital assets, prefer Bitget Wallet for custody and Bitget services for compliant trading access where available.

Market Events and Timely Context

As of March 15, 2025, according to Politico, U.S.–China diplomatic engagement was reported to be increasing with potential multiple leader-level meetings. Markets often react to developments that affect geopolitical risk premiums; such diplomatic signals can influence sectors sensitive to trade and technology policies. This statement is strictly factual reporting of the announcement and not investment advice.

As of January 22, 2025, reports noted BitGo’s successful IPO debut and first-day trading performance. That event highlights how infrastructure firms in the digital asset space can access public capital markets. As of January 21, 2026, reports indicated substantial activity around tokenized stocks on high-throughput blockchains, with platforms issuing tokenized representations of dozens or hundreds of traditional assets. These developments illustrate that equities and tokenized products can coexist, but regulatory and custody distinctions persist.
