What is a Stock Market?
A stock market is a regulated platform where buyers and sellers trade shares of publicly listed companies and other financial instruments like bonds and derivatives.
It enables companies to raise capital through share issuance (primary market) and investors to trade these shares (secondary market), reflecting economic activity and corporate performance.
Purpose:
Facilitates capital allocation, investment, and wealth creation.
Function:
Matches buy and sell orders, sets prices via supply and demand, and ensures transparency under regulatory oversight.
Examples:
Platforms like stock exchanges globally, regulated by authorities (e.g., SEC in the U.S.).
How Does a Stock Market Work?
The stock market operates through a structured process involving exchanges, participants, and technology, driven by trading and settlement mechanisms.
Here’s a clear overview:
Company Listing:
Companies issue shares via Initial Public Offerings (IPOs) in the primary market to raise funds.
Shares are listed on exchanges after meeting regulatory standards.
Trading Process:
Investors place buy (bid) or sell (ask) orders through brokers, matched by the exchange’s order book.
Prices fluctuate based on supply, demand, company performance, and economic factors.
Order Types:
Market orders (immediate execution), limit orders (specific price), stop orders (triggered at a threshold).
Trading Platforms:
Historically, trading occurred physically on exchange floors; today, electronic systems enable automated, high-speed trading.
Investors access markets via brokers or online platforms.
Clearing and Settlement:
Clearing houses verify trades, ensuring both parties fulfill obligations.
Settlement transfers shares and funds, typically within one day (T+1 in many markets by 2025).
Depositories hold shares electronically, eliminating physical certificates.
Indices:
Market indices (e.g., weighted averages of selected stocks) track performance, serving as economic indicators.
Regulation:
Regulators enforce rules on trading, disclosures, and fraud prevention, using tools like circuit breakers to pause trading during volatility.
Technology:
Modern markets rely on electronic trading systems, algorithms, and high-frequency trading (HFT), with retail investors using mobile apps.

History of Stock Market Trading: Evolution of Practices
This section focuses on how stock market trading was conducted at its inception and how methods evolved over time, excluding specific Indian or global exchange histories (e.g., BSE, NSE, NYSE events). The focus is on trading practices, from manual to digital systems.
13th–16th Century: Pre-Stock Market Trading
How Trading Was Done: No formal stock markets existed. Merchants in medieval Europe (e.g., Venice, Antwerp) traded goods, bonds, and early financial contracts informally, often at trade fairs or ports. Shares in joint ventures (e.g., shipping expeditions) were negotiated privately among wealthy investors.
Key Features:
Trading was face-to-face, undocumented, and limited to elites. No standardized prices or exchanges; agreements relied on trust.
Changes: By the late 1500s, Antwerp’s bourse introduced a physical venue for trading bonds and commodities, setting the stage for organized markets.
1602–1700s: Birth of Formal Stock Trading -
How Trading Was Done:
The first stock exchange emerged in Amsterdam (1602), trading shares of the Dutch East India Company. Investors gathered in a physical marketplace, shouting bids and offers (open-outcry system). Shares were issued as physical certificates, traded via handwritten contracts.
Key Features:
Trading was public but chaotic, with no real-time price dissemination. Brokers acted as intermediaries, recording trades manually. Share ownership was verified through physical documents.
Changes:
Standardized share issuance allowed broader participation.
Coffeehouses in London (late 1600s) became informal trading hubs, evolving into organized exchanges.
Speculative bubbles (e.g., South Sea Bubble, 1720) highlighted risks, prompting early regulations.
1700s–1800s: Open-Outcry and Physical Exchanges -
How Trading Was Done:
Stock exchanges formalized in London (1773) and other cities, using open-outcry trading on physical trading floors.
Brokers and traders shouted or used hand signals to place orders, with chalkboards displaying prices. Physical share certificates were exchanged post-trade.
Key Features:
Trading was limited to exchange members, conducted during fixed hours. Price information spread slowly via newspapers. Settlement took days or weeks, with risks of default.
Changes:
Specialized roles emerged (e.g., brokers, jobbers) to streamline trading.
Ticker tapes (late 1800s) introduced near-real-time price updates, improving transparency.
Railroads and telegraphs enabled faster communication, expanding market access.
Early 1900s: Standardization and Regulation -
How Trading Was Done:
Open-outcry remained dominant, with traders crowding exchange floors.
Stock tickers and telegraphs disseminated prices faster.
Physical certificates were stored in vaults, with manual settlement processes.
Brokers used ledgers to track trades.
Key Features:
Trading was still labor-intensive, with errors common. Retail investors relied on brokers for access. Major crashes (e.g., 1929) exposed manipulation risks.
Changes:
Regulatory frameworks emerged (e.g., U.S. Securities Act, 1933) to curb fraud and ensure disclosures.
Standardized contracts and clearing houses reduced settlement risks.
Telephone trading allowed remote order placement, broadening participation.
1960s–1980s:
Early Automation and Derivatives
How Trading Was Done: Open-outcry persisted, but computers began supporting back-office tasks (e.g., record-keeping). Some exchanges introduced electronic quote systems, displaying bids/asks on screens. Physical certificates remained common, though settlement delays persisted.
Key Features:
Trading floors were noisy, with human brokers central to price discovery. Derivatives (futures, options) gained popularity, requiring complex calculations. Retail access grew via mutual funds.
Changes:
Computers automated trade matching in smaller markets, reducing errors.
Electronic communication networks (ECNs) emerged, enabling after-hours trading.
Dematerialization began, replacing physical certificates with electronic records in depositories.
1990s–2000s: Electronic Trading Revolution -
How Trading Was Done:
Electronic trading platforms replaced open-outcry in many markets, using automated systems to match orders. Traders used computers to place orders, with real-time price feeds on screens. Dematerialized shares were held in electronic accounts, streamlining settlement.
Key Features:
Trading became faster, cheaper, and accessible globally. Online brokerage platforms allowed retail investors to trade directly. High-frequency trading (HFT) emerged, using algorithms for rapid trades.
Changes:
Screen-based trading (e.g., introduced globally in the 1990s) eliminated physical floors in many exchanges.
Internet trading democratized access, with retail platforms offering low-cost trades.
Derivatives markets expanded, with electronic systems enabling complex products.
Settlement times shortened (e.g., T+3 to T+2), reducing risks.
2010s–2025: Digital and Algorithmic Trading -
How Trading Was Done:
Fully electronic trading dominates, with orders executed in milliseconds via advanced platforms. Retail investors use mobile apps for instant trades, accessing real-time data and analytics.
HFT and algorithmic trading account for over 60% of global volumes.
Blockchain and AI are emerging for settlement monitoring and fraud detection.
Key Features:
Trading is global, 24/7, and highly automated.
Settlement is T+1 or real-time in advanced markets.
Retail participation has skyrocketed, with social media influencing sentiment.
ESG (Environmental, Social, Governance) and crypto-linked securities are traded actively.
Changes:
Cloud-based platforms and APIs enable seamless integration for brokers and investors.
Dark pools and alternative trading systems allow large trades without market impact.
Regulatory tech (RegTech) monitors trades in real-time.
Decentralized finance (DeFi) platforms experiment with blockchain-based securities trading, though regulated markets remain dominant.
