Introduction
The stock market is a global system where people buy and sell shares of publicly traded companies, enabling businesses to raise capital and investors to build wealth through ownership, dividends, and price appreciation. It is not a single location, but an intricate network of exchanges, brokers, and electronic platforms where securities change hands every business day.investopedia+2
Understanding the Basics
What Is the Stock Market?
The stock market is comprised of various marketplaces such as the New York Stock Exchange (NYSE), Nasdaq, London Stock Exchange, and more, each regulated and equipped to ensure fair and transparent trading. Companies list their shares on these exchanges in order to raise capital for growth, while investors purchase shares to participate in business profits and vote in company matters. These purchases represent partial ownership; as companies thrive, share values typically rise, generating returns for investors.getsmarteraboutmoney+4
Stock Exchanges and Trading
Stock exchanges function as organized platforms or “auction houses” where buyers and sellers are brought together to determine prices through supply and demand. Most stocks are bought and sold electronically, and exchanges enforce strict regulatory standards to protect participants and promote market integrity. Investors use brokers—either traditional or online—to execute trades. Market makers provide liquidity, ensuring shares can always find a buyer or seller at current prices.getchip+2
How Prices Are Set
Supply, Demand, and Price Discovery
Stock prices are determined by the collective actions of buyers and sellers agreeing on values in real time. When demand for a stock increases—driven by positive news, strong financial results, or investor optimism—its price rises. Conversely, when supply outpaces demand, prices drop. Factors influencing prices include company performance, broader economic trends, interest rates, political events, and market sentiment. Exchanges provide continuous pricing information, enabling investors to respond rapidly to developments.investopedia+1
Market Structure and Roles
Primary and Secondary Markets
Companies first issue shares in the primary market through initial public offerings (IPOs). Once shares are issued, they trade on the secondary market, where investors buy and sell among themselves, and companies are no longer part of the transaction. This structure facilitates efficient capital raising and wealth creation.flame+2

Investing and Risk
