What does a share represent?
A share is one unit of ownership in a company. If a company has one billion shares outstanding and you own 100 shares, you own a tiny fraction of that company. That fraction may entitle you to voting rights, dividends, or other shareholder benefits depending on the share class and company policy.
The key idea is simple: a stock connects to a real business. The company may sell products, hire employees, borrow money, report revenue, and publish financial statements.
Why do companies issue stock?
Companies issue stock to raise capital, give early investors liquidity, compensate employees, or allow public investors to participate in ownership. When a private company lists on a public exchange, investors can buy and sell its shares more easily.
Public listing also brings reporting duties. Companies must disclose financial information, risk factors, executive compensation, and material events.
Why stock prices move
Stock prices move when expectations change. Earnings, revenue growth, margins, interest rates, competition, regulation, management decisions, and investor sentiment all matter. A company can be excellent and still fall if investors expected even more. A weak company can rally if expectations were too pessimistic.
This is why stocks are about both business reality and market psychology.
Stocks vs crypto
A stock is usually a legal claim on a company. Bitcoin is not. Ethereum is not. Many crypto tokens do not give holders ownership of a business, legal cash flows, or shareholder votes. They may have network utility, governance rights, staking use, or no durable use at all.
