What is a stock: ownership, dividends and how the market works
A stock — often called a share — represents part ownership of a business. Buy one and you hold a small slice of the company's assets and future earnings, along with a vote at meetings in many cases. The slice is proportional: the more shares you own relative to the total in issue, the larger your stake in whatever the business earns or loses.
Why companies issue shares
Firms sell shares to raise money without borrowing. The proceeds might fund new equipment, expansion, research or simply strengthen the balance sheet. Once issued, those shares can change hands between investors, which is what gives the market its liquidity. The company itself does not receive money when existing shares trade; only the initial sale puts cash in its coffers.
How an ordinary shareholder earns or loses
Two channels matter. The first is the price: if demand for the shares rises, the quoted value climbs, and selling above your purchase price produces a gain. If sentiment sours, the quoted value falls and a sale below your cost produces a loss. The second channel is the dividend — a distribution of profit the board chooses to pay, usually in cash, sometimes as additional shares. Dividends are not automatic and can be cut or skipped.
- Price movement: the difference between what you paid and what you receive on sale.
- Dividends: periodic payouts from profits, decided by the board.
- Total return: the combination of both, before costs and taxes.
The exchange as a marketplace
Buyers and sellers meet through an exchange, which operates the trading system, publishes prices and sets listing rules. On the Johannesburg Stock Exchange, companies that satisfy those rules have their shares quoted, and investors place orders through members of the exchange. The exchange does not set prices; supply and demand do.
What an index tells you
An index tracks a basket of shares and expresses their combined movement as a single figure, making broad market direction easier to read than watching each counter separately. The all-share index covers a wide spread of listed businesses, so it is often used as a rough gauge of overall market sentiment rather than a verdict on any single company.
Risks to keep in view
Equity investment carries no guaranteed return. Prices can fall and stay low for long stretches; dividends can shrink; a company can fail. Concentration in a single share magnifies that risk. Past movement says nothing certain about what comes next, and holding costs, taxes and currency effects all nibble at outcomes.
