Stock (share)

What a stock means

A stock, also called a share or equity, is a unit of ownership in a company. If a company has issued one million shares and you hold ten thousand, you own one percent of it. That ownership gives you a claim on the company's assets and earnings, though it ranks behind lenders and bondholders if the business fails.

Companies sell shares to raise money for growth, to repay debt or to let early backers sell. When shares are listed on an exchange, anyone with a brokerage account can buy and sell them, and the price changes throughout the trading day as buyers and sellers agree on a level. The total value of all a company's shares is called its market capitalisation, which equals the share price multiplied by the number of shares outstanding.

Stocks come in two broad forms. Common shares typically carry voting rights and a variable dividend. Preferred shares usually pay a fixed dividend and have priority over common shares but often lack voting rights. The word "stock" is used in some countries for the ownership concept in general and "share" for a single unit, though most people use the two interchangeably.

How it works

A shareholder can gain or lose in two main ways.

• Price change: if you buy at 50 and the price rises to 60, you have an unrealised gain of 10 per share. If it falls to 40, you have a loss of 10.
• Dividends: companies can distribute part of their profit to shareholders. They are not guaranteed and can be raised, cut or suspended.

The share price is influenced by many things: company earnings, growth outlook, interest rates, sector trends, news and overall market sentiment. In the short term it can move sharply for reasons that seem unrelated to business results. Over the long run, prices tend to follow the company's earnings and cash generation, but there is no guarantee.

Buying shares works through a broker. You place an order, such as a market order or a limit order, which is matched on an exchange. The trade settles a short time later, one business day after the trade date in some markets, and the shares are recorded in your account. Many brokers now offer fractional shares, so you can invest a set amount rather than buying whole units.

Common measures used to compare stocks include earnings per share, the price-to-earnings ratio, dividend yield and market capitalisation. They are descriptive tools and do not predict returns.

A worked example

These numbers are illustrative only. An investor buys 40 shares of a company at 25.00 each and holds them for a year.

1. Purchase cost = 40 × 25.00 = 1,000. Suppose the broker charges a commission of 2.00, so total outlay = 1,002.
2. During the year the company pays dividends of 0.60 per share. Dividend income = 40 × 0.60 = 24.00. Assume a 15 percent withholding tax, which leaves 20.40.
3. The investor sells the shares at 28.00. Proceeds = 40 × 28.00 = 1,120, less a 2.00 commission, giving 1,118.
4. Total gain = 1,118 + 20.40 - 1,002 = 136.40. As a percentage of the outlay, 136.40 ÷ 1,002 = 13.6 percent.

Now consider the downside. Had the price fallen to 18.00, proceeds would have been 40 × 18.00 = 720 less 2.00 = 718. Total result = 718 + 20.40 - 1,002 = -263.60, a loss of about 26.3 percent. A single company can also fall to zero, in which case the shareholder may lose the whole investment.

Why it matters

Stocks are a core building block of investing. They offer the potential for growth and income over time, and historically they have been a major source of long-term wealth for many investors, though results vary widely by period and country. They also carry more price risk than cash or most bonds.

Costs matter. Commissions, spreads, currency conversion fees on foreign shares, custody fees and taxes on dividends and gains reduce what you keep. Brokers differ widely in their pricing and in the markets they offer. An investor buying a few times a year faces a different cost profile than an active trader.

Ownership structure matters as well. Buying actual shares gives you the rights of a shareholder, such as voting and dividends. A CFD on a share only tracks its price, with no ownership and often adjustments for dividends and financing.

How to use it in practice

1. Decide the purpose: long-term investing, income or short-term trading, since each calls for a different approach.
2. Research the company: its business, financial statements, debt, competitors and risks.
3. Check the broker's fees for the specific market, including commission, spread and currency conversion.
4. Choose an order type and size that fit your plan. A limit order gives price control.
5. Spread risk. Holding a number of stocks across sectors, or using funds, reduces the effect of a single failure.
6. Understand how the investor compensation scheme and custody arrangements apply to your account.
7. Keep records of purchases, dividends and sales for tax reporting.

Common mistakes and misconceptions

• Believing a low price per share means cheap. A 5 share price tells you nothing without the number of shares and the company's value.
• Concentrating on a single stock. Company-specific events can cause large, sudden losses.
• Chasing recent winners. Strong past performance does not predict future results.
• Ignoring costs and taxes, which can erode returns over time.
• Treating dividends as guaranteed. They can be cut at any time.
• Confusing owning a stock with trading a CFD on it. They differ in rights, costs and risk.

Risks and limitations

Share prices can fall significantly and stay low for years. Individual companies can go bankrupt, leaving shareholders with nothing since creditors are paid first. Market-wide declines affect most stocks at once, so diversification reduces but does not remove risk. Currency movements affect foreign holdings. Margin borrowing or leveraged products such as CFDs can lead to losses larger than the original stake in some structures. Past performance is not a reliable guide to the future.

How Brokeli looks at it

When we review brokers, we check which stock markets are available in each country, whether real shares or only CFDs are offered, how commissions, spreads and currency conversion are charged, and how custody and compensation arrangements work. Those details come from the published research snapshot. We do not suggest which stocks to buy.
