How are shares traded?

Most major shares are traded on the stock market. This is a general term for a global network of specific exchanges where shares are bought and sold.

For example, the majority of UK shares are traded on the London Stock Exchange (LSE), while most US shares can be found on the New York Stock Exchange (NYSE) or NASDAQ.

These exchanges are highly-regulated marketplaces where buyers and sellers come together to negotiate the transaction of shares. Only certain qualified individuals are allowed to trade physically on the exchange itself, so investors generally need a stockbroker to act as a middleman.

What is a stockbroker?

The role of the stockbroker is to buy and sell stocks on their clients’ behalf. Traditionally, an individual investor would need to call up their broker, who would then relay the trading instructions to a qualified dealer on the exchange. Nowadays, however, this process is almost always conducted online.

There are three main types of broker:

When choosing a broker it’s important to consider your knowledge of the markets as well as the amount of time you’re prepared to commit to watching your portfolio.

Trading times

Shares are only traded during the opening hours of their designated stock exchange. Here are the opening and closing times of a few major exchanges (UK time, April – October. Opening times will be different throughout the rest of the year due to local daylight saving time changes):

How do shares become listed on an exchange?

Companies are either privately owned or public.

A private company isn’t listed on a major stock exchange, so you would usually have to contact the owners directly to buy shares. Even then, they are under no obligation to sell them.

However, if the owners want to ‘go public’ to raise some capital or boost the company’s reputation, they must carry out an initial public offering, or IPO. Following an IPO, the company’s shares are listed on a stock exchange and ordinary investors can buy and sell them.

Publically-listed companies often have many more shareholders than private ones, and are subject to much tighter regulations. The exact rules tend to differ depending on the exchange, but generally a public business needs to appoint a board of directors and disclose detailed financial information at least twice a year.

Dividends

A key advantage to investing in shares is the potential for dividends.

A dividend is an amount of money paid to shareholders, representing a portion of the company’s profits.

When a company makes a profit, the management get to decide how much to put back into the business and how much to pay to the shareholders as a dividend.

Dividends can compensate for a share price that isn’t moving much, giving shareholders an income instead. Companies that are expanding rapidly usually don’t offer dividends, choosing instead to reinvest all their profits to sustain growth. The reward for shareholders in this case is a higher expected share price in the long run.
