What is a stock exchange?

Definition and meaning: what is a stock exchange?

A stock exchange is a centralised location where the shares of publicly traded companies are bought and sold. It’s important to note that the stock exchange differs from other markets where securities are bought and sold, because the tradable assets are limited to shares, bonds and other financial instruments like exchange traded funds (ETFs).

Sellers of stocks initially comprise of companies that turn to the exchange for the purpose of raising capital – through selling equity – and providing interested members of the public the opportunity to buy and trade shares.

If you want to take ownership of the company shares, the stock exchange is where the equity will be listed. It’s important to note that the company stocks are not sold by the exchange, though the sale is facilitated there.

Some of the most popular exchanges in the world include the New York Stock Exchange (NYSE), the NASDAQ, and the Tokyo Stock Exchange (JPX). Other well-known stock exchanges include the London Stock Exchange (LSE), the Shanghai Stock Exchange (SSE) and the Bombay Stock Exchange (BSE).

How are share prices on stock exchanges set?

The stock exchange mirrors the marketplace where the supply and demand of shares determines the price. The seller of the stock will present the initial value and – like in an auction – there’ll be bids from buyers for the shares until they settle on the price.

The initial share price is set based on various factors, like the company’s expected long-term earning potential, which can attract or repel buyers. Over time, the performance of the company (tracked over four quarters of a fiscal year) can increase the price, especially when there’s a high demand. Conversely, poor performances will have an adverse effect, in which investors could opt to sell their stock.

While internal events in the company can impact the share price (like changes in management, quarterly performances, etc.), external changes in the market can also influence the value of the stock. For example, political and economic events can restrict or improve the company’s potential to meet its expected returns, which can impact the share price.

How is a stock exchange different to the stock market?

The stock exchange is a physical infrastructure – although accessible digitally – that enables buyers and sellers of shares to meet in a common place where their transactions can be regulated.

The stock market, on the other hand, is an all-encompassing term that refers to the non-physical place where financial transactions of listed companies take place. The transactions performed in the stock market are conducted through an exchange or over-the-counter (OTC) marketplace.

The two terms may be used interchangeably; however, they represent two different things. The stock market functions as a result of the existence of stock exchanges. Investors can track real-time pricing information from the stock exchange, then decided to buy or sell the shares in the market.

Stock exchanges vs over the counter (OTC) trading

Over-the-counter or OTC trading refers to the buying and selling of securities that’s not conducted on a formal exchange venue or platform. Instead, it’s a decentralised market, where most trades are performed between two parties (the buyer and seller) and are often handled via a dealer network.

Unlike exchange-based trading, OTC trades are less regulated, which creates a range of opportunities – but also some risks, which you need to bear in mind.

The main difference between using a stock exchange and OTC methods of trading is that, on an exchange, transactions are mediated rather than taking place directly between two parties. This means that there are stricter regulations imposed on investors and speculators, as well as on the companies listed.

There are different ways that institutions get listed on an exchange, either via a Special Acquisition Purpose Company (SPAC) merger, an Initial Public Offering (IPO) or direct listing.

3. Open an account or practise on a free demo
4. Select your opportunity
5. Set your position size and manage your risk
6. Place your deal and monitor your position

Trade using CFDs

You can get exposure via derivatives trading, where you don't take ownership of the stock, but speculate on its price rising and falling. Using CFDs, you’ll trade on leverage, where you’ll need 20% of the full value size as your deposit to open a position.

You should remember that leverage trading will amplify your risk, as both your profits and losses will be calculated based on the full size of your trade, not the deposit you used to open the position. Therefore, it’s important to take steps to manage your risk.
