How does the stock exchange actually work?
Stock exchanges play a key role in the financial market and economy. They are also crucial for you as an investor. We explain how the stock exchange works.
A stock exchange is essentially like a marketplace – buyers and sellers come together to trade commodities or securities. The stock exchange is extremely important for investors. It is where they trade securities and where companies raise capital. There are two different types of market: the primary market and the secondary market.
Primary market: companies raise capital
Companies raise money on the primary market. They issue shares or bonds which are bought by investors. In the case of shares, companies usually raise equity on the market through a stock market flotation or capital increase. If companies issue bonds, they raise debt capital.
Here is an infographic that explains how the stock exchange works. There is an icon at the bottom which symbolizes the company. A second icon next to it symbolizes the investor. An arrow points from the company to a grey rectangle symbolizing the stock exchange. This means that the company is issuing securities. Another arrow points from the investor towards the stock exchange. This means that the investor is investing money. In the stock exchange. The investor’s money is exchanged for the company’s securities on the stock exchange. This is represented by a securities icon and an icon depicting notes and coins. The two icons are connected to each other by two arrows pointing in opposite directions.
Secondary market: investors trade securities
Shares and bonds are traded on the secondary market. Their price is determined by the principle of supply and demand. The latter is based on the expectation of future gains. This means the price – in other words, the value of the security – is constantly changing. If lots of traders want to buy a particular share, then its price rises. Conversely, the price falls if many of them want to sell it off. In this case, demand affects the price, as the quantity of the offer remains the same.
Here is a graphic that illustrates how the secondary market works. The rectangle at the top symbolizes the stock exchange. It contains a securities icon and a money icon depicting coins and notes. There are two icons at the bottom that represent investors. One of the investors wants to sell securities. An arrow is pointing upwards from him towards the stock exchange. The other investor wants to purchase securities. There is an arrow pointing down towards him from the stock exchange.
