Everyday, stocks are exchanged and traded in numerous stock markets across the world. The liquidity they bring in is a vital component of economic growth. However, we seldom give the role of stock exchange any thought.

This article provides some basic information about stock markets.

What is a stock exchange?

A stock exchange is a corporation or an organisation which provides 'trading' facilities for stock brokers and traders to trade stocks and other securities. The securities traded on a stock exchange include: shares issued by companies, unit trusts, derivatives, pooled investment products and bonds.

Simply put, stock exchanges are open markets that trade financial assets. Whether associated with a company or acting as an individual, a stock exchange is the place where stocks are bought and sold.

There are a number of major stock exchanges around the world and each of these plays a part in determining the overall condition of any economy.

What is the role of a stock exchange which makes it vital to an economy?

The main function of a stock exchange is to facilitate the transactions associated with both the buying and selling of securities. Buyers and sellers of shares and stocks can track the price changes of securities from the stock markets (derivatives, equity etc.) in which they operate.

Also, stock exchanges have multiple roles in an economy which make it vital. These include:

With the help of stockbrokers, the buyers and sellers participating in a stock market carry out their transactions. The brokers representing selling parties take their orders to the stock exchange floor and then find brokers representing parties willing to invest in similar stocks. If both parties agree to trade at the fixed price, the transaction takes place.

What are the requirements to trade in a stock exchange?

Companies have to meet the requirements of the exchange in order to have their stocks and shares listed and traded. These requirements vary from exchange to exchange. However, the common necessity for a security to be traded on a certain stock exchange, it has to be listed there. Trade on any exchange can be done by members only.
