How Does a Stock Market Work?

A stock market or stock exchange is a place where you can purchase, sell or trade stocks during week days (Mon to Fri).  The stock exchange is medium for buyers to own a share of corporations or public companies. It functions quite like an auction, where investors are urged to purchase or sell a share of their stocks.

During the stock exchange trading hours, buyers and sellers estimate share prices, based on the supply and demand. Investors have the opportunity to bid a price of a particular stock if they believe that the company would perform well in the foreseeable future.

In the stock market, sellers aim to attain a high value for their stock holding. The aim is to sell their stock holding at a higher price than previously bought. Similarly, the objective of the buyers is to buy the stocks, as low as they can, while aiming to earn a high profit when sold.

Stock markets operate regionally, as well as globally. In global stock markets, the participating companies include firms from around the globe. Whereas, a regional stock exchange comprises of firms within the country. They are not located in the primary financial centre of country. For example, in US, Boston, Chicago, Pacific and Philadelphia are the four major regional exchanges.

What is a Stock?

A stock is a form of ownership of a portion of a corporation or a public company. Owners of the stock have the right to own assets and revenue, generated by the firm, based on the percentage of their ownership. The units of stock are referred to as “shares”. Shares of publicly trading company can be bought or sold in a stock exchange. Essentially, there are four types of stocks that you can invest in.

Growth Stocks

These stocks are shares in the firms that are expected to expand and grow at an above-average rate, in contrast to the market. These companies bring in a positive flow of income.

Dividends or Yield stocks

In dividend or yield stocks, you are paid an income, based on the revenue generated by the company. The dividend yield is calculated by dividing the yearly dividends paid by the firm, by the price of the share.

Initial Public Offerings

An IPO is a process of presenting the shares of a private company to the public when new shares are issued.  Once the shares are listed on the exchange, any individual, institutional or pension fund has the liberty to invest in it.

Defensive stocks

Defensive stocks are those shares that are not much effected by the fluctuations of the economy. These are non-cyclical stocks, which means that they are not parallel with the overall economy. Hence, these include items such as food, oil and basic utilities. Defensive stocks provide a consistent dividend, as individuals still consume these items during an economic recession.

Shares are purchased and sold on a stock exchange. With the help of internet, there are several platforms (or brokers) that allow the process of buying or selling of shares to be carried out on your fingertips. With that said, the stock exchange process must conform to the regulations set aside by the governing body.

Private companies usually raise capital in the form of issuing stocks. These stocks provide them with the necessary funds and monetary incentives that are required to get their business up and running.

Once the investments are made, the issued (share) capital is assigned. This is an amount, demonstrated by a nominal value, which signifies the share held by the shareholders. For example, if a start-up firm sold 100,000 shares, with the face value of £ 1 per share, in such a case, the issued share capital of the company would be £ 100,000.

The stock exchange process plays a vital role in improving the health of the economy in any country. With more individuals and institutions investing in stocks, more firms would have the monetary incentive to get their businesses up and running.

Considering this, the stock market can offer financial benefits to the overall economy of the country.

What is a Stock Exchange?

While the stock market is a collection of buyers and sellers, who make trades in stocks, the stock exchange is the building or infrastructure that fosters the process of making this trade.

The stock exchange is an organisation that empowers companies to list down their shares, so they can be sold to the public.

The stock market features all firms and enterprises, dealing with different industries, to list their shares for the investors to consider making an investment in. The stock market features both primary and secondary markets and it is an amalgamation of over the counter trading, electronic trading, as well as stock exchanges. Essentially, the stock market is the platform that facilitates the trading, so that companies can raise capital that could be used to generate income in their specific business.

The stock market can be referred to as ‘bullish’ or ‘bearish’. These titles are given out the basis of the thought process of traders. A bullish stock market is when investors prefer to buy shares that they consider will rise in value in the future. On the other hand, the bearish stock market is when investors think that the market will decline in value in nearby future, thus try to sell their investment.

Stock exchanges in every country are regulated by SECs (Securities and Exchange Commission) that allow the trading process by establishing rules and regulations for the listings. The stock exchange provides services to individual investors, traders, brokers and institutional investors, while also keeping track of the changes in the prices and trading volumes. Considering this, the stock exchange is a platform which allows buyers and sellers to interact with one another, at a mutually stated point. The stock exchange may be virtual or physical.

For example, the London Stock Exchange, located at Paternoster Square, facilitates the conduction of all activities being carried out in the primary, secondary, main markets and alternative investment markets. Based on the analysis conducted in April 2018, the London Stock Exchange has a market capitalisation of US$4.59 trillion.

How does it work?

The stock market works by creating a platform for companies to list down their available shares or floats, for investors to invest their money into.

The shares of the prices enumerated on the stock exchange are determined by the supply and demand phenomenon. The law of supply and demand is responsible for hiking up or reducing the prices of different stocks.

When the demand is low, and the availability of the product is high, the prices naturally decrease. During this time, investors purchase good value the shares at low prices, in the hope of attaining a profit when the market price fluctuates upwards and they can sell their investment at a higher rate. Similarly, when the demand is high and the availability is low, the share prices go through the roof.

In the stock market, the prices are affected by three elements- the state of the economy, the interest rates and corporate results. If the economy is doing well, the demand for stocks become high. This is because consumers would have the money to buy the products or services being offered. Hence, with high demand, there would be a greater revenue for the listed companies.

On the other hand, the rise in interest rates negatively influences demand. This is because the risk-free rate of return is increased. However, the interest rates tend to only rise when the economy is doing well for itself. Therefore, this element does not play a significant role in impacting the stock market, as its influence is typically balanced out by the increase in demands, led by an improved economy. Interest rates can influence investors decision whether to invest in stock market or to invest in interest bearing account – which ever is high. Interest rates have the historic low recently so it makes sense to invest in stock market.

The corporate results have the most significant impact on the stock market. As companies make sale and generates profits, they substantially influence the stock price at the stock exchange.

In addition to this, the number of buyer and sellers also influence the stock market. For instance, for a stock transaction, there must be a buyer and a seller. If the number of buyers is larger than the number of sellers, the price of the stock can rise, as the demand becomes high. To understand this better, you can take a look at the following scenario.

If you start a business of selling chocolate cake in innovative designs, that no other business can create, you would have a large number of buyers. Due to this popularity, and no other competitor, you would have the opportunity to raise the prices of your goods. Hence, you would be able to decide the price. Similarly, the prices in the stock market can fluctuate if there is a discrepancy between the number of buyers and sellers.

For the stock market to function effectively, there is a need for buyers, sellers, dealers, brokers, and market makers. The role of the buyers and sellers is quite literal. However, the brokers are individuals who authorize an investment on an investor’s behalf, by utilising their knowledge of the stock market. Brokers assist in helping buyers and sellers settle on a sale of stocks.


On the other hand, market makers involve individual institutions, such as the banks, who make sure that there is liquidity in the market that facilitates the exchange of stocks. Market makers, essentially, ensure that there is an ample volume of trading so that the trades can be carried out without any problem.

Ways of investing in stocks

If you wish to invest in stocks, there are traditional, as well as new ways in which you can achieve your objective. Before you make an investment, you must gauge an idea of what type of investor you are. If you have knowledge about the fluctuation of the economy, as well as the trends in the stock market, you can make an investment yourself. However, if you need professional assistance and a guide to help you out throughout the process, you have a few options that allows you to work with an expert.

Invest in Mutual or Index funds

The only difference is mutual funds are professionally managed by experts, hence why their fees or expense ratio is higher. Index funds on the other hands are also similar to mutual funds or ETFS but index funds provide a broad market exposure. An index fund is built in a way to track financial market such as S&P 500. It is simple, diversified and an affordable way of investing in the stock market.
