Understanding Equities  •  Lesson 1 of 7

Equity markets in the form of stock exchanges exist all over the world. They form a global ecosystem that helps businesses grow and investors build wealth. Once listed on an exchange, anyone can buy or sell shares of the company and these are the reasons why you might want to take that approach.


The equities market is where buyers and sellers come together to trade shares of companies. This article will explain the basics of the equity markets, how they work, and help you determine whether stock investing is right for your portfolio.

What are equities?

Equities, commonly referred to as stocks or shares, represent ownership in a company. When you buy a stock, you’re purchasing a small piece of that company. If the company becomes more successful and its value increases, your shares can become more valuable as well.

While you will be a part-owner of a company, your ability to influence decision-making will be determined by the number of shares you hold and the voting rights attached to them. Most investors are, therefore, minority shareholders with limited scope for determining the way companies they hold stocks in will operate.

Being a smaller shareholder means that from an investment perspective, you need to identify the type of company into which you will be buying. Some companies, for example, are known to share profits with shareholders by paying dividends, while others reinvest their profits to fund growth.

What is the equities market?

The equities market (or stock market) is a marketplace where stocks are bought and sold. Companies list their shares on stock exchanges to raise capital, and investors buy these shares to participate in the potential growth of those businesses.

The US equities market is made up of a network of venues that match buyers and sellers. In the US, it includes major exchanges like the New York Stock Exchange (NYSE) and Nasdaq® as well as smaller regional exchanges. In fact, there are 17 regulated exchanges in the US.

Who can participate in trading stocks?

The main participants in the stock market include retail and institutional investors who engage in stock trading to generate an investment return; other parties such as brokers and market makers provide a service which helps stock markets to function effectively.

  • Retail investors – individuals who are investing for their personal investment account.
  • Institutional investors – Large firms such as mutual funds, pension funds, hedge funds.
  • Market makers – Firms that continuously buy and sell stocks to ensure liquidity in the market.
  • Brokers – Intermediaries that connect buyers and sellers, often through online trading platforms.

Tip: In the US, pay attention to regulatory filings like 13F reports for insights into what institutional investors are doing.

What determines a stock’s price?

Stock prices are driven by supply and demand. If more people want to buy a stock than sell it, the price usually goes up. If more people want to sell than buy, the price goes down.

Stock prices can fluctuate intraday and are affected by such factors as company performance, industry news, economic trends, and investor sentiment.

What drives investor sentiment?

Investor sentiment is driven by both societal factors, such as the impact of the global geopolitical landscape, as well as financial factors determined by market research and analysis.

  • Rational sentiment is based on facts, such as a stock buyback or strong earnings reports.
  • Irrational sentiment is based on intangibles such as fear or hype including geopolitical uncertainty or social media influencers. In worst case scenarios, this fear can lead to a herd mentality and can amplify market volatility or lead to price movements.

Tip: Monitor market activity to track stocks experiencing large trade volumes or extreme price moves.

How do you potentially make money in the stock market?

Two ways to potentially make money when investing in stocks include receiving dividend income and capital gains which occur when you anticipate increases in a stock’s value over time. These factors aren’t mutually exclusive and some stocks will offer both an income stream and capital growth.

  • Dividends – Companies can choose to pay out profit to shareholders on a quarterly, semi-annual or annual basis. Investors can take the cash in hand or reinvest it to buy more shares and the total amount of dividend received will be based on how much stock an investor owns.
  • Capital Appreciation – When the price of a stock increases after it is purchased by an investor.

EU disclaimer: Forecasts are not a reliable indicator of future performance

Tip: Remember, not all companies pay dividends, and stock prices can go up or down. Investing always carries risk.

What are the risks of investing in stocks?

There are many different types of risks when investing in stocks, but the main ones include market risk, company-specific risk, and economic risk.

  • Market risk When the overall market drops due to factors like inflation or geopolitical events.
  • Company-specific risk – Issues specific to a business, such as poor earnings or bad management decisions.
  • Economic risk – Broader factors such as recessions, inflation, and interest rate changes, which form part of the macroeconomic cycle and affect all companies.

Tip: Diversifying your investments (owning different types of stocks or sectors) can help to reduce risk.

Final Thoughts

When a company chooses to be publicly traded, it creates an opportunity for investors to own a share of that company. For new investors, the equities market can seem complex, but it’s a popular market due to the potential to build long-term wealth.

Maybe you want to invest in your favourite businesses or maybe you have an interest in a particular sector – just remember that there is always risk as past performance does not indicate future results.
