Trading volume is a fundamental concept in the world of financial markets, playing a crucial role in determining the health and vitality of any asset or security being traded. It is all about keeping tabs on how many shares or units of an asset change hands during a specific period, usually a day. This simple metric offers valuable insights into the health of the market, price trends, and what investors and traders are thinking. More than that, it reveals what everyone in the market is thinking and doing. By looking at trading volume, we can tell if people are really interested in a particular thing and whether there might be good chances or risks for investors.

Volume of trade explained

Now that we have got a basic idea of what trading volume is, let us take a closer look at how it works and why it matters.

1. Measuring the number of transactions

At its core, trading volume is all about counting the number of transactions taking place in the market. Each time a share of a stock or any other financial asset changes hands, it adds to the trading volume. So, if 100 people buy 100 shares of a company's stock, that is 100 transactions, and it contributes to the trading volume for that stock.

2. Gauging market activity

Trading volume provides an instant snapshot of market activity. When trading volume is high, it means a lot of buying and selling is happening. This often suggests a more active and possibly volatile market. On the other hand, low trading volume can indicate a quieter, less turbulent market.

3. Interpreting market sentiment

Think of trading volume as a gauge of market sentiment. High trading volume typically means a lot of investors are actively participating. It may indicate optimism or pessimism about a particular asset. For example, a sudden surge in trading volume for a stock might signal excitement about a new product or fear of a financial crisis.

4. Role in price movement

Trading volume is closely tied to price movement. In general, a surge in trading volume can lead to significant price changes. If a stock's trading volume suddenly spikes, it can push the price up or down, depending on whether more people are buying or selling. So, trading volume helps us understand why prices are going up or down.

5. Liquidity and impact

Liquidity refers to how easily an asset can be bought or sold without significantly affecting its price. High trading volume usually means greater liquidity. It is easier to buy and sell when trading volume is high because there are plenty of buyers and sellers in the market. On the other hand, low trading volume can lead to less liquidity, making it more challenging to find a buyer or seller without affecting the price.

In essence, trading volume is like the heartbeat of the market, indicating its health and mood. It tells us if the market is buzzing with activity or if it is relatively quiet. Understanding these concepts is a valuable skill for investors and traders. In the next section, we will explore how trading volume can be used for making informed investment decisions.

Example of trading volume

To make the concept of trading volume even clearer, let us delve into a practical example.

Imagine you are considering investing in ABC company, which manufactures innovative tech gadgets. You have been keeping an eye on their stock for a while, and today you notice something intriguing: a sudden surge in trading volume. The stock typically trades at an average daily volume of 50,000 shares, but today it is already traded 200,000 shares by midday. What does this tell you?

Interpreting the example:

  1. The increase in trading volume suggests that more people are buying and selling ABC company's shares today. This could be due to exciting news, like the launch of a groundbreaking gadget, or maybe the company's earnings report was better than expected. Increased trading volume often indicates enthusiasm and interest in the stock.
  2. With four times the usual trading volume, you might expect some price movement. If more people are buying (demand), the stock price could go up. Conversely, if more people are selling (supply), the price could drop. So, understanding the trading volume can help you anticipate potential price changes.
  3. High trading volume means more liquidity. In this example, if you decide to buy or sell shares of ABC company, it is more likely that you will find a willing counterparty quickly and without significantly affecting the stock's price.
  4. The increased trading volume could reflect the market's reaction to the latest developments related to the company. If it is positive news, the market sentiment might be optimistic, leading to more buying. If it is negative news, it could lead to more selling.

Remember that trading volume is just one piece of the puzzle. It should be considered alongside other indicators and research to make informed investment decisions. In this case, you would want to find out why the trading volume increased and whether it is likely to continue or not.


In essence, trading volume is like the heartbeat of the market, indicating its health and mood. It tells us if the market is buzzing with activity or if it is relatively quiet. Understanding these concepts is a valuable skill for investors and traders. Understanding the significance of trading volume in your investment journey can help you make more informed and strategic choices in the share market.
