What does a weather report tell you?
A weather report gives details about the present and forecasted weather, like temperature, rainfall, wind speed, and humidity. It allows you to plan your day and remain alert to any unexpected shifts in the weather.
You might be wondering why we’re talking about weather reports in a blog focused on the stock market index. The answer is that both serve a similar function. Just like a weather report provides an overview of the day’s weather conditions, a stock market index gives you an overall picture of market performance and indicates how the market is performing at any time. With a stocks app, you can easily track these indices and stay updated on market trends.
In this blog, we’ll break down what the stock market index is, the various types, how they are formed, and how they can aid in investing in stocks.
Meaning of Stock Market Index
A stock market index or stock market indices in a share market is a statistical measure designed to track how a selected group of stocks is performing. These stocks can belong to various industries or focus on a specific area of the market. The goal of the stocks index is to summarise the overall market performance or performance in a specific sector.
It provides insights into the health of the economy. When stock market indices increase, it signals that investors are generally positive about the market. On the other hand, a drop in these indices reflects a sense of negativity or lack of confidence among investors.
In India, the major stock exchanges are the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). The prominent market indices from these exchanges are the Sensex on the BSE and the Nifty 50 on the NSE. The history of stock market shows how indices like the Sensex and Nifty 50 have evolved over time.
Types of Stock Market Index
Benchmark Index
In the world of stock market indices, the Sensex and Nifty 50 are prominent examples. The Nifty 50 index represents the top 50 best-performing stocks, while the BSE Sensex includes the top 30. Known as benchmark indices, these are selected based on rigorous criteria to highlight the most reliable companies, serving as trusted indicators of overall market performance.
Sectoral Index
The BSE and NSE offer several stock indices tailored to specific sectors. For example, the Nifty IT index focuses on information technology companies, and the S&P BSE Healthcare index monitors companies in the healthcare sector. Investing in a sector index lets you invest in particular industries, providing targeted exposure.
Market Cap Index
Indices based on market capitalisation group companies according to their total market value. Examples include the Nifty Midcap 100 and the BSE Smallcap. These indices provide insights into different segments of the market based on company size, offering a unique view of market dynamics.
Other Types of Index
There are various stock indices you can consider, such as the NSE 100, S&P BSE 100, and S&P BSE 500. These other indices include more stocks than the Sensex or Nifty 50 index stocks. While some stocks in these indices may be riskier, you might prefer investments with lower risk.
Investment portfolios cannot cater to every individual need. It’s essential to focus and invest in sectors where you are comfortable. These examples are just the beginning. Depending on your stock market trading strategy, you can track different stock indices that fit your approach.
How are Stock Market Indices Calculated?
A stock market index is made by selecting stocks according to factors like market capitalisation, company size, or industry sector. To find the value of the index, you cannot just sum up the stock prices since they differ. Instead, each stock is assigned a weight based on its market price or market capitalisation to determine how much it influences the index. To effectively track the indices and stay updated on market movements, you can use the HDFC Sky stock market app.
There are two main methods for weighting stocks:
- Market Capitalisation Weightage: This method gives each stock a weight according to its market capitalisation, which is calculated by multiplying the total number of shares by the share price. Stocks with a higher market capitalisation have a greater impact on the index. In India, many indices use free-float market capitalisation, considering only shares that are publicly traded and excluding those held by promoters or the government.
- Price Weightage: This method assigns more weight to stocks with higher prices, so they affect the index value more than lower-priced stocks.
To keep the index accurate and up-to-date, the list of stocks is adjusted regularly. Stocks may be removed if their market capitalisation decreases or if they no longer meet the inclusion requirements, while new stocks are added based on their market performance.
Conclusion
Stock market index plays a vital role in helping us gauge market performance. From broad indices like the Sensex to more targeted ones like the Nifty IT, these market indices provide insights into how the market or specific sectors are performing. This can be valuable in making sound investment decisions.
By monitoring stock market indices, you can recognise trends and decide if it’s an appropriate moment to buy or sell stocks. Whether you’re new to investing or experienced, understanding these indices can improve your decision-making when you invest in the stock market.
