Introduction

Stock market indices are used for tracking the performance of certain groups of stocks. With the help of these indices, one can get an idea about the overall trend in the stock market and how well the economy is thriving. Indices often serve as benchmarks for performance analysis. 

What are Nifty and Sensex?

Nifty, or Nifty 50, is a popular index of the National Stock Exchange, NSE, of India. This index includes the top 50 most liquid companies of India, across 13 sectors, and was launched in 1996. 

Sensex, or the S&P BSE Sensex, is the Nifty 50’s equivalent of the Bombay Stock Exchange, BSE. Unlike the Nifty 50, Sensex represents 30 of the largest companies listed on the BSE. This index was launched in 1986 and is one of the oldest stock indices in our country. 

Composition and Selection Criteria

Nifty

The Nifty is a collection of the top 50 largest stocks in the NSE. Its selection criteria include free-float market capitalization, liquidity, and sectoral representation. This index is reviewed semi-annually.

Sensex

The Sensex is a collection of the top 30 largest stocks in the BSE. Its selection criteria aren’t very different from that of the Nifty. Since the index focuses on a lesser number of companies, it is more concentrated. This index is reviewed regularly, although there is no fixed schedule.

Selection of companies

1. Market Capitalisation: The total market value of the company’s outstanding shares, or the market capitalisation plays a major role in the selection of companies for stock market indices. 

2. Liquidity: High liquidity of a stock enables easy access to buying and selling the shares of the company and hence is an important factor to be considered in selection. 

3. Diversification: Hence the indices attempt to represent the overall market or at least a certain tier of it, diversifying the list based on sectors and industries is an inevitable part of forming stock market indices. Unless of course, the index focuses on one particular sector, such as the bank Nifty which lists top trading banking companies. 

Weighting method

While calculating the indices, the shares have to be weighted to be included in the calculation. This weighting process can be done in four ways.

1. Price Weighted: Each stock contributes to the index in proportion to its price. 

2. Market Capitalisation Weighted: Each stock contributes in proportion to its market capitalisation.

3. Free-float Weighted: This case is similar to the market capitalisation except that only the publicly traded shares will be considered for calculation. 

4. Equal-weighted: The shares will be weighted equally irrespective of other metrics. 

Calculation Methods

Nifty and Sensex are calculated using the same method, which is the free-float market capitalization-weighted method. Under this method, only the shares that are traded publicly will be considered. The formula requires you to find the aggregate product of the price of the stock, the quantity of the stock, and the free-float factor of the stock. This product is then divided by a divisor which adjusts the index to a base value. 

Market Coverage

Nifty

Nifty includes 50 stocks in the list including mid-cap companies besides large-cap companies. This provides a wider market coverage and a broader view. 

Sensex

Sensex includes 30 stocks in the list and focuses on large-cap companies mostly. The index represents companies in the Indian market that are most financially stable.

Performance and Volatility

Nifty

Nifty focuses on a higher number of stocks and hence its performance is more reflective of the overall market compared to Sensex. Further, the volatility of the Nifty trading index is generally lower thanks to the diversification of the stocks across sectors.  

Sensex

Sensex meanwhile focuses on a lesser number of stocks in comparison to Nifty. This means that the performance is affected more by the top-tier companies. A less diverse collection here also increases the volatility of the Sensex trading index comparatively. 

Investment Strategies

For Conservative Investors

Nifty: Suitable, but then the exposure to the market is broader with the inclusion of some mid-cap companies. 

Sensex: This is more suitable for conservative investors, since most of the companies in this list are large-cap companies. 

For Aggressive Investors

Nifty: Here, this index is capable of offering more opportunities thanks to its broader market representation. The inclusion of mid-cap stocks will be advantageous here. 

Sensex: This can also be suitable for aggressive investors who are looking for large-cap companies that offer consistency in performance. 

Conclusion

Nifty and Sensex are primary indices in our stock market. They are both crucial and serve different purposes. While Nifty is known for its broader representation of the market with its 50 stocks, Sensex is known for its focus on top-tier stocks. While Nifty includes mid-cap companies, Sensex mostly has large-cap companies. However, when it comes to their significance to the Indian stock market they are both equally important. 

Knowing the differences between the two indices is essential to make the best use of them. Compatibility has to be checked based on the financial goals, risk appetite, and market outlook of the investors. Irrespective of which index you choose to engage with, both of them have insights to offer and opportunities to provide.
