The first headline most investors see after the market rises sharply or falls unexpectedly is about the Sensex or the Nifty. While many new investors know the names of these two benchmark indices, they have little idea of what these represent or why they both exist.
The broad purpose of the Sensex and Nifty is the same, as both measure market performance. However, they differ in terms of the stock exchanges they represent, the number of companies they track, and the construction methodology. In this blog, we have explained the key differences between the benchmark indices so that you can interpret market movements better.
The two benchmark indices of India
A stock market index is a basket of stocks representing the performance of a particular segment of the market. Investors use the benchmark indices to understand the overall direction of the market instead of tracking thousands of listed companies individually.
What is Sensex?
The Sensex is the benchmark index of the Bombay Stock Exchange (BSE), the oldest stock exchange in India. It was introduced in 1986 and consists of 30 large-cap companies from different sectors. The listed companies are reviewed periodically, so that the index continues to represent the leading businesses of the country.
What is Nifty?
The Nifty 50 is the benchmark index of the National Stock Exchange (NSE). Launched in 1996, it tracks 50 large-cap companies listed on the exchange across multiple sectors of the economy. Today, the Nifty serves as the benchmark for numerous mutual funds, ETFs, derivatives contracts, and institutional portfolios. Investors, analysts, and fund managers use this index to gauge the overall health of the Indian equity market.
Sensex vs Nifty: Key differences
Both indices move in response to market conditions, but there are several differences between them that investors should understand.
The stock exchange
The stock exchange each index represents defines the key difference. The Sensex tracks companies listed on the Bombay Stock Exchange, while the Nifty is composed of companies listed on the NSE.
Number of constituent companies
Another difference lies in the number of companies listed under each index. The Sensex has 30 companies under it, while the Nifty is composed of 50 companies. This gives it a slightly broader coverage.
Although these differences exist, both the indices use the free-float market capitalisation methodology. This means companies with larger freely tradable market values have a greater influence on index movements. As a number of leading companies are included in both indices, they often move in the same direction. However, the magnitudes of their movements may slightly vary.
Which index should investors follow?
For investors learning the share market basics for beginners, it’s important to understand both indices rather than choosing one over the other. Many mutual funds, ETFs, and investment products use either the Sensex or the Nifty as their benchmark.
That’s why you must be familiar with both, which helps in evaluating fund performance and understanding market trends.
Conclusion
The Sensex and the Nifty represent how the largest listed companies in India perform. Investors gain a quick insight into the equity market of the country through these benchmark indices.
