Everything you should know about Nifty 50

What is Nifty 50?

The NIFTY 50 is an index of the top 50 companies by market capitalization, which are listed on the National Stock Exchange (NSE). The National Stock Exchange of India (NSE) introduced the NIFTY fifty index on April 22, 1996. The index comprises the top 50 liquid large-cap stocks from 13 sectors of the economy which are traded on the NSE.

It is a popular indicator used by investors to measure the stock market's performance. The other major index is the Sensex, comprising 30 stocks, managed by the Bombay Stock Exchange (BSE).

 

 Although the NSE has more than 1,300 stocks, "the market was up today" usually implies that the NIFTY 50 index rose in value. This shows that the average performance of the 50 stocks was positive. Foreign investors often view the NIFTY movement as their main reference point when studying the Indian markets, and in many cases, their initial investments in India are in NIFTY stocks.

The NIFTY 50 is a good indication of the top-performing stocks, with many of them being the cream of the crop regarding balance sheets, growth numbers, and global reach. Companies like Infosys, Reliance Industries, HDFC Bank, ITC, and Asian Paints, are all part of the elite list of NIFTY 50 stocks, having met the criteria of liquidity, F&O availability, and the six-month listing requirement. The list is revised every six months to ensure the index remains dynamic and responsive to the changing market. This is done so that financial products and baskets built around NIFTY stocks can have time to adjust their portfolios accordingly.

The stocks ousted from the NIFTY have experienced a sharp drop in prices, while the stocks added to the NIFTY have seen an upward surge. This demonstrates that the NIFTY is an ever-evolving and dynamic index.

 For example, NIFTY has seen significant changes in the past ten years. Out of the 50 stocks that were part of the index in 2010, only 30 remain today. This equates to 40% of the index being replaced in a decade.

 How is Nifty calculated?

The Nifty 50 index is calculated using a free-float methodology, meaning that only shares readily available for trading in the market are used in the calculation. This makes the index more representative of the actual market conditions.

For example, if a company has 100 shares outstanding and its current share price is Rs 20, then the market capitalization of this company will be Rs 2000.

 Now the Nifty 50 index value will be calculated as follows:

•       Index value = 2000/(Base Market Cap x 1000)

 •       Base Market cap = 2000/1000 = 2

 •       Therefore, Nifty 50 Index value = 2000/(2 x 1000) = 1.00

Now let's find out the market cap and free-float market capitalization:

Suppose Company A has 200 million outstanding shares with a current price of Rs 10.

•   Market cap = 200 million x 10 = 2 billion

•   Free-float market capitalization = 2 billion x IWF (Index Weight Factor) = 2 billion x 0.45 = 900 million

•   Nifty 50 = 900 million / (2 billion x 1000) = 0.45

Therefore, the index value of Company A is 0.45.
