How is NIFTY 50 Calculated?

Before we begin to understand how NIFTY 50 is calculated, there are a couple of things that you need to keep in mind.

• Free float market capitalisation is the market capitalisation calculated for all the shares which are publicly available for trading. It is important to remember that free float market capitalisation does not take those shares into account which are held by promoters, government, employee welfare funds, or any corporate entity. The proportion of shares which are held by the general public and are available for trading is represented by a ratio known as Investible Weight Factor (IWF).
• The base year is 1995 and the base value is 1,000. The base market capital is the market capitalisation of the company in the year 1995.
• NIFTY 50 index is calculated for the 50 stocks which are actively traded on the NSE.
• Base market capital is the aggregate market capitalisation of each stock in the index during the base period.

Therefore,

Free float market capitalisation = (Shares outstanding) x (Price) x (IWF)

Index Value = (Current Market Value)/(Base Market Capital) x (Base Index Value)

To understand this better, let us consider an example. For the sake of simplicity, let us assume that NIFTY comprises only two companies - X and Y.

Company X has a total of 1,000 shares of which, 300 are held by promoters while the remaining 700 are held by the general public, and are available for trading. As for the Company B, it has a total of 1,500 shares of which 1,000 are available for active trading and the remaining 500 are with promoters, governments and corporate entities.

The share price of Company X is Rs.20 and the share price of Company Y is Rs.30. The base market value of the two companies is Rs.6,000.

Hence,

X’s free float market capitalisation = 700 x 20 = Rs.14,000

Y’s free float market capitalisation = 1,000 x 30 = Rs. 30,000

Total free float market cap of the two companies = Rs.44,000. Therefore, NIFTY = (44,000)/(6,000) x 1,000 = 7,333.3
