How Nifty is calculated?

• The formula for calculating the Nifty= (Sum of free flow market cap of 50 benchmark stocks)*Index Factor

• Index Factor = 1000/Market Cap Value in 1995.

Where, 1000 is the Index value during 1995.

• Market Capitalization is the total worth of the outstanding (issued ) shares of the company it represents the total worth of the company

• Market Capitalization = Share Price * Total Shares

• Example :• ICICI bank issued 1000 shares out of

which 200 shares are with govt,500 shares by director of the company and remaining 300 shares are available in the open market for trading & market price is Rs.10

• Here total market cap – 1000*10=10,000.• Free float market cap – 300*10=3000.

In calculation of nifty (same method is used)

Sum up all 50 shares floated market cap*1000/market cap in 1995.

Let ICICI, Bharti Airtel are having free float market cap of 3000, 7000

According to formula

(7000+3000)*1000/market cap in 1995

Assume that market capitalization in 1995 be 20000

Then,

(10,000)1000/20000=500

Index value is 500.
