How Nifty is calculated?

Nifty is based on market capitalisation, it basically a market capitalization weighted index. It involves total market capitalization of company weighted by its effect over the index. So, the firm with higher market capitalisation will make more difference to the index as compared to a smaller market cap company.

One must know a few things before calculation of Nifty50:-

  • 1995 is taken as base year
  • Base Value is 1000
  • Nifty50 takes into consideration 50 stocks of 24 various sectors that are actively traded in the market

Let’s understand the calculation

  • Market Capitalization = Shares outstanding * Market Price Per Share
  • Free Float Market Capitalization = Shares outstanding * Price * IWF (Investible Weight Factor)
  • Index Value = Current Market Value / Base Market Capital * Base Index Value (1000)

Nifty comprises of 3 stocks A, B and C

Assume A has 1,000 shares. Promoters hold 200 and the rest 800 are available for active trading and hence are free-floating. B has 2,000 shares. Its promoters hold 1000. Rest 1000 are free-floating C has 3000 shares, its promoters hold 1500 shares and 1500 are available for active trading.

Say price of A is Rs.10 and that of B is Rs.20, Price of C is 35

A’s total market capitalization = 1,000 x Rs.10 = Rs.10,000

Free-float market cap = 800 x Rs.10 = Rs.8,000.

B’s total market cap = 2,000 x Rs.20 = Rs.40,000.

B’s free-float market cap = 1000 x Rs.20 = Rs.20,000

C’s total market cap = 3000 x Rs.35 = Rs.105,000

C’s free-float market cap = 1500 x Rs.35 = Rs.52500

Total free float market cap of A,B &C = Rs.(8,000+20,000+52500)= Rs.80,500

Assume Market Cap during 1995 was Rs.5,000

Then, NIFTY = 80500*1000/5,000 = 16,100
