How Sensex is calculated?

Initially, Sensex used the weighted market capitalisation methodology and later on shifted to ‘Free Float market capitalization‘ methodology on September 1, 2003. Free-float is that percentage of total shares that is issued by the company that are readily available for trading in the market. It excludes shares held by promoters, government etc. Market capitalisation represents the valuation of a company. It is determined by multiplying the price of their stocks with the number of shares issued by that company. Market capitalisation = price * quantity

Free-float market capitalisation = market capitalisation * free float factor

Steps to calculate SENSEX

  1. Firstly, the 30 companies are selected on the basis of various quantitative and qualitative criteria including total market capitalisation, free float market capitalisation, sectoral representation etc. These companies will be from all major sectors including Banking, IT, FMCG.
  2. Then the market capitalisation and free-float market capitalisation of each of the 30 companies is calculated
  3. After multiplying the market capitalization with the free-float factor, we get free-float market capitalization.
  4. The free-float market capitalisation of the 30 companies is added all together and that is the total free-float market capitalisation.
  5. The formulae for calculating Sensex: Sensex = (total free-float market capitalisation/ Base market capitalisation) * Base index value.
