How is the BSE Index Calculated?

BSE generally modifies the share composition of Sensex constantly to reflect the current condition of the stock market. The index is calculated based on the weighted methodology of market capitalisation. This calculation method was, however, reformed in 2003 and now includes a free-float capitalisation method.

The method is an alternative for the market-capitalisation method. Here, instead of the firm’s outstanding shares, the shares available for sale are used for calculating the index. It doesn’t include restricted stocks that are not for sale. For getting free-float capitalisation, the market capitalisation of a firm needs to be multiplied with the free-float factor. The free-float factor is a ratio of floated shares and outstanding shares. This free-float capitalisation method states that the index level demonstrates the free-float value of all the 30 companies at all times under the Sensex, in relative to the base period.
