History of BSE Sensex

How is BSE Sensex Calculated?
The BSE Sensex is calculated using the free-float market capitalization method. This method considers only the shares available for trading, excluding locked-in shares held by promoters and institutional investors. The formula used for calculation is:
Sensex = (Sum of Free-Float Market Capitalization of all 30 companies) / (Base Market Capitalization) × Base Value
The base year for the BSE Sensex is 1978-79, with a base value of 100. This means that any changes in the index reflect the percentage change in the market capitalization of the constituent companies compared to the base year.
