Sensex

The BSE SENSEX, also written Sensex, is a stock market index of 30 large, established companies listed on the BSE (formerly the Bombay Stock Exchange). It is widely treated as the main benchmark for the Indian equity market.

The index is calculated on a free-float market capitalisation basis, which counts only the shares available for public trading. Its constituents span sectors such as banking, information technology, consumer goods, energy, automobiles and pharmaceuticals. Asia Index owns and operates the index, and its composition is reviewed and rebalanced periodically.

The Sensex has been published since 1 January 1986, with a base value of 100 on 1 April 1979. Analyst Deepak Mohoni coined the name in 1989 as a blend of “sensitive” and “index”. It first crossed 1,000 on 25 July 1990 and closed above 10,000 on 7 February 2006. It crossed 50,000 on 21 January 2021 and 70,000 on 11 December 2023, according to Wikipedia.

It is in the news on 11 November 2026, when it rose more than 1,100 points in early trade as crude oil prices eased and sentiment towards IT stocks firmed.
