Understanding the Sensex
What Constitutes the Sensex?
The Sensex comprises 30 well-established and financially sound companies across various sectors, including finance, energy, technology, and consumer goods. These companies are selected based on their market capitalization, liquidity, and representation of the Indian economy. The index is free-float market-weighted, meaning that only the shares available for trading are considered in its calculation.

The Sensex is calculated using the free-float market capitalization method, which considers the market value of the shares that are readily available for trading. This approach ensures that the index accurately reflects the market movements and investor sentiment. The base year for the Sensex is 1978–79, with a base value of 100.
