Once chosen, the presence of each company within the index is periodically reviewed to maintain a representative structure.

Sectoral Influence and Distribution

The BSE Sensex incorporates representation from various sectors, with financial services, energy, manufacturing, and information technology among the most prominent.

Global Recognition and Market Positioning

Though deeply rooted in the Indian financial market, the BSE Sensex has achieved recognition for its longevity and consistency.

The index supports cross-sectoral insight, offering reference points for understanding how industries interact with macroeconomic developments. Its international reputation is based on stability and the history of tracked performance rather than comparative positioning.
