How Companies Enter the Sensex Index

Eligibility Requirements : 

To be included in the Sensex, a company must fulfill certain key criteria. The company must possess a substantial free-float market capitalization, its shares must undergo regular trading, and it must serve as a strong representative of its respective sector.

Free-Float Market Capitalization Assessment : 

The first step involves assessing the company's free-float market capitalization. This calculation is based solely on those shares that are available to the general investing public.

• Formula : Free-Float Market Cap = Share Price × Publicly Available Shares

• Example : If a company's share price is Rs. 1,000 and 100 crore shares are publicly available, its free-float market capitalization would be Rs. 1 lakh crore.

Liquidity Check : 

There must be sufficient buying and selling activity in the company's shares. Companies with higher trading volumes are given priority, as this indicates active investor participation.

Sector Representation Review : 

A balance across various sectors is maintained within the Sensex. If a particular key sector is underrepresented, eligible companies from that sector may be considered for inclusion.

Index Committee Evaluation : 

A committee comprising representatives from S&P Dow Jones Indices and the BSE reviews all eligible companies. Based on this review, a decision is made regarding which companies qualify for inclusion in the Sensex.

Periodic Rebalancing : 

The Sensex undergoes periodic reviews. If a new company demonstrates stronger eligibility criteria than an existing constituent, it may be included in the index, while the incumbent company may be removed.
