How is NIFTY 50 Calculated?
NIFTY 50 uses a free-float market capitalisation weighted methodology:
- 1Take the current share price of each of the 50 companies
- 2Multiply by the free-float shares (shares available for public trading — excluding promoter holdings)
- 3This gives the free-float market cap of each company
- 4Add all 50 companies' free-float market caps
- 5Divide by the base market cap and multiply by 1,000
Companies with higher market cap (like Reliance, TCS, HDFC Bank) have more influence on the index movement than smaller companies.
