Calculation Method & Key Metrics
The Nifty Smallcap 100 index is calculated using the free-float market capitalisation method, which represents the actual tradable value of listed smallcap companies.
Market capitalisation is determined by multiplying a company’s share price by its total outstanding shares. The free-float market capitalisation then adjusts this figure by considering only the portion of shares available for public trading, excluding those held by promoters, governments, or strategic investors.
Index value formula: Index Value = (Total Free-Float Market Cap ÷ Base Market Cap) × Base Index Value
The base index value is 1,000, with 1 January 2004 as the base date.
For example, if a company’s market cap is ₹100 crore and its free-float factor is 0.6, the free-float market cap is ₹60 crore. The combined value of all constituents determines the Nifty Smallcap 100 share price, ensuring it reflects genuine market performance and liquidity.
