What Is Nifty in the Share Market?

Shares with Differential Voting Rights (DVRs) are accepted. Besides scheduled reviews, mergers, delistings, or suspensions may lead to changes as well.

How is Nifty Calculated? 

Indices for Nifty 50 are computed through a float-adjusted as well as market capitalisation-weighted method. The level of the index showcases the aggregate of the market value of shares present in it for a certain duration. This base duration for Nifty is November 3, 1995. The index’s base value is 1,000, and its base capital is ₹2.06 trillion. The formula to calculate the index’s value is as follows: 

Index Level = (Current Free-Float Market Cap ÷ Base Market Cap) × 1000 

Where: 

Current Free-Float Market Cap = sum of (price × free-float shares) for all 50 companies 

Base Market Cap = market cap on Nov 3 1995 

1000 = base index value 

This method ensures that changes due to stock splits, corporate actions, or rebalancing are adjusted through appropriate index maintenance mechanisms.
