Composition and Calculation of the S&P Nifty

The top 50 companies that meet the eligibility criteria are included in the index.
The calculation of the S&P Nifty Index is based on the free-float market capitalization weighted methodology. This means that the weightage of each constituent in the index is determined by its market capitalization, adjusted for the proportion of shares that are available for trading in the market (known as the free-float factor). The index is calculated in real-time during market hours and is disseminated every 15 seconds.
The S&P Nifty Index is widely regarded as a reliable indicator of the Indian stock market’s performance. It provides investors with a snapshot of the top 50 companies and their collective performance, allowing them to gauge the overall market sentiment and trends.
