The Nifty Top 10 Equal Weight Index aims to track the performance of the top 10 companies selected based on their free-float market capitalization from the Nifty 50 index. Unlike the Nifty 50, which weights companies based on their market capitalization, all stocks in the new index have an equal weight of 10%. This provides a more equal representation of the top companies and potentially reduces the influence of large-cap stocks.
