Also, NSE Indices has revised the eligibility criteria for inclusion in Nifty 500, Nifty 100 and Nifty Midcap 150 indices.

Under the new criteria for Nifty 500,companies should rank within top 800 - based on both average daily turnover and average daily full market capitalisation on the basis of previous six months' data.

"The investible weight factor of stock should be at least 0.10 (10 per cent free float) or 6 month average free float market capitalization of the stock should be at least 25 per cent of the 6 month average full market valuation of the existing smallest index constituent (prior to index review) by full market capitalization in Nifty 500 as of the cut-off date for inclusion in the index," the NSE Indices said.
