Leading index provider Asia Index today announced changes to the methodology of S&P BSE MidCap Select Index and S&P BSE SmallCap Select Index.
The indices will now have market capitalisation buffer rule for their current constituents along with liquidity buffer rule, according to an announcement on the BSE website.
At present, there is no such criteria in these indices.
The changes will be effective with the September 2016 rebalance, Asia Index said.
As per the new methodology, current constituents of the S&P BSE MidCap Select Index with a market capitalisation of at least Rs 1,600 crore and annualised traded value of at least Rs 800 crore will remain eligible for index inclusion provided they meet the other eligibility criteria.
For the S&P BSE SmallCap Select Index, the market capitalisation has been set at Rs 480 crore and the constituents need to have an annualised traded value of at least Rs 240 crore for being eligible.
Current constituents of both the indices with a turnover ratio of 16 per cent will also remain eligible for inclusions.
