NSE rebranded all its indices to include 'Nifty' in their names as against the name 'CNX' used currently, in a bid to capitalise on the brand name of its benchmark index. NSE's flagship 'CNX Nifty' index has now become 'Nifty 50', Nifty Junior has become 'Nifty Next 50', CNX IT has become 'Nifty IT', among others, the exchange MD & CEO Chitra Ramkrishna said. There are 16 constituents that continue to be part of Nifty 50 since its inception.
