The CNX 200 Index is designed to reflect the behaviour and performance of the top 200 companies measured by free float market capitalization. The index comprises of 200 such companies that are listed on the National Stock Exchange (NSE).


The CNX 200 Index is computed using free float market capitalization method with a base date of January 1, 2004 indexed to a base value of 1000, wherein the level of the index reflects the total free float market value of all the companies in the index relative to particular base market capitalization value. The method also takes into account constituent changes in the index and importantly corporate actions such as stock splits, right issue, new issue of shares etc. without affecting the index value.
