Formula:
Index market capitalization / Gross earnings
where
Index market capitalization of the Index constituents is the sum total of the outstanding equity shares or units considered for index computation multiplied by the close price of each index constituent adjusted for factors such as free-float, capping factor etc. depending upon the index methodology; and
The earnings (including profits and losses) reported by each index constituent in trailing 4 quarters (consolidated financials) are cumulated and adjusted for factors such as free-float, capping factor etc. depending upon the index methodology to arrive at the gross earnings. In case, consolidated financials are not available, standalone financials for trailing 4 quarters will be considered.
In case overall earnings value (of all constituents put together) for any index is negative, PE ratio for such indices are not computed and published by NSE Indices. PE ratio will be published again from the date when overall earnings value is positive.
