No changes in VAR/SPAN margin systems: NSE

The National Stock Exchange (NSE) has stated in a clarification that margins are computed and collected in both the cash market and F&O segments based on "Value at Risk" as prescribed.

No changes have been effected in the VAR/SPAN methodology and NSE continues to follow the same systems and procedures consistently," said the NSE in a circular that was put out after reports that the exchanges have been changing the VAR/SPAN margin systems over the last few months.
