The National Stock Exchange of India updates the list of securities under the Enhanced Surveillance Measure framework. Securities in Annexure I move to the Trade-for-Trade segment and require a 100 percent margin starting October 6, 2026. Securities in Annexure II exit the framework. Securities that move to Stage II enter the Trade-for-Trade segment with a 2 percent price band under Periodic Call Auction starting October 5, 2026. The exchange reinstates the original price band for securities that exit the framework, unless other surveillance measures apply. This action results from market surveillance and does not indicate adverse action against the companies.
What you must do
- Apply a minimum 100 percent margin on open positions as of October 5, 2026, and new positions from October 6, 2026, for securities in Annexure I.
- Shift securities qualifying under ESM from Rolling Settlement segment to Trade-for-Trade segment effective October 6, 2026.
