Impact Assessment

Securities placed under the Additional Measure framework are subject to enhanced surveillance and may face trading restrictions such as reduced price bands or additional margin requirements. The measure is designed to curb unusual price movements and protect market integrity. Stocks newly added (Annexure I) will face tighter trading conditions from May 11, 2026, while those exiting (Annexure II) will revert to normal trading parameters. Traders and investors holding positions in affected securities should review the annexures to assess impact on their portfolios.

Impact Justification

Routine periodic review under the Additional Measure (AMS) surveillance framework affecting specific securities identified for unusual price movement. Impact is medium as it restricts trading conditions for affected securities but is a standard regulatory mechanism.
