Impact Assessment
Newly Added to ESM Stage I (effective May 15, 2026 for segment shift):
| Symbol | Security Name | ISIN |
|---|---|---|
| BSHSL | Bombay Super Hybrid Seeds Limited | INE032Z01020 |
| CHEMFAB | Chemfab Alkalis Limited | INE783X01023 |
| LATTEYS | Latteys Industries Limited | INE262Z01023 |
| NIRAJ | Niraj Cement Structurals Limited | INE368I01016 |
| PRIMECAB | Prime Cable Industries Limited | INE0CQA01020 |
Moved to ESM Stage II (stricter restrictions):
| Symbol | Security Name | ISIN |
|---|---|---|
| EMPOWER | Empower India Limited | INE507F01023 |
The imposition of 100% margin and Trade-for-Trade restrictions will significantly reduce liquidity and increase the cost of trading in these securities. Stage II placement of EMPOWER with a 2% price band under Periodic Call Auction further restricts price discovery and intraday trading. NSE emphasizes these measures are purely for market surveillance purposes and should not be construed as adverse action against the listed companies.
Impact Justification
Direct trading restrictions imposed on 6 securities including 100% margin requirement and segment shift from Rolling Settlement to Trade-for-Trade, significantly affecting trading conditions for these stocks.
