Impact Assessment
Traders and investors holding or planning to take positions in the following 6 securities will face higher margin requirements:
| Sr. No. | Symbol | Security Name | ISIN |
|---|---|---|---|
| 1 | ANNAPURNA | Annapurna Swadisht Limited | INE0MGM01017 |
| 2 | ATCENERGY | ATC Energies System Limited | INE0V0Q01019 |
| 3 | BETA | Beta Drugs Limited | INE351Y01019 |
| 4 | JEYYAM | Jeyyam Global Foods Limited | INE0RXB01022 |
| 5 | PRIMO | Primo Chemicals Limited | INE607A01022 |
| 6 | RUCHINFRA | Ruchi Infrastructure Limited | INE413B01023 |
The increased margin requirement of at least 50% under Stage I will reduce leverage available to traders, potentially dampening trading volumes and liquidity in these securities. RUCHINFRA is subject to ST-ASM criteria at BSE as well, indicating cross-exchange surveillance concern.
