The circular specifies securities moving into ST-ASM Stage I and Stage II, securities transitioning between stages, and securities being excluded from the ASM framework.

Impact Assessment
Trading Impact: Traders holding positions in the affected securities will face significantly higher margin requirements, which may force position closures or require additional capital deployment. The 50% minimum margin requirement represents a substantial increase from normal margin levels.
Liquidity Impact: Securities under ST-ASM typically experience reduced trading activity due to higher capital requirements, potentially leading to wider bid-ask spreads and lower volumes.
Risk Mitigation: The surveillance measure aims to curb excessive speculation and price manipulation in securities showing abnormal market behavior, protecting overall market integrity.
Positive Development: Three securities (RICOAUTO, S&SPOWER, VLSFINANCE) are being excluded from ASM framework, indicating improved market behavior and reduced surveillance concerns for these stocks.
Impact Justification
Increased margin requirements significantly impact traders holding positions in affected securities; affects multiple stocks with staged surveillance implementation
