Compliance Requirements

- Securities under ST-ASM Stage I are subject to applicable additional margin requirements as per SEBI/NSE guidelines
- Securities under ST-ASM Stage II face stricter surveillance conditions including enhanced margins and trade-to-trade settlement
- IBULLSLTD, IRMENERGY, and VIDYAWIRES, while exiting STASM, are now under LTASM and remain subject to long-term surveillance restrictions
- CLASSICEIL and TROM transition to ESM (Enhanced Surveillance Measure), which carries its own set of trading restrictions
Important Dates
- Effective Date: May 06, 2026 — All additions, escalations, de-escalations, and exclusions take effect
- Circular Date: May 05, 2026
Impact Assessment
High impact on the 8 newly ASM Stage I securities (BCPL, CALSOFT, CEMPRO, MWL, OMAXAUTO, RICHA, SAIFL, STYLEBAAZA): investors will face higher margin requirements, potential trade-to-trade settlement constraints, and reduced liquidity, often leading to short-term price volatility.
Heightened impact on WEBELSOLAR: Escalation from Stage I to Stage II signals continued regulatory concern; Stage II typically involves stricter margin calls and enhanced monitoring, which may further suppress price and liquidity.
Positive signal for excluded securities (ADFFOODS, ARISTO, AYMSYNTEX, ELECON): Removal from ASM framework suggests improved surveillance metrics; may reduce trading friction and attract broader investor participation.
Neutral-to-cautious for LTASM/ESM transitions (IBULLSLTD, IRMENERGY, VIDYAWIRES, CLASSICEIL, TROM): These securities exit STASM but remain under alternative surveillance regimes, so restrictions are not fully lifted.
Impact Justification
Directly affects trading conditions for 18 securities across multiple sectors; ST-ASM inclusion imposes additional margin requirements and trade restrictions, significantly impacting investor strategy and liquidity for the named stocks.
