NSE’s Graded (GSM), Additional (ASM) and Enhanced (ESM) Surveillance framework, plus the promoter-encumbrance flag, across our whole covered universe. Current status is free to browse. Stage-change history and promoter-pledge trends need a free account.
NSE’s GSM, ASM, and ESM are special monitoring frameworks used by exchanges and SEBI to curb excessive speculation, alert investors, and protect market integrity.
ASM
Additional Surveillance Measure
Watches trading behaviour — price-volume variation and high volatility. Triggered by unusual volume spikes or client concentration, and brings higher margin requirements and narrowed price bands.
GSM
Graded Surveillance Measure
Watches a stock's fundamentals against its price rise. Triggered by weak financials, low net worth, or an abnormal P/E, and moves the stock to Trade-for-Trade (T2T) with an Additional Surveillance Deposit (ASD) required.
ESM
Enhanced Surveillance Measure
Focused on micro-cap and small-cap companies prone to manipulation. Triggered by high volatility in lower-market-cap names, and brings strict T2T settlement with limited weekly trading sessions.
What happens when a stock is placed under ASM/GSM/ESM?
- Price bands are reduced or tightened.
- Margin requirements rise, or an Additional Surveillance Deposit (ASD) is required.
- The stock moves to Trade-for-Trade (T2T) settlement — no intraday trading, delivery-only.
- Trading frequency can be reduced in the more severe stages — e.g. weekly instead of daily sessions under ESM.
- Corporate actions (bonus issues, rights issues) can be restricted or face additional scrutiny while a stock is under these frameworks.
