ST-ASM · ASM 1What does ST-ASM · ASM 1 mean?
NSE · Short Term Additional Surveillance Measure (ASM 1)ST-ASM catches short bursts: a beta-adjusted close-to-close move beyond ±25% in 5 trading days (or ±40% in 15) combined with concentrated trading — or a 75%+ monthly range with fewer than 100–200 unique traders. Practical meaning: margins jump to 50–100% for a few weeks to cool a spike; it either lapses quickly or escalates into LT-ASM if the move sustains.Criteria: Short-term (5 / 15 / 30-day) price-volume abnormality — high-low and close-to-close price variation over the window. Adds 100% margin and a 5% (then 2%) price band.Exchange notice · 2026-09-07
