ASM
Additional Surveillance Measure is an NSE/BSE framework that places selected securities under tighter market watch.
Exchanges apply ASM when price, volume, or client-concentration patterns look unusual.
ASM is a risk-control designation and does not by itself mean a company has broken the law.
Brokers and investors track published ASM lists for margin and trading implications.
Progressive short-term and long-term stage details are covered under ASM stages.
