What is Additional Surveillance Measures (ASM)?
SEBI has introduced various surveillance measures to safeguard the interests of investors and enhance market transparency, including reducing price bands, conducting periodic call auctions and transferring securities to the Trade-to-Trade (T2T) segment as required.

It is enforced based on objective parameters such as price (high-low) variations, volume variations, volatility, etc. Based on these parameters, securities are shortlisted and reviewed under different frameworks including

Long-term ASM - 4 stages
