What are ASM & GSM?

ASM: Additional Surveillance Measure

To enhance market integrity and safeguard investors’ interests, the Securities and Exchange Board of India (SEBI) and Exchanges have introduced various pre-emptive surveillance measures, including price band reductions, periodic call auctions, and transferring securities to the Trade for Trade segment.

In addition to these measures, SEBI and Exchanges, after joint surveillance meetings, have decided to implement Additional Surveillance Measures (ASM) on securities with surveillance concerns. These concerns are based on objective parameters such as price/volume variation, volatility, etc.
