Securities and Exchange Board of India (SEBI) and Exchanges in order to enhance market integrity and safeguard interest of investors, have been introducing various enhanced pre-emptive surveillance measures such as reduction in price band, periodic call auction and transfer of securities to Trade for Trade segment from time to time.

In continuation to various surveillance measures already implemented, SEBI and Exchanges, pursuant to discussions in joint surveillance meetings, have decided that along with the aforesaid measures there shall be Additional Surveillance Measures (ASM) on securities with surveillance concerns based on objective parameters viz.

  • High Low Variation
  • Client Concentration
  • Close to Close Price Variation
  • Market Capitalization
  • Volume Variation
  • Delivery Percentage
  • No. of Unique PANs
