What is Graded Surveillance Measure (GSM)?


SEBI has introduced various surveillance measures to safeguard the interests of investors and enhance market transparency, including reducing price bands, periodic call auctions, and the transfer of securities to the Trade-to-Trade (T2T) segment as required. 

The Graded Surveillance Measures (GSM) are used to monitor unrealistic price changes in stocks that do not align with a company's financial health and fundamentals like earnings, book value, etc. Securities are marked under GSM to alert investors to be cautious and diligent while dealing in them.
