What is Additional Surveillance Measure (ASM)? All you need to know

The Additional Surveillance Measure (ASM) is implemented by SEBI and stock exchanges to monitor stocks with unusual trading patterns, ensuring market transparency and stability.

ASM serves as a precautionary tool to alert investors, though it does not imply wrongdoing by the company.
