What is the short-term ASM list?

The NSE and BSE stocks under short-term ASM (ST-ASM): Stage I after a sharp price move over 5 or 15 trading days with concentrated trading, and Stage II for a further move soon after. Stage I carries a margin of at least 50% and Stage II 100%.

How long does a stock stay on short-term ASM?

Each stage is held at least 5 or 15 trading days and reviewed from the 6th or 16th trading day: a stock that no longer meets the criteria on the review date leaves. A stock that moves to long-term ASM leaves short-term ASM.

How often is the short-term ASM list updated?

The exchanges publish their ASM lists every trading day. This page is rewritten every weekday night after the day's lists are out; the date above the list says which day it shows.

Is being on the ASM list an adverse action against the company?

No. ASM shortlisting is a market surveillance measure based on price and trading patterns. It is not an adverse action against the company and not a judgement about its business.
