What Are Group A Stocks?
Group A stocks are some of the most actively traded with highly liquid shares on the exchange. Consistently high levels of trading activity and high standards of regulation and compliance are observed in these stocks, and are set by the exchange. Trades occurring in this category are settled through the normal rolling settlement mechanism, and as such, are conducive to the normal rolling of trading activity.

Hierarchy of Selection of Companies in Group A
-
Companies that have been ranked among the top 200 (based on the Group A scoring methodology) for the last 3 consecutive quarters are first included in Group A.
-
Companies that were in the top 200 for at least the previous two quarters are taken into consideration and added if this list still contains fewer companies than the intended Group A universe.
-
Companies that are currently rated in the top 200 in the most recent quarter are additionally included if the total falls short of the goal count after applying the aforementioned two filters.
-
Even if they momentarily drop out of the top 200 by rank, S&P BSE 500 companies that are currently categorised in Group A will typically stay in this group until they violate liquidity/compliance requirements during surveillance inspections.
*Please note that the number of companies in group A may vary from the number mentioned above.
Other Groups in BSE
Apart from Group A, there are groups in BSE, including T, Z, S and B categories, identified based on liquidity compliance and trading rules. Group T stocks are settled on a trade-to-trade basis with intraday trading not permitted. Group Z is for companies that are failing to comply or investor grievance norms. Group S includes small and mid-sized firms, which are less liquid and have greater volatility. Stocks that do not meet these requirements are considered under Group B, which experience regular rolling settlement with average trading volumes.
