3. BSE/NSE trading groups

On BSE, shares are also classified into categories such as A, B, T, XT, Z and others, based on factors such as trading/liquidity and compliance.

One important point first: BSE and NSE do not use exactly the same “A/B/T/Z” group system. These labels are mainly associated with BSE stock classifications. NSE has its own series/market-segment classifications.

BSE

A: Generally actively traded, established companies

B:Other listed/traded companies

T:Trade-to-Trade settlemen

XT:Special surveillance/trade-to-trade category

Z:Non-compliance-related classification

NSE

EQ: Normal equity market series

BE: Trade-to-Trade settlement

BZ: Trade-to-Trade/security under surveillance-type classification

SM: SME platform

ST: SME securities with specific trading framework

If your main strategy is swing trading or buying stocks for delivery, don't automatically avoid B/T or other special categories—but check why the stock has been placed there.

If you are doing intraday trading, focus primarily on stocks with normal trading status, good liquidity and sufficient volume, rather than simply looking at A Group.
