Stock classification is the process of grouping stocks for ease of understanding. In India both BSE (Bombay Stock Exchange) and NSE (National Stock Exchange) classifies stocks. More or less the classification of stocks is similar on both platforms.
This stock classification was done to handle the stocks based on trading characteristics of Indian shares on the exchange platform and are known as grades. Mainly there are seven grades of stocks namely, A, B, T, S, TS & Z. All other stocks which fail the characteristics of any one of these grades were kept in others. These grades are scores of stocks on the basis of their size, liquidity and exchange compliance.
The main characteristics of various stock classification are as follows:
1. A Group – highly liquid
- The stocks fall in the category of A ‘Group’ are the most liquid counters among all the stocks listed on the BSE.
- The market rates group A stocks as excellent in all aspects and they also show comparatively high traded volume during trading.
- Settlement of group A stocks trades is done under the normal rolling settlement process.
2. T Group – trade-to-trade
- The stocks fall under T group are considered as Trade-to-trade settlement system of the exchange.
- Each trade in this group is seen as a separate transaction and there is no netting-out of trades as in the rolling system
- The traders who buy shares of this category or sell the script of this group, have to pay the amount or deliver the shares by T+2 days.
- For example, you bought 100 shares of T Group and sold another 100 shares on the same day. Then, the shares you have bought, you will have to pay the price of those shares in two days. And for the shares you have sold, you will have to make the delivery of shares by T+2 days, so that Exchange can make the settlement on time.
- Stocks of T group are regularly moved in and out of trade-to-trade settlement depending on the speculative interest that governs them.
