BSE would move 24 stocks to the trade-for-trade segment or the 'T' Group while NSE would transfer 13 scrips to this category with effect from September 16, 2013, the stock exchanges said in separate notifications.
Some other stocks which would be shifted to the 'T' Group segment on both the bourses are -- Austral Coke & Projects, BSEL Infrastructure Realty, Megasoft and Uttam Sugar Mills.
Besides, BSE would also be shifting Axis Capital Markets and Nimbus Projects to the 'T' Group segment on its platform.
In the trade-for-trade segment no speculative trading is allowed and delivery of shares and payment of consideration amount are mandatory.
As per BSE and NSE, the move is part of the surveillance review "to ensure market safety and safeguard the interest of investors".
The exchanges have asked the trading members to take "adequate precaution" while trading in these scrips.
However, they added that "the transfer of security for trading and settlement on a trade-to-trade basis is purely on account of market surveillance and it should not be construed as an adverse action against the concerned company".
These securities would attract a price band of 5 per cent which would be the maximum permissible limit within which the share price can move.
