BSE would shift 26 stocks to the trade-to-trade or 'T' group, while NSE would transfer 11 scrips to this category, the exchanges said in separate notifications.
Some of the stocks which would be moved to the 'T' group on both the exchanges are -- Gemini Communication, Indiabulls Wholesale Services, Ind-Swift and Kesoram Industries.
Under the trade-to-trade segment, no speculative trading is allowed and delivery of shares and payment of consideration amount are mandatory.
As per the bourses, the move is part of preventive surveillance measures to ensure safety of the market and safeguarding the interest of investors.
The exchanges have advised the trading members to take "adequate precaution" while trading in these scrips as the "settlement will be done on trade-to-trade basis and no netting off positions will be allowed".
However, they said "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".
Besides, these stocks would attract a circuit filter of up to 5 per cent which would be the maximum permissible limit within which the share price can move.
