SEBI has made major changes to trading for stocks on the debut day following the completion of the initial public offerings (IPO). The new rules will take effect once stock exchanges adjust their trading systems to match them. Stocks will trade in the regular session for 45 minutes after being listed.
The stock's closing price at this special session will serve as the reference point when it enters regular session. Stocks with IPO sizes less than Rs 250 crore would face a circuit filter of 5%. A SEBI circular stated that the circuit filter limit will rise to 20% if an IPO is larger than Rs 250 crore.
For issues less than Rs 250 crore, trades will only be made on a trade for trade basis during the first 10 days after listing. This would mean that there is no opportunity to day trade stocks of smaller companies in this time period. This rule does not apply to securities worth more than Rs 250 crore.
