SEBI vide its Circular dated 11th April, 2023 issued a Circular for All Stock Exchanges.
The Circular states:
SEBI announced the new framework for fixing the price band for trading in share market on the first day of listing after an IPO. The framework aims to streamline price band discovery on the secondary market. The decision has been taken after discussions with stock exchanges and the Secondary Market Advisory Committee (SMAC).
Several stock exchanges hold call auction sessions when a stock is about to trade for the first time following its IPO. It’s possible that the equilibrium price or found price following such call auction sessions will vary depending on the exchange. If the gap between these discovered prices is wide, price bands on different exchanges could be widely off from one another, giving investors a false impression of the price band.
The following has been decided for trading on the first day pursuant to IPO or re-listing (including re-listing on account of the scheme of the arrangement but excluding scrips for which derivative contracts are available):
This circular shall come into force with effect after 60 days on 10th June, 2023.
