CIRCULAR
SEBI/HO/MRD/MRD-PoD-3/P/CIR/2024/85 June 20, 2024
To
All Recognized Stock Exchanges
Dear Sir/Madam,
Subject: Modification in duration for Call Auction in pre-open session for Initial
Public Offer (IPO) and Relisted scrips
1. Paragraph 17.2 of Chapter 1 of SEBI Master Circular No. SEBI/HO/MRD2/POD-
2/CIR/P/2023/171 dated October 16, 2023 for ‘Stock Exchanges and Clearing
Corporations’ prescribed framework for call auction in pre-open session for Initial
Public Offer (IPO) and relisted scrips.
2. It was observed that during the call auction in pre-open session for certain IPO
and relisted scrips, orders were placed at higher price in large volumes and
significant portion of such orders were cancelled just before the closure of call
auction session. This may have created false demand and supply and possibly
manipulating the price of the scrips to the detriment of common investors.
3. In order to curb the misuse of the call auction session, based on the report of
Working Group of Stock Exchanges and recommendations of Secondary Market
Advisory Committee of SEBI, it has been decided to modify the current provisions
related to call auction session for IPO & relisted scrips and introduce additional
surveillance measures at stock exchanges.
4. Accordingly, paragraph 17.2.1 of the aforesaid Master Circular has been modified
as under:

17.2.1.2.The session shall close randomly during last ten minutes of order

window. Such random closure shall be system driven.”
5. In order to enhance the surveillance mechanism at stock exchanges for pre-open
call auction session for IPO and relisted scrips, it has been decided that stock
exchanges shall have the following additional surveillance mechanisms:
5.1. Stock exchanges shall have adequate surveillance mechanisms for pre-open
call auction session for IPO or relisted scrips to avoid any kind of manipulation.
