The Securities and Exchange Board of India (SEBI) has proposed reviewing certain aspects of the Closing Auction Session (CAS), market timings and the settlement methodology for derivatives contracts, including two options for determining expiry-day settlement prices for index and single-stock derivatives.
The CAS framework was introduced in the equity cash segment of stock exchanges for stocks on which derivatives contracts are available, with effect from August 3, 2026, with the objective of facilitating efficient and transparent price discovery of the closing price of securities.
