Sebi's Closing Auction Mechanism Causes Nifty Drop and ETF Valuation Challenges
India's Securities and Exchange Board (Sebi) introduced a new closing auction session (CAS) mechanism on August 3 to determine stock closing prices via a single equilibrium-price auction within a 3% range of a reference price. This led to a sharp 271-point Nifty drop triggered by a bid on Bharti Airtel below its reference price, possibly due to a seller error. The CAS also poses valuation challenges for exchange-traded funds (ETFs) holding stocks with mixed CAS eligibility, affecting real-time net asset value calculations until all stocks join CAS.
