India's Closing Auction Session Causes Volatility and Price Discrepancies Amid Derivatives Expiry
India's new Closing Auction Session (CAS), introduced on August 3 to improve end-of-day price discovery and reduce manipulation, has led to significant market volatility. During the first monthly derivatives expiry, the Sensex plunged over 2,200 points before recovering nearly 2,000 points, while options prices swung dramatically. Sharp price gaps between NSE and BSE for some bank stocks also emerged. Regulators, including SEBI Chairman Tuhin Kanta Pandey, have ruled out immediate changes, emphasizing the need for greater market participation and liquidity to stabilize CAS.
