India Implements Closing Auction Session, Causing Nifty Surge and Market Adjustment
India's stock markets introduced the Closing Auction Session (CAS) on August 3 for futures and options (F O) eligible stocks, replacing the previous volume-weighted average price (VWAP) method for determining closing prices. CAS runs from 3:15 pm to 3:35 pm, matching buy and sell orders to establish a single closing price. This change caused a notable 200-point surge in the Nifty index after continuous trading ended, leading to temporary divergences between indices and futures. Exchanges and experts attribute this to low initial participation and expect adjustments as traders adapt to the new system.
