The Nifty’s gap between its 3.15 pm close and CAS settlement narrowed to 8 points on Thursday, from 55 points on Wednesday and 155 points on August 4, The Hindu BusinessLine reports. The index closed at 24,628 before the auction and settled at 24,636 after it. Rediff.com reports that the Sensex-Nifty closing divergence narrowed to 0.15 percentage points on Wednesday, with arbitrageurs and lower volatility helping. CAS, introduced on Monday, sets closing prices through a 3.15 pm to 3.35 pm auction for stocks with derivatives contracts, replacing the previous final-30-minute method. Analysts expect better price discovery and fewer end-of-day arbitrage opportunities, while Zerodha’s Nithin Kamath called for easier short selling, securities lending and genuine market-making.
