Sebi Chairman Tuhin Kanta Pandey said the market regulator is not looking at any changes to the Closing Auction Session, or CAS, even as the new closing-price mechanism came under fresh scrutiny after sharp expiry-day swings in the Sensex.
Pandey said Sebi expects market participants to understand the closing auction framework better over time and take part more actively. His comments came on a day when the Sensex saw a sharp move around the close during monthly derivatives expiry, renewing concerns among traders over how the auction-based system is affecting expiry-day settlement.
