Event Summary

SEBI Chairman Tuhin Kanta Pandey confirmed that the Closing Auction Session (CAS) for futures and options-eligible stocks is here to stay, while the regulator analyzes feedback and data for potential improvements. CAS, effective August 3, changes closing price determination by ending continuous trading at 3:15 p.m. and using an auction to set the official closing price. Pandey stated that SEBI is reviewing concerns from market participants, social media discussions, and expiry-date data, but sees no tracking error issues. He emphasized that any tweaks will be data-based and that the regulator will not revert to the previous VWAP system. Some concerns may stem from outdated systems, and participation is expected to improve the mechanism.
