This Fin Shorts piece from Lumic delves into the recent changes announced by SEBI concerning the stock market's Closing Auction Session (CAS) and derivatives settlement. Effective December 7, 2026, the CAS timings are shifting, now scheduled to run from 3:30 pm to 3:40 pm. A key point to note is that only market and limit orders will be permissible during this period, with stop-loss orders being disallowed. Furthermore, SEBI has updated F&O expiry rules for derivatives settlement. Trading in expiring index derivatives will cease at 3:30 pm, while stock derivatives will continue until 3:45 pm. These adjustments by the market regulator, SEBI, are aimed at enhancing market efficiency and transparency for Indian bourses like NSE and BSE. Understanding these new stock market trading rules is crucial for traders and investors navigating the Indian financial markets.
