The Securities and Exchange Board of India (SEBI) has implemented significant changes to the equity futures and options (F&O) segment, effective November 21, 2024. These changes include modifications to lot sizes, aimed at enhancing market efficiency. Additionally, SEBI is set to launch F&O contracts for 43 securities, including notable companies such as Adani, Paytm, Zomato, and LIC, starting December 13, 2024. This initiative is part of SEBI's broader efforts to improve market integrity and protect retail investors, particularly in the context of recent concerns regarding SME IPOs. SEBI's proposals also encompass increased scrutiny of related-party transactions and the abolition of mandatory security deposits for public issues, aimed at facilitating business operations for issuers.
