The Securities and Exchange Board of India (SEBI) has announced a revision of the eligibility criteria for the entry and exit of stocks in the derivatives segment. This move aims to ensure that only high-quality stocks with sufficient market presence are allowed to trade in this segment. The updated norms are part of SEBI's ongoing efforts to enhance the integrity and efficiency of the financial markets. Additionally, SEBI has amended regulations to restrict the association of registered entities with unregistered advisors, further tightening the regulatory framework governing market participants.
