The Securities and Exchange Board of India has again cautioned investors against transacting in unlisted securities of public limited companies through electronic platforms and websites that are not authorized or recognized by the regulator. It reiterated that only recognized stock exchanges are authorized to provide platforms for fundraising and trading in securities, and warned investors not to share sensitive personal information on such sites. The warning follows SEBI's earlier advisories on similar activity, including unauthorized virtual trading platforms and unregistered online platforms offering unlisted debt securities. Investors using these unauthorized platforms would not have access to SEBI or exchange investor protection measures, exchange-administered grievance redress mechanisms, or the online dispute resolution framework run by exchanges and depositories.
