Sebi has proposed a regulatory framework to deal with suspicious trading around the presence of material non-public information. The framework would deal with malpractices by market participants, who use new-age technologies by way of encrypted or vanishing messages, and modus operandi to evade the law. The proposed rules would prohibit individuals from engaging in suspicious trading around the presence of material non-public information unless they can effectively rebut the presumption that they are violating the securities laws.
