SEBI has warned investors against fake WhatsApp stock tips and unauthorized trading calls circulated through private groups. Fraudsters allegedly use false profit claims, fake testimonials and misleading investment advice to lure unsuspecting investors. Business Today’s Nachiket Kelkar explains why the regulator has issued this advisory and how investors can protect themselves. SEBI has urged investors to avoid unknown WhatsApp groups, verify financial intermediaries through its official website and use authentic trading apps. The warning comes amid rising stock market participation and continued regulatory action against unregistered financial influencers and stock market manipulation.
