The Canadian Securities Administrators (CSA) issued an investor warning about fraudulent investment groups promoted on social media that may be running “ramp and dump” schemes, in which fraudsters push up the price of low-priced or thinly traded stocks and then sell their holdings, leaving other investors with losses when the price falls. These schemes are increasingly organized through social media and closed messaging platforms such as WhatsApp, Discord and Telegram, where scammers pose as knowledgeable investors, promote specific stocks and pressure individuals to buy. The CSA described tactics including contacting potential victims on platforms such as Facebook and Instagram to build trust, moving them into encrypted group chats, claiming access to non-public “inside” information, using fake credentials or impersonating well-known individuals or firms, and targeting small, unfamiliar stocks with limited public float, sometimes headquartered abroad. The CSA urged investors to be wary of unsolicited investment advice and “investment group” chats, to verify adviser registration and disciplinary history using the CSA’s National Registration Search, and to consult the CSA’s Investor Alerts list of firms to avoid. Suspected victims are advised to contact their local provincial securities regulator, the Canadian Anti-Fraud Centre, their bank and local police.
