In this episode of Trading Takes, Sam sits down with Edwin Dorsey (@StockJabber), founder of The Bear Cave newsletter. Edwin has become one of the most respected watchdogs in the trading world, uncovering pump-and-dump scams, exposing fraudulent companies, and helping traders understand the hidden mechanics of modern market manipulation. In this episode, Edwin shares how scams run through WhatsApp groups, social media ads, and fake asset managers have siphoned billions of dollars from unsuspecting investors. He explains how he infiltrates these groups, what signs to look for before a stock collapses 90%, and why regulators have been slow to act. Edwin also discusses his new website — StopNasdaqChinaFraud.com, a crowdsourced tool for tracking scam promotions, and explains how his newsletter gives readers an edge in spotting fraud before it hits the headlines.
