Insider Trading on May 19: Who's Buying, Who's Selling

![Иллюстрация к посту](/blog/image/5026) Insider Trading on May 19: Who's Buying, Who's Selling I've analyzed the latest insider trading data for today. The picture is mixed — there are significant purchases, but also serious sales. Top Purchases (Insiders Accumulating): • 51Talk Online Education Group — CEO Huang Jack Jiajia bought $2.14 million at $25.42. Confidence in Chinese edtech. • Vivani Medical — Director Williams Gregg acquired $2 million at $1.26. Medical startup — a bet on a breakthrough. • Stoneco Ltd (STNE) — CFO Ventura Salgado Diego bought $217,000 at $9.66. +8% to his stake — the CFO knows what he's doing. • Genesis Energy (GEL) — VP Gaspard Garland bought $201,000, increasing his stake by 50%. Pipeline operator. • Taiwan Semiconductor (TSM) — VP Tien Bor-Zen bought $139,000. Modest but symbolic. Top Sales (Caution): • TSMC — VP Chuang Tzu-Sou sold $14 million at $69.83. One VP buys, another sells — disagreements? • Sony Group — Director Yoshida Kenichiro sold $9 million. Another Sony top manager cashed out $400,000. • Aflac — Japan Post Holdings sold $2.75 million. Strategic exit. • Nebius Group (NBIS) — CRO Boroditsky Marc sold $979,000 at $217.55. Key takeaway: Purchases are in niche companies (edtech, medtech, energy), while sales are in mainstream giants (TSMC, Sony, Aflac). Insiders are shifting from blue chips to riskier stories. What does this mean for the market? Classic pattern: when TSMC top managers sell $14 million and Stoneco's CFO buys — it's worth looking at undervalued sectors.
