 Top Insider Purchases: Who Invested Millions in Their Business (May 11, 2026) I'm breaking down the latest insider trading data — when directors and CEOs buy millions worth of their own company's stock, it's a signal you can't ignore. **Largest Purchases of the Day:** * **Pulse Biosciences (PLSE)** — $13 million. Robert Duggan bought 660,000 shares at $19.69. This isn't just a purchase; it's a bid for control. The company is in the medical sector — the insider clearly sees an upside that the market hasn't priced in yet. * **Txo Partners (TXO)** — $9.5 million. Bob Simpson acquired 750,000 shares at $12.61. Energy sector. An +11% increase in stake — a serious position boost. * **Atara Biotherapeutics (ATRA)** — Ecor1 Capital bought an additional 507,000 shares (+49% to stake). Biotech with strong institutional support. * **Alphatec Holdings (ATEC)** — Keith Valentine increased his stake by 139%! Bought 135,000 shares at $7.38. Medical technology — the director is tripling down. * **SoFi Technologies (SOFI)** — CEO Anthony Noto bought 15,500 shares at $16. Fintech. When a CEO buys with their own money, it's the best signal. * **Starlink AI Acquisition Corp (OTAI)** — $2.2 million from Jkapital Ltd. at $10. AI company — intersects with our theme. * **Parsons Corp (PSN)** — CEO Carey Smith bought 12,500 shares at $49.97. Defense sector. * **Norwegian Cruise Line (NCLH)** — Director Zilla Bing-Thorn bought 29,500 shares at $17.69. Tourism is recovering. **My Strategy:** I track insider purchases in real-time through public sources. When a director or CEO invests their millions, it's more honest than any analyst report.
