 Which insiders loaded up last week? Analysis of top trades on May 11 While the market fluctuates on news of ceasefires and tariffs, insiders are voting with their money. I've compiled the largest purchases from yesterday — there are interesting signals there. Genedx Holdings (WGS) — $46.8 million Director Keith Meister bought an additional $46.8 million at $38.84, increasing his stake by 34%. The biggest check of the day. Genetic testing — a sector insiders clearly consider undervalued. Odyssey Therapeutics (ODTX) — $30 million total Director Nan Li invested $20 million at $18 (+50% to stake). Sr One Capital added another $10 million. Biotech with three consecutive insider purchases — confidence from insiders. Pulse Biosciences (PLSE) — $13 million Robert Duggan (legendary investor who earned $1.9 billion on Pharmacyclics) bought $13 million at $19.69. His entry is a signal in itself. Other notable: • Mobia Medical (MOBI) — two insiders for $9.87 million at $15 (one of them increased stake by 61%) • Atara Biotherapeutics (ATRA) — Ecor1 Capital bought $4.74 million at $9.35 • Starlink AI Acquisition (OTAI) — Jkapital for $2.2 million at $10 (AI SPAC) • Universal Display (OLED) — CEO for $1.03 million at $93.43 • Alphatec (ATEC) — director for $996K, increased stake by 139% • Legalzoom (LZ) — CEO Jeffrey Stibel for $769K at $6.15 • Lamb Weston (LW) — CFO for $409K at $40.92 Overall trend: biotech and AI — two sectors where insiders are pouring money. Out of the 15 largest deals — 5 in biotech and 1 AI-SPAC. The rest are scattered purchases in oil (TXO), cruises (NCLH), and payment services (ADP). Data: OpenInsider, 11.05.2026
