 ️ Who buys stocks when the market panics? Insiders. May 15, 2026 — another correction day, but insiders of the largest companies are buying stocks in record volumes. Here's who loaded up big: Biotech — the main magnet for money The fattest purchase of the day — Genedx Holdings (WGS). Keith Meister, director and 10% shareholder, entered with $13.7 million at $39.19, increasing his stake by 7%. The company specializes in genetic testing. Pulse Biosciences (PLSE) — legendary investor Robert Duggan (the same one who made Pharmacyclics) bought another $13 million at $19.69. His stake is 49 million shares. Rallybio Corp (RLYB) — fund Adar1 Capital loaded up with $1.1 million, increasing its stake by 10%. Sensei Biotherapeutics (SNSE) — Millennium Management bought on the dip, +$818K. On Holding (ONON) — triple signal All three founders and CEOs of the company (Caspar Coppetti, David Allemann, Olivier Bernhard) synchronously bought 60,000 shares each — totaling $6.6 million at $36.64. When the entire C-level team loads up simultaneously, it's not a coincidence. ️ Raw materials and energy — Alpha Metallurgical Resources (AMR) — $2.8 million at $189.22 — TXO Partners — $3.9 million at $12.97 — Global Partners LP — $736K — Cresud Inc — $713K Other notable purchases — Nomad Foods (NOMD) — $912K, +20% to stake — Valvoline (VVV) — CFO bought $318K, +42% to stake — Harrow (HROW) — CEO bought $302K — E.W. Scripps (SSP) — $257K, +101% to stake — CVB Financial — $500K What does this mean? Insiders buy on dips — especially in biotech and consumer sectors (ONON). When top managers invest their own money, rather than just giving optimistic forecasts, it's the most honest signal in the market. Source: OpenInsider data for 05/15/2026.
