Why are they buying?
AI · discretionary · catalyst credible · documentedInsiders likely purchased shares to signal strong conviction after the stock plunged following mixed Phase 3 LEVEL trial results for TNX-103 in August 2026, where management highlighted robust subgroup data and biomarker improvements.
Tenax shares plummeted nearly 90% after its phase 3 trial missed its primary endpoint, but management and major stakeholders like ADAR1 Capital/Daniel Schneeberger aggressively bought millions of dollars in open-market shares while pointing to significant reductions in NT-proBNP and positive effects in sicker patient subsets.
