Jaguar Health Soars 32% as Rare-Disease Pipeline News Meets Thin Post-Split Float
Jaguar Health (JAGX) rose 32% to $9.32 after reporting progress in its crofelemer pipeline for rare pediatric diseases. The surge is attributed to a thin float post-reverse split and company-specific news, with the biotech sector and broader market showing little correlation. The company aims to submit a new drug application for crofelemer in Q2 2027, but faces risks of dilution and regulatory setbacks.
