Why Greenwich LifeSciences Stock Tanked Today

Shares of Greenwich LifeSciences (NASDAQ: GLSI) were tanking 27.8% as of 3:34 p.m. EDT on Monday. The huge drop came after the company published a poster over the weekend at the American Association for Cancer Research (AACR) Annual Meeting showing five-year immune response data from a phase 2b study of immunotherapy GP2. You might think that Greenwich's phase 2 results were horrible after seeing the biotech stock plummet today.
