Moderna and Merck's personalised mRNA cancer vaccine just hit its Phase 3 targets in melanoma.. recurrence risk cut by roughly half.. the first late-stage win for individualised mRNA cancer therapy. And here's the part most people miss: MRNA is the most shorted stock in the S&P 500.. roughly 33% of its float sold short. A catalyst this big hitting the most crowded short in the index is a textbook squeeze setup. Understanding why that amplifies a move is the whole game. #moderna #mrna #daytrading #stocks #investing
