Moderna shares have plummeted approximately 20% following the leak of partial Phase 3 data for its melanoma vaccine, which showed a 42% risk reduction but failed to meet market expectations or triggered a sell-the-news reaction. This event underscores the extreme volatility inherent in biotech equities, where even positive clinical data can trigger sharp sell-offs if it does not align with inflated investor expectations. The move is isolated to the sector but highlights the fragility of growth-oriented healthcare valuations.
