Moderna is trading at $144.62, up +8.47%, rebounding after falling 23.55% to $133.32 on August 20.
- No clear new company-specific catalyst was identified for the August 21 rebound.
- Investor interest remains elevated after Moderna and Merck reported positive Phase 3 melanoma-vaccine results on August 19.
- The broader biotech sector is weaker, suggesting todayβs move is primarily a volatile, company-specific rebound rather than sector momentum.
