Moderna Drops After Analyst Downgrade, Trial Letdown
Moderna (MRNA) shares fell 3% in pre-market trading after William Blair downgraded the stock to Market Perform, citing valuation concerns and Phase 3 trial results. The analyst sees a narrow cushion for investors due to high success probability assumptions. Citi maintains a Sell rating with an $80 price target. The decline is driven by company-specific factors, not broader market trends. Recent Phase 3 data showed a 42% reduction in melanoma recurrence, below prior Phase 2b results.
