Moderna Shares Tumble After Citi Delivers Stark Sell Rating

Moderna (MRNA) shares dropped 5% after Citi downgraded the stock to Sell, citing valuation concerns despite a price target increase to $80. Citi analyst Geoff Meacham noted current share price may overestimate cancer-drug pipeline success, with melanoma trial results not necessarily applying to other cancers. Citi's valuation analysis suggests even optimistic oncology sales forecasts fall short of recent trading levels.
