Why Moderna (MRNA) Stock Is Down Today
Moderna (MRNA) shares fell 2.9% after a Rothschild & Co analyst downgraded the stock to Sell, citing valuation concerns. The analyst raised the price target to $81, implying a 46% downside from the previous close of $150.81. This follows positive Phase 3 trial results for Moderna's cancer vaccine candidate, though the analyst deemed the market's reaction overexuberant. The stock later recovered slightly to $146.24.
