Why is Moderna stock sliding today?

Moderna's stock is down 5.9% in pre-market trading after Citi downgraded it to Sell with a $80 price target, implying 60% downside. The downgrade cites valuation concerns and a lack of justification through comparisons. Additionally, a court denied Moderna's motion to dismiss a patent lawsuit, adding legal risk. The stock has surged 223% since August due to positive trial results, but broader market conditions and mixed peer sentiment offer little support.
