With argenx trading just below the consensus fair value of €724.38 and a last close of €711.80, market sentiment appears nearly aligned with the most widely followed growth narrative. The close proximity between price and valuation highlights heightened analyst confidence, yet leaves little room for error or surprise.

“Increasing peak sales estimates for Vyvgart in myasthenia gravis, with models projecting up to $6.4B in gMG by 2034 and an expanded role for new indications, are materially raising valuations.

Analysts cite accelerating Vyvgart uptake, global expansion, and additional pipeline opportunities as drivers of potential quadrupling of sales and strong operating cash flow by decade's end.”
