AI Summary

7.0
Positive

ARGX is a high-quality but fully valued immunology growth story: sustained VYVGART expansion and myositis approval potential support upside, but investors should demand proof that the $2.2B Forte deal can create a second franchise, as any VYVGART slowdown or pipeline disappointment could pressure the premium valuation.
