AI Summary

7.0
Positive

ARGX has evolved into a cash-generative immunology platform, with ALKIVIA potentially extending VYVGART into high-unmet-need myositis, but its premium valuation already assumes successful indication expansion and pipeline execution—favor holding/adding only if detailed data, regulatory progress, and VYVGART growth continue to exceed expectations.
