AI Summary

5.0
Neutral

BIIB is now a credible but unproven transition story—real Alzheimer's upside from Leqembi/diranersen and diversification via Apellis is being offset by a recent clinical miss, litigation, and softer MS earnings, so the stock looks fairly valued but likely won't re-rate unless near-term pipeline wins restore confidence.
