    HALTED AT $71.60 · ▲ 26.0% ON THE DAY · 36.5× 5M RVOL · RANK #17

    JUSTIFIEDCONFIDENCE4/5

    IRON is up 26.0% pre-market ahead of topline Phase 3 APOLLO trial results for bitopertin in erythropoietic protoporphyria. The pending-news trading halt indicates the move is event-driven, and a major Phase 3 readout plausibly supports a move of this size.

    WHYA 26% pre-market move is large, but proportionate to an imminent Phase 3 topline-results announcement with trading halted for news pending.
