Why it moved

No clear catalyst identified

No reliable news, earnings or analyst driver was found for this move. A move this size without an obvious driver is most likely flow/positioning-driven rather than a fundamentals story.

Additional context: AXSM dropped 5.73% amid long-term speculation on Auvelity's Alzheimer's expansion.

Verdict — was the move justified?

⚪ No clear catalyst

An unusually large move with no reliable catalyst identified — most likely flow/positioning-driven rather than news-driven.
