Why is REGN moving today?

-0.7%

REGN is -0.7% today, inside the ordinary range for a session (under 3%). No stories about it reached the feed in the last 24 hours.

What this does not prove. A story on the same day is evidence of timing, not of cause: it explains a move only if it accounts for the size and the direction, and most single-stock moves carry a sector or index component too. Nothing here is a forecast.
