The SGF block sale alone is 18% of ADV coverage — watch for secondary offering announcements or further distribution by the 10% owner. CEO and CAO selling concurrently at $205 adds to the overhang narrative. Short-term price direction likely negative as market absorbs distribution.

Executive Summary
