Why it matters

This adds a fresh, timestamped datapoint on director selling activity, but the 10b5-1 pre-arranged nature typically limits immediate fundamental interpretation.

02

Market read

MGNI receives a new insider-sale datapoint (~$168.5K) dated 2026-06-10; likely low incremental trading signal.

03

What to watch
