Insiders are net sellers (969,760 shares sold vs 796,974 bought) — management reducing exposure. Strong institutional ownership at 79.5% with 6 of 10 top holders actively accumulating this quarter.

- Wait for clearer whale activity before adding
- Monitor next earnings for institutional positioning changes
