NEUTRAL — WATCH
No clear whale direction for COHR. Bullish and bearish signals roughly cancel out. Insiders are net buyers (7,777,412 shares bought vs 7,630,124 sold) — bullish conviction from management. Strong institutional ownership at 91.6%, but 3 of 10 top holders are distributing.
Action Plan
- Hold existing positions — no strong directional signal
- Wait for clearer whale activity before adding
- Monitor next earnings for institutional positioning changes
