NEUTRAL — WATCH
No clear whale direction for MU. Bullish and bearish signals roughly cancel out. Insiders are net sellers (399,705 shares sold vs 43,176 bought) — management reducing exposure. Strong institutional ownership at 83.2%, 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
