NEUTRAL — WATCH
No clear whale direction for STX. Bullish and bearish signals roughly cancel out. Insiders are net sellers (189,903 shares sold vs 104,212 bought) — management reducing exposure. Strong institutional ownership at 85.4% with 6 of 10 top holders actively accumulating this quarter.
Action Plan
- Hold existing positions — no strong directional signal
- Wait for clearer whale activity before adding
- Monitor next earnings for institutional positioning changes
