No clear whale direction for STX. Bullish and bearish signals roughly cancel out. Insiders are net sellers (264,526 shares sold vs 187,227 bought) — management reducing exposure. Strong institutional ownership at 89.6% with 4 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
