No clear whale direction for WDC. Bullish and bearish signals roughly cancel out. Insiders are net sellers (171,021 shares sold vs 23,145 bought) — management reducing exposure. Strong institutional ownership at 100.6% 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
