LEAN BEARISH
Whales showing caution on WDC. Distribution signals outweigh accumulation. Insiders are net sellers (170,030 shares sold vs 2,690 bought) — management reducing exposure. Strong institutional ownership at 101.2% with 4 of 10 top holders actively accumulating this quarter.
Action Plan
- Avoid new long positions until whale activity shifts
- Insider selling suggests management has near-term concerns
- Consider trimming if position size is large
- Set alerts for insider buying or SI decrease as reversal signals
📈 Options Flow 期权异动
