LEAN BEARISH
Whales showing caution on WDC. Distribution signals outweigh accumulation. Insiders are net sellers (176,347 shares sold vs 23,145 bought) — management reducing exposure. Strong institutional ownership at 103.4%, but 2 of 10 top holders are distributing.
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
