LEAN BEARISH
Whales showing caution on MU. Distribution signals outweigh accumulation. Insiders are net sellers (422,205 shares sold vs 43,176 bought) — management reducing exposure. Strong institutional ownership at 82.2%, but 3 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
