LEAN BEARISH
Whales showing caution on NBIS. Distribution signals outweigh accumulation. Short interest is elevated at 20.3% of float — significant bearish pressure but squeeze potential exists. Insiders are net sellers (697,934 shares sold vs 500,000 bought) — management reducing exposure. Strong institutional ownership at 63.2% with 8 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
