NEUTRAL — WATCH
No clear whale direction for NBIS. Bullish and bearish signals roughly cancel out. Short interest at 19.8% of float — moderate bearish positioning. Insiders are net sellers (660,371 shares sold vs 500,000 bought) — management reducing exposure.
Action Plan
- Hold existing positions — no strong directional signal
- Wait for clearer whale activity before adding
- Watch short interest trend (currently 20%) — covering = bullish catalyst
- Monitor next earnings for institutional positioning changes
