NEUTRAL — WATCH
No clear whale direction for ALAB. Bullish and bearish signals roughly cancel out. Short interest at 10.1% of float — moderate bearish positioning. Insiders are net sellers (1,457,356 shares sold vs 846,558 bought) — management reducing exposure. Strong institutional ownership at 79.7% with 7 of 10 top holders actively accumulating this quarter.
Action Plan
- Hold existing positions — no strong directional signal
- Wait for clearer whale activity before adding
- Monitor next earnings for institutional positioning changes
