NEUTRAL — WATCH
No clear whale direction for ALAB. Bullish and bearish signals roughly cancel out. Short interest at 10.7% of float — moderate bearish positioning. Insiders are net buyers (796,974 shares bought vs 786,760 sold) — bullish conviction from management. Strong institutional ownership at 79.5% with 6 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
