LEAN BULLISH
Net positive whale activity for ALAB. Smart money shows interest, but signals are mixed. Short interest at 10.1% of float — moderate bearish positioning. Insiders are net sellers (1,880,698 shares sold vs 846,558 bought) — management reducing exposure. Strong institutional ownership at 80.6% with 6 of 10 top holders actively accumulating this quarter.
Action Plan
- Consider building a position on pullbacks
- Set stop-loss below key support level
- Re-evaluate if insider selling accelerates
