CEO Chih-Hsiang Lin sells 59,000 AAOI shares at $166.53; stock now $170.81 despite 90d rally +84.4%

Chih-Hsiang (Thompson) Lin, President and CEO, sold 59,000 shares on 2026-06-12 at $166.53, reducing his holdings from 1.36M to 1.30M shares (-4.3%). The timing is noteworthy: the stock has rallied 84.4% over the past 90 days and currently trades at $170.81, yet the CEO executed this sale below current prices. His prior AAOI trades (4 of 4 measurable) achieved well-timed outcomes, though his cross-ticker track record shows 1 prior sell with limited outcome data. The company is unprofitable (net income $-14.3M) despite strong revenue growth of 82.8% year-over-year, operating at a $13.7B market cap. The sale occurs within a broader pattern of recent selling activity (a prior sale on 2026-05-19 outcome not yet measurable), warranting examination of whether this reflects changed conviction regarding valuation or near-term prospects.
