CTO buys 10,000 shares at $1.89; stock down 39.3% in 30 days, but insider's cross-ticker track record shows 100% 90-day win rate.
Joseph M Wong, Chief Technology Officer of Arq, Inc., purchased 10,000 shares at $1.89 on 2026-03-17, increasing his holdings to 400,686 shares. This purchase occurs against a backdrop of severe near-term price deterioration—the stock has fallen 39.3% over the past 30 days and 35.3% over 90 days, trading 73.2% below its 52-week high of $7.73. However, Wong's own cross-ticker open-market history demonstrates a 100% win rate on buys at the 90-day mark with an average 90-day return of 40.1%; his single prior purchase at ARQ in May 2025 also posted a 59.6% 90-day gain. The buy aligns with a cluster pattern: 2 other insiders bought within the past 14 days, suggesting shared conviction at current levels. The company generated $35.1M in quarterly revenue with annual growth of 10.4% but remains unprofitable ($-653.0K quarterly net income), narrowing the basis for timing confidence to either operational recovery expectations or valuation mechanics rather than current profitability. The coincidence of Wong's disciplined historical timing, his same-ticker prior success, and concurrent insider accumulation warrants investor attention to whether this signals management's view of a floor in the decline.
