The purchases occurred near the company's 52-week high of $5.76 (current price $4.99 is -13.4% below that peak). Notably, Campbell's prior trades at SELF have demonstrated a 4-of-5 pattern of well-timed buys, with 90-day returns averaging +4.3–+4.9% on three of his May 2024 purchases and 2025 activity tracking recent weakness.

WINMILL MARK CAMPBELL, President and CEO, purchased 10,000 shares at $5.67 on 2025-05-19, increasing his stake to 322.8K shares, a 3.2% increase to his existing position. The current price of $5.70 places this purchase within 0.0% of the 52-week high, with the stock advancing +10.0% over the prior 30 days and +9.8% over 90 days. SELF's fundamentals show quarterly revenue of $3.1M, net income of $555.2K, and a P/E of 27.14, reflecting moderate profitability at a price that values the company at $64.6M. His 5 prior purchases at SELF have all yielded positive 90-day returns (ranging +4.3% to +4.9%), consistent with his cross-ticker track record of a 100% 90-day win rate across 12 prior buys, though his 30-day average return of -2.8% cross-ticker suggests near-term pullback risk following acquisition. This purchase occurs near the stock's 52-week peak after a meaningful recent rally, which diverges from the typical entry points of his prior SELF purchases in May 2024.
