CEO Klein buys 14,571 shares at $8.53 avg; holds 1.53M shares; 5 of 5 prior SSSS buys well-timed at 90d, avg 90d return +23.6%

Klein Mark D, Chairman, CEO and President, executed 2 separate open-market purchases totaling 14,571 shares for $124,221.99, raising his post-transaction holdings to 1,530,590 shares. His prior trading history at SSSS shows a consistent pattern: all 5 of his prior buys at this ticker were well-timed at the 90-day mark, with average 90-day returns of +23.6% (ranging from +6.7% to +59.9%). His cross-ticker track record reinforces this: 14 prior buys across all tickers with a 100.00% 90-day win rate and average 90-day return of +15.2%. The current price of $8.62 sits 4.3% below the 52-week high of $9.01, while the stock has advanced 46.8% over 90 days and 3.9% over 30 days. Notably, the company reported full-year net income of $62,328,070.00 with a P/E of 3.67, yet was unprofitable over its most recent full fiscal year—a divergence that warrants scrutiny of the earnings quality and timing of this buy activity.

Significance 8/10

CEO Klein buys 16,500 SSSS shares at $5.26; 5 of 5 prior SSSS buys showed +90d gains (18.4%, 26.2%, 6.7%, 11.7%, 29.7%)

Klein Mark D, the company's Chairman, CEO and President, purchased 16,500 shares at $5.26 on 2025-05-09, increasing his holdings from 1,199,519 to 1,216,019 shares. This buy is particularly noteworthy given his track record at SURO CAPITAL: his prior 5 trades at this ticker (all buys between August and December 2024) each generated positive 90-day returns, ranging from +6.7% to +29.7%, with a perfect 5-of-5 pattern of well-timed entries. The current stock price of $5.27 sits -20.9% from its 52-week high, though it has recovered +10.2% over the past 30 days. The company remains unprofitable with a net loss of $-806,715.00 over its most recent full fiscal year. The confluence of a seasoned insider's renewed accumulation, his demonstrated precision in timing at this specific ticker, and depressed valuation relative to annual highs creates a material signal worth close attention.

Significance 4/10

Klein Mark D (Chairman, CEO and President) executed his third open-market purchase at SSSS in as many trading days, acquiring 743 shares at $5.49 on 2024-12-02 and bringing his total holdings to 1,170,666 shares.

Significance 8/10

CEO Klein bought 81,257 shares ($417.6K) over 3 days at $5.03–$5.20; 90d win rate 100% on prior trades at SSSS.

Mark D Klein, Chairman, CEO and President, made 3 separate purchases totaling 81,257 shares for $417,610.70 between 2024-11-26 and 2024-11-29, raising his holdings to 1,169,923 shares. His blended average price of $5.14 represents a purchase well into the stock's 52-week range ($3.39–$5.40) and only 1.8% below the 52-week high. Notably, Klein has a perfect 90-day win rate (100.00%) across 5 prior buys at this same ticker, with each prior purchase followed by positive 90-day returns ranging from +5.1% to +29.7%. His cross-ticker track record also shows consistent results: 9 prior buys with an average 90-day return of +9.9% and a 100% win rate. The stock has appreciated +14.2% over the past 30 days and +34.2% over 90 days, suggesting the company may be in an improving phase. However, the company reported a net loss of $-5,452,245.00 and trades at a P/E of 27.89, raising questions about whether the higher valuation is justified by underlying fundamentals.

Significance 8/10

CEO Klein buys 12,000 shares ($46.1K) at $3.84; 1.09M post-transaction; strong same-ticker timing track record (5 of 5 prior buys well-timed at 90-day mark).

Klein Mark D, the Chairman, CEO and President, purchased 12,000 shares at $3.84, increasing his holdings to 1.09M shares. This follows a pattern: his prior 5 trades at SSSS were all buys, and all 5 were well-timed at the 90-day mark, suggesting consistent execution on conviction. His cross-ticker track record shows 8 prior buys with a 100.00% 90-day win rate and average 90d return of +7.4%, indicating disciplined open-market timing across multiple securities. The current stock price of $3.85 sits -18.4% from the 52-week high and -4.2% down over 30 days, positioning this purchase near depressed recent levels; his prior SSSS buys (Dec 2023, Nov 2023) also occurred after or during weakness and subsequently posted +5.1% to +8.3% 90-day returns. However, the company is currently unprofitable (net income of $-10,651,183.00) with a notably elevated P/E of 20.26 despite negative earnings, creating asymmetry between his demonstrated timing skill on this ticker and underlying fundamentals. For investors, the CEO's continued accumulation at historical discounts bears watching against earnings trajectory.
