CFO Mark Herndon buys 80 HKHC shares at $33.03; holdings rise 66.7% to 200 shares amid cluster activity
Mark Herndon, CFO of Horizon Kinetics Holding Corp, purchased 80 shares at $33.03 on 2026-03-18, increasing his total holdings from 120 to 200 shares (+66.7%). The purchase occurred within a 14-day window in which 2 other insiders also bought, forming a cluster pattern. However, Herndon's cross-ticker track record shows limited predictive value: 2 prior buys averaged -7.9% 30-day return and -4.4% 90-day return with a 0.00% win rate. At HKHC specifically, his two prior purchases (on 2025-11-20 and 2025-06-04) neither generated positive 90-day returns, indicating a timing pattern of 0 of 2 well-timed buys at this ticker. The company shows solid fundamentals—revenue growth of +27.4% year-over-year and net income of $7,235,000.00 in the latest quarter—but trades at a P/E of 79.07, and the stock is down 27.7% from its 52-week high of $47.00 despite recent momentum (+19.3% in 30 days, +42.6% in 90 days). The cluster buy pattern warrants tracking to determine whether multiple insiders see genuine value or whether their prior execution has simply been ineffective.
CFO Mark Herndon buys 100 HKHC shares at $29.00, raising stake 500% to 120 shares; stock at $27.60, down 27.4% in 90 days.
Herndon's 100-share purchase at $29.00 on 2025-11-20 represents a substantial increase in his HKHC position (+500.0% vs pre-transaction holdings of 20 shares), yet occurs while the stock trades 41.3% below its 52-week high and has declined 27.4% over 90 days. His prior trade at this same ticker (2025-06-04) generated a -5.4% 90-day return, establishing a pattern of unfortunate timing at HKHC. The company shows compelling fundamentals—revenue of $17,893,000.00, net income of $7,235,000.00, and explosive annual revenue growth of +1580.3%—and trades at a P/E of 5.39, yet the recent price deterioration and the insider's unfavorable historical timing at this ticker suggest investors should examine the gap between reported earnings strength and current market sentiment.
CFO Herndon Mark purchases 20 shares of HKHC at $40.18; company shows exceptional revenue growth of +1580.3% YoY with profitable operations.
Herndon Mark, the Chief Financial Officer of Horizon Kinetics Holding Corp, executed a purchase of 20 shares at $40.18 on 2025-06-04, establishing an initial position in the stock. The transaction occurs within context of dramatic fundamentals: the company reported annual revenue growth of +1580.3%, net income of $22.8M against quarterly revenue of $19.8M, and a valuation multiple (P/E: 6.60) at the lower end of typical equity ranges. The current stock price of $41.00 represents -22.6% from its 52-week high of $53.00, suggesting the purchase was made during a pullback from recent peaks, though the stock has advanced +17.1% and +20.6% over the preceding 30 and 90 days respectively. The modest share count and small dollar transaction value limit material insight into executive conviction, but the buy does occur in a period of demonstrated stock strength and against a backdrop of explosive revenue acceleration.
