Sean Michael Oconnor, who was Executive Vice-Chairman of the Board, executed two separate sales totaling 150,000 shares for $19,993,050.00 on June 12 and June 15, 2026, at blended average price $133.29. The transactions reduced his holdings by 12.1% to 1,086,921 shares. This activity occurs as SNEX trades at $135.73, near the 52-week high of $138.47 and up 87.5% over 90 days and +23.2% over 30 days. Across his cross-ticker open-market history, Oconnor's 10 prior sells averaged a 90-day well-timed rate of 100.00%, indicating his prior sales were consistently made before subsequent stock declines. At SNEX specifically, his 2 measurable prior sales (on 2026-02-09 and 2026-02-10) each posted negative 90-day returns of -2.4% and -2.2%, establishing a pattern of well-timed exits at this ticker. The current sale comes after substantial recent appreciation and near historical highs, consistent with his demonstrated execution pattern.

Executive Vice-Chairman Sean Michael Oconnor sells 300,000 SNEX shares for $33.2M via 10b5-1 plan

Sean Michael Oconnor, who was Executive Vice-Chairman, executed 3 separate sales totaling 300,000 shares for $33,166,803.15 at an average price of $110.56 on May 15, 18, and 19, 2026. This represents a -19.5% reduction in his holdings from 1,536,921 to 1,236,921 shares. The sales occurred under a pre-arranged 10b5-1 trading plan, meaning execution was scheduled rather than discretionary. His prior 5 sales at SNEX showed average 30-day returns of -43.7% to -57.8%, with 90-day returns ranging from -47.0% to -2.2%, establishing a pattern of stock weakness following his sales at this specific ticker. The current price of $109.37 sits -12.8% from the 52-week high of $125.42, suggesting the stock remains near elevated levels relative to recent history.

Executive VP-Chairman O'Connor sells 80,000 SNEX shares for $9,980,360.00; 5 of 5 prior same-ticker sells preceded declines at 90-day mark

Sean Michael O'Connor, Executive Vice-Chairman, executed two separate sales totaling 80,000 shares for $9,980,360.00 (blended average $124.75) on 2026-02-09 and 2026-02-10, reducing his holdings to 854,127 shares. His prior trading history at StoneX shows a consistent pattern: all 5 previous sales at this ticker were well-timed at the 90-day mark, with declines ranging from -28.0% to -57.8%. The current price of $85.00 sits at the 52-week high, yet O'Connor has executed this sale amid a recent 30-day surge of +22.4% and 90-day gain of +43.4%—the inverse of his historical post-sale performance at this ticker. This divergence between current price strength and O'Connor's historical behavior pattern merits examination, particularly given his 100% success rate in prior sales at SNEX preceding negative 90-day returns.

StoneX EVP O'Connor sells 37,500 shares for $3.4M; stock up 23.2% in 90 days post-transaction despite track record of well-timed sells

Sean Michael O'Connor, Executive Vice-Chairman, sold 37,500 shares across 2 separate transactions—34,083 shares at $89.63 on 2025-04-29 and 3,417 shares at $90.57 on 2025-05-01—for a combined $3,364,324.03 at a blended average of $89.72. His holding in SNEX has declined 3.5% from 1,057,167 to 1,019,667 shares, yet the stock has rallied +23.2% in the 90 days following these sales, marking a departure from his prior pattern at this ticker: his 3 previous sales at SNEX were each well-timed (negative 90-day returns of -57.8%, -57.8%, and -53.4%), and his cross-ticker track record shows a 100% well-timed sell rate over 3 prior open-market transactions. This sale occurs with SNEX near its 52-week high of $59.96, fundamentals remain solid with 9.0% annual revenue growth and a P/E of 6.95, and the timing represents a notable inflection point relative to the insider's demonstrated historical precision in avoiding post-sale appreciation.

SNEX CEO O'Connor sells 40,000 shares for $4,077,800 over 3 days; holds 1,130,651 post-sale in low-P/E compounder

CEO Sean Michael O'Connor executed two separate sales totaling 40,000 shares for $4,077,800.00 on November 22 and November 25, 2024, at blended average price $101.94. His post-transaction holdings of 1,130,651 shares represent a -3.4% reduction from prior holdings, indicating a modest trimming rather than a significant exit. StoneX trades at a P/E of 6.28 with strong fundamentals—$468,500,000.00 in latest-quarter revenue, $61,900,000.00 net income, and +9.8% annual revenue growth—suggesting the stock remains attractively valued by conventional metrics. The current price of $46.39 is notably lower than the transaction prices of $100.14 and $103.75, which reflects a material decline in valuation since the sale dates and is not explained by ordinary market drift given the 52-week range of $26.52–$46.47. While O'Connor's cross-ticker track record shows only 1 prior sell with no established timing pattern, the same-ticker history at SNEX includes a prior sale on 2024-11-06 whose outcome remains unmeasurable, limiting inference about systematic insider positioning at this specific holding.
