William Abbey

ARM CCO William Abbey sells 6,566 shares for $2.6M; stock up 102.6% in 30 days, 241.4% in 90 days; prior ARM sales poorly timed

William Abbey, Chief Commercial Officer, executed 2 separate sales totaling 6,566 shares for $2,644,251.56 at a blended average price of $402.72, reducing his holdings by 24.2%. ARM stock has surged dramatically—up 102.6% over the prior 30 days and 241.4% over the prior 90 days—placing the transaction near the upper end of the 52-week range ($427.99 high). However, his prior trades at ARM reveal a consistent timing pattern: all 5 previous sales were followed by continued stock appreciation at the 90-day mark (ranging from +23.1% to +66.2%), meaning none of these prior sells were well-timed (0 of 5 well-timed at 90d). This poor historical timing at the same ticker—combined with selling into an exceptionally strong recent rally—raises questions about whether this transaction represents conviction-neutral activity or misalignment with subsequent price performance.

ARM CCO William Abbey sold 4,200 shares at $343.81 (2026-05-28); stock now +93.6% (30d), +235.9% (90d)

William Abbey, Chief Commercial Officer, sold 4,200 shares (13.4% of pre-transaction holdings) at $343.81, reducing his position from 31,329 to 27,129 shares. The timing of this sale is notable: ARM has delivered explosive gains of +93.6% over 30 days and +235.9% over 90 days since the transaction, with the current price of $408.85 sitting 14.7% above the 52-week high. His prior five sales at ARM (spanning 2026-04-24 through 2026-05-21) show a consistent pattern: none were well-timed at the 90-day mark, with returns ranging from +23.1% to +66.2%, indicating he has sold before each subsequent price advance. This current sale follows the same trajectory—the stock has continued its upward move despite his exit, extending a pattern where his ARM exits have systematically preceded material gains.

William Abbey, Chief Commercial Officer, sold 4,655 shares (4.7K shares) for a total value of $1,336,124.65 ($1.3M), reducing his holdings from 38,284 to 33,629 shares—a 12.2% reduction in his position. The sale occurred at $287.03, while ARM is currently trading at $306.51, suggesting the stock has appreciated since the transaction date. With ARM's strong recent momentum—up 55.9% over 30 days and 144.1% over 90 days—the transaction occurred during a period of significant appreciation for the company. The sale represents a modest portfolio adjustment by a senior executive, though the lack of additional context on timing or schedule limits inference about motivation.
