OH Yoon Ah, VP, General Counsel & Corporate Secretary, has demonstrated a consistent selling bias in their trading activity involving Onto Innovation Inc. (ONTO), with no recorded purchases across 31 transactions. Since 2024, OH has executed multiple sales, including two significant dispositions in March 2024 totaling $770,382.60—$303,300 on March 18 and $467,082.60 on March 15. The pattern continued into 2025 and 2026, with a series of smaller but frequent sales, including $186,212.48 and $68,730 on February 10, 2025, followed by $323,086.50 and $87,039.15 on February 14 of the same year. Recent filings show sustained selling activity in early 2026, with transactions on February 14 ($237,649.62 and $108,832.23) and March 1 ($66,278.23 and $57,642.63). The most recent sales occurred on March 2 and 3, 2026, with $86,527.50 reported. While some filings reflect awards or acquisitions (coded "A" or "M") with no reported value, all monetized transactions have been sales, resulting in over $2.37 million in total proceeds. The data suggests a recurring disposition strategy, with no offsetting buys, though the absence of disclosed acquisition costs for equity awards limits a full assessment of net activity.
