Plisinski Michael P, CEO of Onto Innovation (ONTO), has demonstrated a consistent pattern of selling activity over time, with no recorded purchases in the company’s stock. According to SEC Form 4 filings, Plisinski has executed 45 transactions totaling over $40.1 million in sales, all concentrated in ONTO shares. The most recent trades, occurring in early March 2026, included three sales totaling approximately $1.67 million, with the largest single transaction on March 3 valued at $776,465. Earlier in February 2026, Plisinski sold shares worth over $2.7 million across two transactions, including a $1.94 million disposition on February 14.
The selling trend extends back to 2025, with notable transactions including a $7.67 million sale on January 21 and a smaller $21,211 sale on January 16. While some filings reflect transactions with zero reported value—likely representing grants, awards, or other non-sale events—the overwhelming majority of Plisinski’s activity involves monetizing holdings. The absence of any buys suggests a long-term divestment strategy rather than periodic rebalancing. Given the CEO’s position, the sales could reflect personal financial planning, though the filings provide no explicit rationale. The transactions are spread across multiple dates, avoiding concentrated sell-offs, which may indicate a measured approach to reducing exposure.
