Brett Argirakis, Group President at Minerals Technologies Inc. (MTX), has demonstrated a clear selling bias in his recent insider transactions, with $1.32 million in total sales outweighing $407,177 in purchases across 28 reported trades. His activity has been exclusively concentrated in MTX shares, with no transactions in other companies. The most significant disposals occurred on November 21, 2025 ($381,459) and June 17, 2024 ($189,643), supplemented by smaller periodic sales. Recent filings show accelerated selling activity in January 2026, with three transactions totaling $274,793 within a six-day period from January 21-26.
Argirakis's buying activity appears more sporadic, with his last recorded purchase occurring on January 27, 2025 ($71,923). The transaction pattern shows consistent annual sales since 2024, with the most concentrated selling occurring in early 2026. While some transactions represent the exercise of derivative securities (coded 'M'), the majority are outright sales (coded 'S') or open market dispositions (coded 'F'). The complete absence of recent purchases alongside multiple high-value sales suggests a sustained reduction in his MTX position over the past two years.
