Muller Luis A, President & CEO, has engaged in 24 reported transactions across three companies—COHU, CLS, and RAL—with a clear buy-side bias, having executed no sell transactions. The only disclosed purchase occurred on June 30, 2025, involving RAL stock with a total value of $100,034.87. All other transactions, primarily involving COHU and CLS, were either acquisitions or dispositions with no reported dollar value, suggesting they may represent option exercises, grants, or other non-market transactions.
Recent activity shows a concentration in COHU, with multiple filings in March 2026, March 2025, and March 2024, all coded as derivative transactions (codes F, J, and A), likely tied to equity awards or expirations. CLS transactions, recorded quarterly between December 2024 and January 2026, similarly lack disclosed monetary values. The absence of outright sales and the single significant purchase in RAL indicate a long-term holding pattern rather than active trading, though the lack of recent market purchases suggests no new accumulation in recent months. The data reflects a disciplined approach, with no material changes in position sizes outside of the RAL acquisition nearly a year prior.
